All operating functions are mounted on a panel underneath the protective lid. The twin 3 1/2 digit LCD displays show both output voltage and leakage current.


115V and 230V operation.
50/60Hz frequency selection.
Applies up to 4kV AC.
Displays output voltage and leakage current.
Twin 3.5 digit LCD screens.
Breakdown mode when fast transients can trigger tripping.
