Product Details

The PMC-220 63A Class 0.5 Single-Phase DIN Rail Energy Meter with RS-485 is designed for accurate low-voltage energy metering in industrial, commercial, utility and building energy management applications. Its compact 36mm-wide enclosure combines direct-connected current measurement, multifunction metering, local LCD display and communication functions in a single DIN rail device.

The meter supports a nominal current of 5A and a maximum direct-connected current of 63A, eliminating the need for an external current transformer. Its starting current is only 20mA, allowing the meter to detect and record low-load energy consumption.

The PMC-220 is self-powered from its voltage measurement input and does not require a separate auxiliary power supply. It supports nominal voltages of 220VAC, 230VAC and 240VAC, with a measurement and operating range from 95VAC to 264VAC and a system frequency range of 45Hz to 65Hz.

Multifunction measurements include voltage, current, active power, reactive power, apparent power, power factor and frequency. The meter also records imported, exported, total and net active and reactive energy, apparent energy and accumulated device operating time.

Voltage and current measurement accuracy is ±0.5%, while active, reactive and apparent power accuracy is ±1.0%. Active energy measurement complies with IEC 62053-21:2020 Class 0.5, and reactive energy measurement complies with IEC 62053-23:2020 Class 2.

The PMC-220 has also received approval from the Australian National Measurement Institute under NMI M6-1, with approval mark NMI 14/2/114. The Datasheet identifies the meter as NMI M6-1 Class 1 certified, supporting applications that require approved electricity metering performance in Australia.

An 8-digit multifunction LCD provides local viewing of electrical and energy data. The front panel also includes an energy pulse LED, while an optically isolated solid-state output provides a fixed pulse constant of 1000 impulses per kWh or kvarh for external energy counting and verification.

A standard optically isolated RS-485 port supports the Modbus RTU protocol at selectable baud rates from 1,200 to 19,200bps. This allows the PMC-220 to integrate with SCADA systems, building automation platforms, factory monitoring systems and third-party energy management software.

The meter measures only 36 × 65 × 90mm and supports tool-free DIN rail mounting. Its front panel has an IP51 protection rating, while the device body is rated IP30. The operating temperature range is from −25°C to +70°C, making it suitable for a wide range of indoor electrical distribution environments.

Typical applications include single-phase DIN rail energy metering, industrial and commercial sub-metering, tenant energy monitoring, cost allocation, building and factory automation, utility distribution panels and integration with energy management systems.
