Key Features
Ultra-high Electrical Isolation 21kV
21kV insulation withstand voltage is the core highlight of this product. It provides strong electrical isolation between the low-voltage control side and medium-voltage power side, blocks common-mode interference and protects the main control circuit. It adapts to floating high-potential operating conditions of medium voltage variable frequency systems.
Wide Range Regulated Output
Adjustable DC output from 30V to 40V, specially matched with power supply requirements of IGBT power device drivers. It maintains stable voltage under load fluctuation. Maximum power reaches 280W, sufficient to drive multiple driver boards.
Industrial Reinforced Construction
Integrated molded insulation housing with mounting latches and metal base. Shock-resistant and dust-proof design for compact cabinet installation. Fully potted insulation structure resists partial discharge, suitable for harsh environments inside medium voltage cabinets.
Multiple Independent Isolated Output Channels
Built-in 4 independent isolated power output channels. A single module can supply power to multiple power tube drivers at the same time, simplifying internal wiring of power cells and reducing the quantity of power supplies required.
Built-in Full Protection Functions
Integrated overcurrent, overvoltage, short circuit and over-temperature protection. It automatically shuts down output when driver circuit faults occur, preventing cascaded damage to IGBT devices and improving operational reliability of medium voltage frequency converters.
Application Scenarios
It is installed inside power cells of ABB ACS2000 series medium voltage frequency converters, acting as the isolated power supply for IGBT driver boards. Applicable industries: mining, cement, metallurgy, power plants, petrochemical and other heavy-duty medium voltage motor speed regulation applications.
Function: The power cell of medium voltage frequency converter operates at floating potential, ordinary power supplies cannot work in such conditions. This isolated power takes power from 24V low voltage side, converts and provides isolated power to IGBT drivers at floating high potential, solving the high-low voltage isolated power supply challenge.

Frequently Asked Questions
Q1: Which ABB frequency converter is IPS 21-24V-35 AD suitable for?
A1: This isolated power supply is specially designed for ABB ACS2000 series medium voltage frequency converters. It is installed inside power cells and provides isolated power for IGBT driver boards.
Q2: What does 21kV on the product nameplate stand for?
A2: 21kV is the high voltage isolation withstand voltage rating of the module. It creates electrical isolation between the low voltage 24V control circuit and floating medium voltage power circuit, suppresses common-mode interference and ensures safe operation of medium voltage variable frequency systems.
Q3: What are the input and output voltage specifications?
A3: Input: DC24V; Output: adjustable DC 30~40V. Maximum output power 280W. Built with 4 independent isolated output channels to power multiple IGBT drivers simultaneously.
Q4: What fault symptoms will occur on the frequency converter if the module fails?
A4: Module failure leads to loss of power supply to IGBT drivers of the corresponding power cell. The frequency converter will report cell fault, overcurrent or driver error. In severe cases, it triggers trip and shutdown of the medium voltage drive.
Q5: Is a withstand voltage test required after replacing this power module?
A5: After replacement, it is recommended to perform insulation inspection following the ACS2000 maintenance manual to verify isolation performance before power-on commissioning, to avoid power device damage caused by insulation defects.
Q6: Is the module potted? Can it be disassembled and repaired on site?
A6: The integrated insulation housing is fully potted. It adopts reinforced monolithic construction and cannot be disassembled or repaired on site. Replace the whole module directly once faulty.
Q7: What are the requirements for operating ambient temperature?
A7: Designed for medium voltage cabinet internal environment. Operating temperature range: -20℃ ~ +70℃. Ensure adequate ventilation and heat dissipation inside the power cell cabinet to prevent accelerated insulation aging under long-term high temperature.
Q8: Can REV I new version directly replace older IPS power supply versions?
A8: IPS 21-24V-35 AD of REV I version can be used as a direct compatible replacement for the same model. Confirm the part number 3BHE032593R0001 remains consistent before replacement.
