Diversified Electronics 800.727.5646 atcdiversified.com POWER QUALITY SP0327A 1/4 HP True Power Band Monitor OVERVIEW
FEATURES
- Accurate motor load detection
- Superior accuracy compared to current monitors
- Comprehensive power compensation True power monitors detect motor load more accurately than current monitors. The current, as measured by a cur - rent monitor or ammeter, may only vary slightly between the motor’s no load and full load conditions. A true power moni- tor has better accuracy and resolution because it calculates power consumption from the line voltage, motor current, and power factor. OPERATION When control voltage is applied, the output relay is de- energized. If the monitored power remains below the preset “C.I.” point for longer than the 15 s pick-up delay, the out- put energizes. When the monitored power increases above the preset “DIFF” point, the SP0327A automatically resets and the output relay de-energizes. *NOTE: Exceeding the maximum input ratings may damage the device.
