    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.
