COMPACT 480 VAC PHASE MONITORING RELAY
Carlo Gavazzi has introduced the DPA53 series, a phase monitoring relay with relay output, which detects under-voltage, and improper phase sequence or phase loss.
In a DIN rail mount housing of 17.5 mm, the DPA53 provides a relay type output which can be set as NC or NO. Voltage monitoring ranges are available for 150-230V AC and 320-480V AC. A red LED visually indicates an alarm condition. A time delay built-in for the relay activation is available as a special option.
