Programmable High Current DC Power Supply 40V 1125A 1500A to 3000A 4875A

Twintex PCL 40V high-current, high-power power supply features a modular parallel architecture. Starting from a base configuration of 40V 1125A (45kW), it allows for seamless expansion up to an impressive 40V 4875A (195kW) through easy paralleling. This flexibility perfectly meets power requirements ranging from R&D validation to large-scale production testing, making it particularly well-suited for high-volume burn-in and reliability testing of high-power 30V-40V devices.

Specifically designed for testing core components such as MOSFETs, IGBTs, power modules, and DC-DC converters, this series delivers a stable, clean, high-current output, ensuring the rigor and effectiveness of burn-in screening and lifespan testing.

To be more specific, two applications are listed below for some typical models.

 40V 1500A 60kW Programmable High Current DC Power Supply PCL40-1500:

• Burn-in testing for high-power devices and power modules: Used to perform full-load burn-in tests on components such as high-power IGBT modules and power modules, screening for early-stage failures and ensuring product reliability. The 60kW power output allows for simultaneous powering of multiple units under test, thereby increasing efficiency.
• High-volume burn-in testing for passive components and simple active devices: DC power supplies are required to apply voltage during the high-volume burn-in or reforming of electrolytic and tantalum capacitors. Power supplies are also needed to provide operating current during burn-in tests for components such as resistors and relays.

40V 3000A 120kW Programmable High Current DC Power Supply PCL40-3000:

• Limit testing for high-power power electronic devices: Used to conduct extreme current surge tests, short-circuit withstand capability tests, and power cycling burn-in tests on next-generation power semiconductor devices—such as ultra-high-power IGBTs and SiC MOSFETs—to verify their reliability under extreme conditions.
• Frontier Research and Specialized Applications: Providing power for high-power magnets or specialized loads in frontier scientific research, such as high-energy physics, or conducting current-carrying tests on specialized cables and sensors, including superconducting cables and high-current sensors.
