DUA52C724 DUA52 monitoring relay, single-phase, 8 - 28 V DC, undervoltage

The DUA52 is a measuring relay for monitoring DC circuits for undervoltages. It measures the voltage of its own power supply. Depending on the version, the relay operates in the measuring range from 8 - 28 V DC or 38 - 58 V DC. Two potentiometers can be used to set the low voltage limit and the hysteresis. Typical applications include: monitoring of backup batteries, batteries of diesel generator sets and similar equipment.
