Specifications

FREJA546 / FREJA546N Relay Test System – Specifications
Input Power
Supply	90 to 264 Volts AC, 1Ø, 50/60 Hz, 1800 VA
Outputs
All outputs are independent from sudden changes in line voltage and frequency. All outputs are regulated so changes in load impedance do not affect the output. Each output (VIGEN) module consists of one voltage amplifier and one current amplifier. The voltage amplifier may be converted to a current source. Therefore, one amplifier module may be used to test single-phase current differential relays, including harmonic restraint.
Output Current Sources
The FREJA546 with three VIGEN modules can provide up to six current sources: three high current/high power, and three convertible voltage channels providing lower current/high power.
Per Channel Output
Output Current	Power / Max Voltage
50 mA²	5 VA / 10.0 V RMS
