Eberle Controls Voltage Monitoring Relay IMU-1: Additional details
This voltage monitoring relay is designed for monitoring DC and AC voltage for single-phase operation. The measurement voltage is the same as the supply voltage, and the type of voltage is automatically detected. The device features two operating modes: Minimum, which monitors a minimum voltage and switches the relay when the set value is undershot, and Window, which monitors a voltage range and switches the relay as soon as the voltage exceeds or falls below the range. Functions are adjustable from the front with separate settings for switching thresholds. The operating status is indicated by three LEDs: UN, >max., and .
