DATEL’s new DMS-20PC-7-DCM self-powered digital voltage monitor is designed for monitoring –48V intermediate bus voltages in modern telecom/datacom/computer equipment. Its compact size and low power consumption (8mA typical) make it the ideal replacement for older, hardto-read, analog panel meters. Simply connect a –36 to –75Vdc input across the two rear terminals and the meter is fully operational!
