Compatible with 2 or 3 wire, 120, 208 or 240 Volt circuits.

Kilowatt-hours (kWh) consumed is displayed across the top portion of the LCD Display. There are no display multipliers required.

Volts, Amps and instantaneous Kilowatts (KW) are displayed below the kWh display with 3-digit resolution .

Energy pulse relay set to 1 pulse per 1 kWh.

Calibration

The voltage and the current terminals simply unplug to facilitate field calibration. A portable meter tester can easily plug into the removed terminals.

Also, there are two rows of CT terminals used when paralleling two sets of CTs. Remember Current Sensors with voltage outputs cannot be paralleled. Voltage is not additive, where current is.

Communications

There is a RS485 ModBus RTU terminal next to the relay. This port works with the Communication Gateway/Intelligent Converter that plugs into the RS232 comm. port in a PC. Several software packages are available. Call the for more information.
