Opto 22 SNAP-AIPM - Single Phase Power Monitoring Module, 85-250 V RMS and 0-10 A RMS Inputs

Descripción

The SNAP-AIPM individually and simultaneously measures single-phase AC volts RMS and amps RMS and calculates true power and volt-amps. Power factor can then be calculated from true power and volt-amp values. Because true power is a signed value, either leading or lagging power factor can be calculated. The SNAP-AIPM module is designed for 85-250 volts and 0-10 amps, but it can also monitor AC line currents greater than 10 amps using a standard current transformer (CT) of suitable ratio. For line voltage larger than 250 VAC, use a stepdown potential transformer. If hazardous voltage or current is to be monitored, an interposing potential transformer and a CT must be used for safety. SNAP power-monitoring analog input modules provide an efficient way to monitor AC voltage and current using a SNAP PAC rack-mounted controller or SNAP PAC brain. These modules can be used with both standard wired SNAP PAC brains and controllers and Wired+Wireless models.89/336/EEC, 2002/95/EC, Defense Federal Acquisition Regulation Supplement
