Voltage Indicator ELIN-1 SZ P 12-660 ELEKTRO TREID ET-UNN126

ELIN-1 SZ P voltage indicator is designed to monitor the presence of voltage in AC electrical installations with a frequency of 50Hz and DC voltage of 12-660V. The indicator provides stepped pulse light and sound indication of DC and AC voltage at 12, 110, 220, 380, 660V, 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 testing). Circuit integrity is determined using the energy of a storage capacitor. The capacitor is charged from a DC or AC network with a voltage of 220-380V for 1 minute. One charge is sufficient for operation throughout the entire working day.
