New 3KW DC power source offers high-end features from a 2U low-profile unit

Intepro Systems has introduced the PSI 9000, a new 2U high programmable DC power source, providing a 1-3KW supply with a feature set typically found in higher power 3U systems. The PSI 9000 2U power source features an interactive system with touch panel menu navigation that simplifies set up and storing to test profiles. The high-efficiency (up to 93%) unit includes an integrated true function generator. For user convenience, complex test sequences can be loaded from the system and saved to a standard USB flash drive.

A novel feature of the PSI 9000 2U power source is its auto-ranging output. Unlike some DC sources that provide rated power only when maximum voltage is applied to the load, the auto-ranging output stage is capable of delivering a three-times higher output current at reduced voltages. 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 sourcing multiple sources to address low- and high-voltage / current requirements.

“The new PSI 9000 2U power source includes all of the features and functions of its higher-power ‘3U’ cousin,” said Gerard Sheehan, Intepro's chief technical officer. “This easy-to-use unit has front panel controls that include an intuitive LCD display and control knobs for setting voltage, current, power or internal resistance simulation values.”

Additional features of the RoHS-compliant PSI 9000 2U power source include a galvanically isolated analog interface for voltage, current and power programming and monitoring; digital plug-and-play modules supporting RS232, Ethernet, CANopen, Modbus TCP, Profibus, Devicenet; and IEEE/GPIB and SCPI command language support.
