Carlo Gavazzi DPC01DM48 3-Phase Monitoring Relay
Carlo Gavazzi DPC01DM48 is a true-RMS (TRMS) three-phase monitoring relay designed to safeguard motors, compressors, pumps, generators, and distribution panels against unstable supply conditions. The relay continuously checks the incoming voltage across L1, L2, L3 and neutral, ensuring that connected equipment operates only when the electrical network remains healthy. As a result, expensive downtime and equipment failure become far less likely.
The device detects overvoltage, undervoltage, phase loss, phase sequence errors, and voltage asymmetry in real time. When any abnormal condition appears, the internal output relays switch immediately and isolate the load. Because of its accurate TRMS measurement, the DPC01DM48 maintains dependable monitoring even in distorted or generator-supplied networks. Clear LED indicators show power, alarm, and relay status, so technicians can quickly identify the fault without additional instruments.
Flexible Adjustment & Industrial-Grade Installation
This monitoring relay allows separate adjustment of upper and lower voltage thresholds. Therefore, users can fine-tune protection levels according to plant requirements or generator tolerances. Adjustable asymmetry detection further protects motors from overheating caused by phase imbalance. Additionally, phase sequence monitoring prevents reverse motor rotation during incorrect wiring or maintenance work.
The DPC01DM48 mounts easily on a DIN rail (DIN/EN 50 022) and fits inside a standard 45 mm Euro-norm housing, making it suitable for control panels, MCC panels, and automation cabinets. Two SPDT output relays provide reliable control for contactors, alarms, or PLC inputs. Built in Italy by Carlo Gavazzi, the relay offers long operational life and stable performance in demanding industrial environments.
