3-kW dc power source offers high-end features in low-profile unit

The PSI 9000 2U programmable dc power source provides 1- to 3-kW output power, which is typically found in 3U systems. It provides an interactive system with touch-panel menu navigation that simplifies setup and storing to test profiles. The unit operates at up to 93% efficiency and includes an integrated function generator. Complex test sequences can be loaded from the system and saved to a standard USB flash drive.

A unique feature of the power source is an auto-ranging output that automatically increases the output current at reduced voltages. For example, at 600 V, the source offers 5 A and at 250 V, the source provides 12 A. This feature is especially useful when testing products that require varied input voltages while maintaining regulated output power. With auto-ranging, a single system provides a complete test solution, compared to buying multiple sources to address low- and high-voltage/current requirements. It also includes a galvanically isolated analog interface for voltage, current, and power programming and monitoring. It features digital plug-and-play modules that support RS232, Ethernet, CANopen, Modbus TCP, Profibus, Devicenet; and IEEE/GPIB and SCPI command language support. Pricing starts at $2,601.
