Product information "PM-3112-100 Single-Phase Power Meter, Modbus RTU, 2 Loops, 60 A CT"
PM-3112-100 CR is a compact single-phase power meter that measures true RMS voltage, current and power on two independent loops. It suits engineers who need real-time electrical usage data from a monitored circuit without rewiring it, as the clip-on CT fits around the conductor.
This ordering code includes two 60 A clip-on CTs with a 10 mm inside diameter and 1.8 m wire leads, matching the 1P2W, single-CT loop configuration. Current range is 0.05 A to 60 A per CT, and the input voltage range is 10 to 300 VAC, so the meter can be applied on both low-voltage and higher-voltage secondary circuits.
Readings are published over a single RS-485 port using Modbus RTU, with selectable baud rates and data formats. Two Form A power relay outputs can drive sirens or lights for alarm signalling, and the DIN-rail housing supports panel installation.
