- Three-phase panel meter with real-time metering and power-quality functions
- On-board data logging, waveform capture, waveform recording and programmable setpoints
- RS-232 and RS-485 communication with supported protocol options
3720 ACM is a Power Measurement three-phase panel meter that combines electrical metering, power-quality analysis, programmable setpoints, event logging and waveform capture or recording.
The instrument supports configurable voltage and current inputs, relay or solid-state output options, status inputs and field-configurable serial communication for integration with a monitoring or control system.
Because the base name does not identify every installed option, ordering and replacement work must verify the rear label and the fitted 277, 347, XAMPS, SSR, P24/48, XTEMP, MPCC, MPE or related option configuration before wiring or commissioning.
Availability, condition, price, and shipping time for 3720 ACM are confirmed during quotation.
