PS D1 相故障继电器

Introduction: It is a compact version of SP D2. It senses the Negative Sequence Voltage components of the system supply & offers protection against Phase Failure, Phase Unbalance, Phase Sequence Reversal. The user can set the unbalance voltage as per field requirements & optimally use the motors. It is useful for monitoring incoming Mains Power Supply for unbalance voltage faults in Motor Control Panels. It is available in DIN Rail mounting enclosure.

Features: · Monitors 3 Phase Voltage Supply. · Suitable for any System Voltage · Manual / Remote /Auto Reset (Selectable) · Fault Trip Indications (LED’s) · 2 CO output contacts 2 CO output contacts · Sleek DIN Rail mounted D1 Enclosure.

Application Areas: It is useful for monitoring incoming Mains Power Supply for unbalance voltage faults in Motor Control Panels. It is available in DIN Rail mounting enclosure.
