Voltage indicator UNN KOMBI (12-380) HV ELEKTRO TRADE ET-UNN115VL

UNN KOMBI (12-380) VL voltage indicator is intended for monitoring the presence of voltage both on overhead lines and in AC and DC electrical installations with a voltage of 12-380V at a frequency of 50Hz. The indicator provides stepped pulse light and sound indication of AC and DC voltage 12, 50, 110, 220, 380V, allows determining the polarity of DC and the phase of AC voltages, and the integrity of electrical circuits with an external resistance from 0 to 100 kOhm (light and sound continuity test). Circuit integrity is determined by the energy of a storage capacitor. The capacitor is charged from an AC or DC network with a voltage of 220-380V for 1 minute. One charge is sufficient for operation throughout the entire working day.
