Twintex PCL 20V series programmable high current DC power supply utilizes a modular parallel architecture; a configuration of two units in parallel achieves a 20V 1000A output (factory-configured), while flexible expansion up to 20V 7800A (factory-configured) is possible to meet high-current testing requirements ranging from the kilowatt to the hundred-kilowatt level.
Specifically optimized for constant-current applications, the PCL 20V series programmable high current DC power supply offers exceptional stability, making it particularly suitable for continuous burn-in and performance verification of low-voltage, high-current devices such as those rated at 12V, 15V, or 18V.
Regarding safety, the units come standard with short-circuit current-limiting protection and offer an optional short-circuit shutdown function, providing protection for both the device under test and the power supply itself. Comprehensive control interfaces, including standard RS232 and RS485, support remote monitoring and system integration, while optional LAN and analog control interfaces facilitate easy integration into automated testing platforms.
With optimized thermal management and high current-sharing accuracy, the PCL 20V series programmable high current DC power supply ensures stable, long-term operation at full load, serving as an ideal power solution for sectors such as power semiconductors, supercapacitors, electric vehicle components, and energy storage units.
