3-Phase Power Rig

Our range of fully synthesised AC Voltage and Current Power Sources are ideal for application in electricity meter testing, calibration laboratories, Aerospace/Military and a multitude of other applications. The sources are based on state of the art switching amplifiers providing excellent performance, ruggedness and exceptional load tolerance.

Condensed into a 6u 19" SubRack, our source systems are fully configurable and available in single phase and 3-phase variants with output capabilities of 30-600V on the voltage channels and 10mA to 120A on current at powers of 30VA to 300VA per channel.

Digital control via a single communications link allows fast, on-the-fly control of set-points, phase and frequency. This provides stand alone operation with just a single host or real time closed loop control with the addition of a reference standard and associated software.

All our systems are electronically protected against overload, in the form of excessive burden, transient peaks and short/open circuit conditions for Voltage and Current respectively.

Key Benefits

Key Features

Our Power Sources are fully modular and as such can be supplied in a configuration to suit your needs. Voltage and Current sources can be configured to produce a system from just a single phase and single channel upto a full 3-Phase Voltage and Current Source system.

We boast USB and RS232 interfaces to allow full and real-time control of all parameters via a single host. The fast response of our Sources lend themselves perfectly to integration into a closed loop configuration allowing the superfine and real-time control of set points. A Microsoft Windows® application is supplied providing you with full control of the power source via the USB or RS232 interfaces.
