Auto-Ranging programmable DC power source.

Intepro Systems has introduced the PSI 9000 Series of programmable DC power sources. A single 3U chassis houses up to 15kW of DC power and can be paralleled up to 150 kilowatts. Each chassis features a controller that allows the flexibility of separating into individual sources or paralleling for high-power applications.

The PSI 9000 Series is offered in models with 
output power ratings of 0-3.3kW, 0-5kW, 0-10kW 
& 0-15kW in a single 3U chassis. 
“The PSI 9000 Series is designed to simplify test set up and operation,” said Gerard Sheehan, Intepro's Chief Technical Officer. “Front panel controls include an intuitive LCD display and control knobs for setting voltage, current, power or internal resistance simulation values.” 

A unique feature of the PSI 9000 Series is its auto-ranging output. Unlike competitive DC sources that provide rated power only when maximum voltage is applied to the load, the auto-ranging output stage is capable of delivering 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 buying multiple sources to address low- and high-voltage/current requirements.

The PSI 9000 Series features an interactive touch panel menu navigation system that simplifies set up and storing to test profiles. The industry leading high-efficiency unit (up to 95.5%) includes an integrated true function generator. Complex test sequences can be loaded from and saved to a standard USB flash drive. The unit also includes simulations for PV (photovoltaic) arrays and fuel cells.

Additional features of the RoHS-compliant PSI 9000 Series 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.
