The Portable Three-Phase Current Source consists of one unit. Two versions are offered for sale:
– EE-120A-3 – Three-Phase Current Source up to 120A on each phase;
– EE-20A-3 – Three-Phase Current Source up to 20A on each phase.
The Current Source is able to generate three-phase currents, synchronized with the service voltage, with unprecedented stability and measurement accuracy. The amplitude and phase-shift of each current is individually adjustable. The values of voltage, current, power, power factor, phase shift, THD and frequency are indicated on the LCD display.
