Produktinformationen "PM-3112-240P Single-Phase Power Meter, 2 Loops, Modbus RTU, 200 A CT"
The PM-3112-240P CR is a single-phase power meter that measures two independent loops with true RMS values. It reports voltage, current, active, apparent and reactive power and energy, power factor and frequency, updated every second over RS-485 using Modbus RTU. Two clip-on 200 A current transformers are included, so the meter can be fitted to live conductors without disconnecting the circuit.
This variant suits engineers who need accurate energy readings on 1P2W circuits up to 200 A. Its 10 ~ 300 VAC input range and 0.5% active power accuracy at unity power factor make it suitable for monitoring both low-voltage and higher-voltage secondary-side equipment. The two Form A power relay outputs can drive sirens or lights for alarm signalling.
The meter is housed in a plastic DIN-rail enclosure and runs from a +12 ~ 48 VDC supply. Its RS-485 port is isolated at 3000 VDC and offers selectable baud rates and data formats. Typical applications include generator monitoring, switchgear distribution systems and energy management.
