| 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. |
