DPB01CM44 Carlo Gavazzi

DPB01CM44, Three-phase voltage control relay, TRMS measurement, DPB01CM44, xPB01CM44 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, possible surges and subvoltages. 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 overvoltage/undervoltage filters out unwanted activations arising from temporary circumstances. The operating frequency is up to 400 Hz., DPB01CM44, The DPB/PPB01CM44 relay is suitable for network quality control and three-phase load lines, with or without neutral, with nominal supply voltage of 208 WL at 480 WLA and frequencies from 50 to 400Hz. Device configuration: The relay works when all phases are present, the sequence of these is correct and the phase-phase voltage levels are within the established limits. The relay is deactivated when one or more phase-phase voltages exceed the set upper value or when they fall below the set value. The DPB/PPB01CM44 relay is configurable by potentiometers, to set the max. and min. voltage values, the delay to the connection.
