The CP-E series is an economical and efficient switch mode power supply series launched by ABB for the industrial automation market, adopting primary switched technology, featuring wide range input voltage, high efficiency, low power dissipation, low heating, and wide ambient temperature range. This series supports series and parallel connection, and can achieve true redundant setup via a redundancy module, meeting the diverse requirements of industrial control systems for power supply reliability and flexibility. The CP-E 24/20.0 is the highest power 24V output model in this series, equipped with two generous capacitors ensuring mains buffering of at least 30ms at 230V AC, enabling stable operation in high fluctuating networks and battery-powered plants.

This power supply adopts standard 35mm DIN rail mounting design (conforming to IEC/EN 60715 standard), snap-on mounting without any tool, compact structure, width 175mm, height 123.6mm, depth 123.6mm, can be directly mounted on standard DIN rails in control cabinets, facilitating integration into automation systems. Screw terminal design for convenient and secure input/output wiring, supporting flexible cables (with ferrule 0.2-4mm²) and rigid cables (0.2-6mm²). Metal housing design with excellent heat dissipation, natural convection cooling, no fan forced cooling required.

In terms of protection functions, the CP-E 24/20.0 has comprehensive protection mechanisms, including no-load protection (continuous no-load stability), overload protection (output power limiting), and continuous short-circuit protection (continuous short-circuit proof, output power limiting continuation), adopting U/I output characteristic curve (constant voltage current limiting). During overload or short-circuit, it automatically enters constant current limiting mode, limiting output current within a safe range, protecting the power supply and load from overcurrent damage; under short-circuit conditions, the power supply will not be damaged, continuously current limiting, and automatically resumes normal output after the fault is cleared, without manual reset or fuse replacement. Integrated internal 10A slow-acting input fuse provides input side overcurrent protection.

The output voltage of this power supply can be adjusted via front-face rotary potentiometer "OUTPUT Adj" within the range of 22.5V to 28.5V DC, convenient for users to adjust output voltage according to actual load and line voltage drop conditions, ensuring the load receives accurate operating voltage.

Q3: Can CP-E 24/20.0 be used in parallel or series? How to configure?

A: CP-E 24/20.0 supports parallel connection and series connection, this is one of the important features of the CP-E series.

Parallel use (capacity increase):

• Up to 3 units of CP-E 24/20.0 same model power supplies can be used in parallel to increase total output capacity.
• After 3 units parallel, total output current can reach 60A, total output power can reach 1440W.
• During parallel connection, output positive (L+) of each unit connected together, output negative (L-) connected together, input side can share the same AC power supply or be powered separately.
• CP-E 24/20.0 has a single/parallel operation sliding switch. During parallel use, set the switch to "parallel" position to optimize current sharing performance.
• Parallel current sharing range is 0.1Ir to 0.9Ir (best current sharing when each unit load is between 10%-90% of rated current).
• During parallel use, it is recommended to adjust the output voltage of each unit to the same value (fine-tuning via front-face potentiometer) for best current sharing effect.
• In parallel mode, max. deviation with load change is ±5% (single mode ±1%).
• During parallel use, note that total output current does not exceed the rated current carrying capacity of wires and terminals, use thicker wires or multiple parallel wires if necessary.

Series use (output voltage increase):

• CP-E 24/20.0 supports series connection, up to 2 units can be connected in series to obtain higher output voltage.
• 2 units of 24V power supply in series can obtain 48V output, total output current 20A (total current after series equals single unit rated current), total power 960W.
• During series use, output positive (L+) of the previous unit connected to output negative (L-) of the next unit, total output taken from the negative (L-) of the first unit and positive (L+) of the last unit.
• During series use, note that output current of each unit does not exceed rated value (20A), total power equals sum of each unit power.
• During series use, note insulation and potential difference between each unit, ensure safety.
• Resistance to reverse feed max. 35V DC, pay attention to reverse voltage protection during series use.

Redundant configuration (reliability improvement):

• True N+1 redundant configuration can be achieved through ABB CP-A RU redundancy unit (part no. 1SVR427071R0000, optional accessory).
• CP-A RU provides decoupling of two CP-E power supply units (≤40V, ≥5A). When one power supply fails, the redundancy unit automatically isolates the failed power supply, and the other continues to power the load, ensuring uninterrupted power supply.
• Redundant configuration is suitable for occasions with extremely high power supply continuity requirements, such as critical process equipment, Safety Instrumented Systems (SIS), data acquisition systems, servers, medical equipment, etc.

Important reminders:

1. During parallel and redundant configuration, please refer to specific wiring diagrams and notes in the ABB CP-E series official manual.
2. CP-A RU redundancy unit needs to be ordered separately, part no. 1SVR427071R0000.
3. During parallel/series/redundant configuration, ensure total load does not exceed total output capacity after configuration.
4. It is not recommended to use power supplies of different models and different power levels in parallel or series, should use same model and same specification power supplies.
5. During parallel use, be sure to set the single/parallel sliding switch to the correct position.

Q4: What protection functions does CP-E 24/20.0 have? Will output short-circuit damage the power supply?

A: CP-E 24/20.0 has comprehensive protection functions, output short-circuit will not damage the power supply.

Protection functions:

1. No-load protection (continuous no-load stability)

• The power supply can safely and continuously operate under completely no-load output (no load connected) conditions, will not cause output overvoltage or damage due to no-load.
• Under no-load conditions, the power supply automatically enters low power consumption mode, reducing its own loss and heat generation.

2. Overload protection (output power limiting)

• When output load exceeds rated value (20A / 480W), the power supply automatically enters constant current limiting mode (U/I characteristic), limiting output current within a safe range.
• During overload, output voltage will decrease accordingly to maintain output current not exceeding current limiting value.
• Overload protection prevents power supply and load from being damaged by overcurrent.
• Under overload conditions, the power supply can operate continuously (but long-term overload operation is not recommended, will cause power supply temperature rise, affecting life).
• After overload is eliminated, the power supply automatically resumes normal constant voltage output.

3. Continuous short-circuit protection (continuous short-circuit proof)

• When output short-circuit occurs (positive L+ and negative L- directly shorted), the power supply automatically enters constant current limiting mode, limiting short-circuit current within a safe range.
• Under short-circuit conditions, the power supply will not be damaged, can operate continuously under short-circuit (Continuous short-circuit proof), output power limiting continues, no manual reset or fuse replacement required.
• After short-circuit is eliminated, the power supply automatically resumes normal output.
• This is an important advantage of this power supply, avoiding power supply burnout caused by accidental short-circuit on the load side, reducing maintenance costs and downtime.

4. Internal input fuse

• Integrated internal 10A slow-acting / 250V AC input fuse, provides input side overcurrent and short-circuit protection.
• If the internal fuse is blown, most probably the device is defective, examination by the manufacturer is necessary, users cannot replace it themselves.

5. Other protection features:

• Active inrush current limiting: max. 25A (5ms) @115V AC, max. 50A (5ms) @230V AC, prevents inrush current from damaging power supply and grid equipment during power-on.
• Mains buffering: at least 30ms @230V AC, at least 25ms @115V AC, maintains output stability during short-term grid interruption or voltage dips.
• Voltage dips / short interruptions immunity: acc. IEC/EN 61000-4-11, dip >95% 10ms / >30% 500ms, interruption >95% 5000ms.
• SELV protective low voltage output: output side is Safety Extra-Low Voltage (SELV), electrically isolated, can be earthed by user with L+ or L- according to needs (PELV).

U/I output characteristic curve explanation:

• CP-E 24/20.0 adopts U/I characteristic curve (constant voltage current limiting characteristic).
• When load current is within rated range (≤20A, Ta≤55°C), the power supply operates in constant voltage region, output voltage remains stable (24V DC).
• When load current exceeds rated value (overload or short-circuit), the power supply operates in constant current region, output current remains constant (current limiting value), output voltage decreases as load impedance decreases.
• U/I characteristic ensures power supply safety during overload and short-circuit, and facilitates current sharing when multiple power supplies are connected in parallel.

Temperature derating explanation:

• Rated output current 20A applies to ambient temperature Ta ≤ 55°C.
• When ambient temperature 55°C < Ta ≤ 70°C, output current derates by 2.5%/°C.
• For example: Ta=60°C, output current derated to 20A × (1 - 2.5%×5) = 20A × 0.875 = 17.5A.
• Ta=70°C, output current derated to 20A × (1 - 2.5%×15) = 20A × 0.625 = 12.5A.
• When using in high temperature environments, always consider temperature derating to ensure the power supply operates within safe range.

Short-circuit troubleshooting suggestions:

1. If power supply output voltage is zero or very low, first check for short-circuit fault.
2. Disconnect all loads, measure power supply output voltage alone. If output recovers to normal (24V), indicates power supply is normal, fault is on the load side.
3. Connect loads one by one, find the specific load or circuit causing short-circuit.
4. Check output wiring for positive-negative short circuit, insulation damage, wiring errors, etc.
5. Observe LED status: green OUTPUT OK on indicates normal, red OUTPUT LOW on indicates output voltage too low.
6. After eliminating short-circuit fault, the power supply automatically resumes normal, no replacement needed.

Important reminder: Although the power supply has continuous short-circuit protection capability, long-term short-circuit operation will cause power supply heating, affecting component life. After discovering short-circuit fault, should promptly troubleshoot and handle, avoid power supply long-term operation in short-circuit state. Internal fuse blown cannot be replaced by user, must return to manufacturer for examination.
