Product Description Ordering Key
DUA 52 C 724
DUA52 is a voltage monitor- ing relay that measure its own power supply. The measuring ranges are 8-28 VDC and 38-
58 VDC. It has separate potentiometers for setpoint
and hysteresis. Typical appli- cations are monitoring of backup batteries, batteries on diesel generator sets and the like.
