SDM-630 DIN-Rail Mounting Power Meter (single Or Three Phase) - MID App

Description

Compact DIN-Rail Mounting kWh Power Meter, which can be used for Single or Three phase monitoring. Requires 5A CT's. The Power Meters can be set to either Pulse Output or Modbus output for connection to monitoring systems or Data Acquisition hardware.

For example, our Orchestrator software can be used to monitor and record the data, either via a Modbus Output directly or via connection to an I/O device, which counts the pulses (e.g. Datascan).

MID Approved, LCD Display, setup via front panel
