PCL 45kW Programmable DC Power Supply 30V 1500A to 1500V 30A & 2000V 22.5A

Twintex PCL 45kW series Programmable DC Power Supply, composed of three paralleled 15kW power modules integrated into a standard 12U mobile cabinet, features a compact structure for flexible on-site deployment. Its modular design balances current costs with future scalability; the cabinet supports direct expansion to 60kW (by adding one module) without requiring a cabinet replacement, fully accommodating future power growth needs. Additionally, we offer comprehensive customization services, allowing for the selection of larger cabinets to provide ample space for further future expansion.

The PCL 45kW Programmable DC Power Supply offers a wide output range, delivering up to 1800A at 20V or 22.5A at 2000V. It comes standard with RS232/RS485 communication interfaces and supports real-time recording and export of test data (exportable to Excel format via PC software). Engineered for high reliability, it is ideally suited for high-power static testing scenarios, such as full-load temperature rise tests for electric vehicles and controllers, constant-current/constant-voltage charge-discharge cycle verification for energy storage battery packs, static MPPT efficiency scanning for PV inverters, and long-term withstand voltage/aging tests for high-voltage IGBTs and relays. With its modular redundant design and precise CV/CC modes, it provides a stable, low-ripple high-power static load, meeting the rigorous reliability requirements of both R&D verification and mass production testing.
