The MVD series of live line AC/DC voltage presence indicators provide a means to detect visually the presence of dangerous voltages in medium voltage lines, capacitors or busbars. The MVD15, MVD25 and MVD30 come in module form easy to be installed in power modules or electric cabinets. Digital multimeters are limited to 1kV DC or AC maximum so there is a need to reliably and safely identify the presence of hazardous voltages in power electronics equipment. Four high intensity red LEDs will blink at a rate greater than 2Hz when the input voltage is higher than the activation voltage. Blink intensity and rate remain constant through the entire activation voltage range.  Also, the MVD series of detectors are extremely tolerant to input over voltages.

The MVD30F and MVD25F model provides visual signaling through a 1.5m fiber optic (different lengths available) that carries the light pulse to a panel mounted light pipe, thus avoiding the need for auxiliary supplies on the low voltage area to signal the presence of voltage.
