Key FeaturesInput connector: Three-position screw terminal block Isolation (ground): Input is fully floating. Either input polarity can be strapped to chassis ground at the input terminal block. Isolation input to output: 500 VAC, 710 VAC minimum Power supply status: The fault detector monitors all three output voltages and provides a visual (panel LED) and fault output if any output voltage decreases by 10%. Panel status LED: Green LED on with no fault and DC power applied. Green LED off with fault or no DC power applied. Output status line: Open collector. High impedance state with no fault.
