ACR1252U Carlo Gavazzi

ACR1252U, Three-phase voltage and frequency control relay with NFC, ACR1252U, DPD is a configurable multifunction three-phase control relay, suitable for triangle or star networks. Protects loads against incorrect phase sequences and neutral and phase losses. In addition, it allows to establish limits of voltage, frequency and asymmetry and provides output signals. DPD is supplied with factory default alarm values. If these are not suitable, you can modify them based on your own requirements. DPD has two independent relay outputs. Three front LEDs visually indicate the status of the outputs and allow to differentiate the alarms. Through the DPD app, the user can reprogram the unit at any time or check the operating status of the device., ACR1252U, DPD is suitable for all applications that require monitoring the presence of phase, correct phase sequence, voltage, frequency and quality of the three-phase charging network: elevators, escalators, air conditioning, material handling, pumps and compressors.
