Power Quality Monitoring Control Device (P...

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. Features And Functions Power quality analysis with up to 63th harmonics Convenient user interface and windows based S/W Direct signal acquisition without any outer transducer Self suitability determining of input current and voltage Self H/W and memory diagnosis when turned on User friendly graphic and table form analysis result 4-20mA analog output can be used as transducer 4 channels of contact outputsThe contact outputs can be used to alarm up to 16 user-configurable conditions as listed below Over/Under Voltage Voltage unbalance Over Current Over neutral current Current Unbalance Over kVA Over kWfoward Over kWreverse Over kVARfoward Over kVARreverse Over Demand Over/Under frequency Under PFLead Under PFLag Over Counter Status input change Specification Items Specification Rating Input Voltage AC 110V , AC 0~175V Rating Input Current AC 0~8A Contact input 4CH Dry Contact(min. pulse : 40ms) Control Output 4CH relay contact,Capacity : AC 250V or DC 30V, 10A Auxiliary Output DC 4~20mA, 1CH Power Supply AC 85~264V, 44~440Hz or DC 110~370V Dimension 340(W)X250(H)X109(D), 3.6kg Real Time Measured Parameter
