ELIN-1 SZ M ELEKTRO TRADE ET-UNN123 voltage indicator

ELIN-1 SZ M voltage indicator is intended for monitoring the presence of voltage in 50Hz AC electrical installations and 12-660V DC. The indicator provides stepped pulse light and sound indication of DC and AC voltage. Discrete values of the indicated voltage: 12, 110, 220, 380, 660V, also allows determining the polarity of DC and the phase of AC voltages.
