DPB02CM44 Carlo Gavazzi

DPB02CM44, Three-phase voltage control relay, TRMS measurement, DPB02CM44, xPB02CM44 relays are three-phase electrical network monitoring devices. They can operate in three-phase and three-phase + neutral networks where they detect, in addition to phase losses and the correct phase sequence, the possible asymmetry between phases. They are powered through the monitored network with a wide input range, thanks to the internal switched power supply. Consumption, dissipation and, consequently, heat are very low. An alarm delay of up to 30 s in cases of asymmetry filters out unwanted activations arising from temporary circumstances. The operating frequency is up to 400 Hz., DPB02CM44, The DPB/PPB02CM44 relay is suitable for quality control of the network and three-phase motors, or other loads that require a balanced three-phase voltage, with or without neutral, with nominal supply voltage of 208 WLV at 480 WLV and frequencies from 50 to 400Hz. Device configuration: The relay works when all phases are present, the sequence of these is correct and and the asymmetry is below the established limit. The asymmetry alarm is triggered when the voltage difference, in percentage, between the phase with the highest value and the phase with the lowest value exceeds the adjusted limit. The DPB/PPB02CM44 relay is configurable by potentiometers, to establish the values of the asymmetry and delay to the alarm connection.
