DPA53CM48 - Power Monitor, Carlo Gavazzi 380-480vac

DPA53CM48 - Carlo Gavazzi | Elevator 3-Phase Voltage Monitoring Relay

The DPA53CM48 3-phase monitoring relay protects elevator traction and control circuits by detecting incorrect phase sequence, phase loss, and undervoltage on 380–480 VAC (±15%) lines. A front-dial knob lets you fine-tune the undervoltage setpoint for reliable fault response even under regenerated voltage conditions.

Housed in a slim 17.5 mm DIN-rail enclosure, the DPA53CM48 is powered directly by the measured phases and features a SPDT electromechanical relay output rated 5 A @ 250 VAC. Green and yellow LEDs indicate power-on and relay status. Operating over 50–60 Hz, it’s IP20-rated and UL-recognized for North America and CE-marked for global use.
