Power Quality Monitoring Control Device

Power Quality Monitoring Control Device (PM-300)

PM-300 is a microprocessor based measuring and control device including panel metering, power quality measurements and peak demand control. It directly interfaces with VTs and CTs and calculates true RMS current, voltage, power, energy, harmonics and other values. It provides an analog output channel for interface with SCADA RTU and contact outputs for alarms or controls. SCADA system for industrial , commercial power distribution can be economically established. RS-232c and 485 ports are used for digital communications with remote host computer or other PM-300 devices.
