ABB IPS21-35AD 3BHB017688R0001 High-Voltage Isolated Power Supply Module | 30-40V Output/280W | 21kV Isolation | Manufactured by Sécheron | Order Available

1. Product Overview

The ABB IPS21-35AD (Part Number 3BHB017688R0001, Revision J) is a high-voltage isolated power supply module (IPS) designed and manufactured by Sécheron Elektrotechnik GmbH (Switzerland) for ABB. It is primarily used for driver circuit power supply in ABB medium-voltage variable frequency drives and IGCT converter systems.

This module converts the input power into a stable adjustable DC output through high-voltage galvanic isolation, with an output voltage range of 30-40V DC and output power of 280W. The most notable feature is the 21kV isolation voltage between input and output, which effectively isolates high-voltage transients and electromagnetic interference between the medium-voltage main circuit and low-voltage control/driver circuits. It provides safe and reliable isolated power for IGCT (Integrated Gate-Commutated Thyristor) driver boards, control circuit boards, and other auxiliary circuits.

The IPS21-35AD is widely used in ABB ACS5000, ACS6000, and other medium-voltage drive systems, as well as other industrial converters using IGCT technology, Flexible AC Transmission System (FACTS) devices, and renewable energy conversion equipment. It is a key auxiliary component in medium-voltage power electronic systems.

7. Frequently Asked Questions (FAQ)

Q1: Is the output 24V? Why do many online sources say 24V/35A/840W?

A: No. According to the physical label, the IPS21-35AD output voltage is 30-40V DC adjustable, output power 280W, and isolation voltage 21kV. The "24V/35A/840W" specification published by many online channels is incorrect, possibly confused with other models. Please refer to the physical label and ABB official datasheet for accuracy.

Q2: Is the manufacturer ABB or Sécheron?

A: The physical label shows the manufacturer as Sécheron Elektrotechnik GmbH (Switzerland), with ABB part number 3BHB017688R0001. Sécheron is a professional manufacturer of electrical isolation equipment, producing this high-voltage isolated power module for ABB. The product belongs to ABB's medium-voltage drive system spare parts portfolio.

Q3: What does 21kV isolation mean? In what applications is it used?

A: 21kV isolation means the input and output can withstand a voltage difference of up to 21,000 volts without breakdown. This is a very high isolation level, primarily used for IGCT driver board power supply in medium-voltage drives (such as ACS5000/ACS6000, voltage levels 2.3kV-6.9kV or higher), ensuring complete galvanic isolation between low-voltage driver circuits and the high-voltage main circuit, protecting equipment and personnel safety.

Q4: What is the output current? Why isn't it on the label?

A: The output current is not directly marked on the physical label — this parameter is to be confirmed by the manufacturer. Based on the output power of 280W and output voltage range of 30-40V, the estimated output current is approximately 7-9A (280W ÷ 35V ≈ 8A). However, this is only an estimate. For accurate output current parameters, please refer to the ABB official datasheet. If you need confirmation, we can assist in querying the manufacturer.

Q5: What does Revision J mean? How does it differ from other revisions?

A: REV J indicates hardware revision J (Revision J). Different revisions may differ in component selection, layout optimization, or performance improvements, but are usually functionally and interface compatible. It is recommended to use the same revision as the original equipment for replacement, or confirm backward compatibility of newer revisions.

Q6: Can you provide the datasheet?

A: You can contact our sales team to request the ABB/Sécheron official product datasheet. Since this product is a dedicated medium-voltage drive spare part, some technical documentation may require a Non-Disclosure Agreement (NDA) or project information before release. We can also verify key parameters based on the physical product label.

Q7: What is the lead time?

A: This model is available via ABB/Sécheron factory order. For medium-voltage drive spare parts, standard lead time is approximately 4-12 weeks, depending on factory stock and production schedule. Some commonly ordered models may have channel stock or used surplus units available. Please contact sales to confirm current lead time — we will coordinate the fastest delivery option available.
