Lightweight Digital Power Meter Remote Control With Relay Alarm Output

Lightweight Digital Power Meter Remote Control With Relay Alarm Output

1. Quick Overview:

Series of WD-9Q3 Single-phase Power Meters are used for measuring and monitoring the power distribution system. This series of meter can measure the voltage, current, active power, reactive power, apparent power, power factor, frequency, active energy, reactive energy and some other power parameters.

It combines the measurement, the analysis and the operation together, makes the information become clearer, and the operation become easier.

2. Technical Parameters:

3. Features:

• Measurement parameter:3 phase voltage,current,active power,reactive power,appearant power,frequency,power factor,4-quadrant converter electric energy and bidirectional kwh ect.
• Two loop on-off input/output,with remote control and measure function,
• Isolation for input and output.
• Ture effective value measure and display.
• Optional 4-20mA transmit output for voltage,current,active power,reactive power,frequency,power factor.
• With 2 loops energy pulse output, 2 programable alarms
• With RS485 communication, Modbus Rtu
• With harmonics measure and display function for voltage and current.
• Optional multi-tariff rate function and demand , maximum demand statistics function.

4. Typical Wiring Diagram:

5. Applications:

The meter may be used as a data acquisition unit for an Intelligent Power Distribution Automation System or a Plant Automation System that integrates process instrument and electrical requirements. The available serial communication option allows for fast and simple integration with these systems. The Meter is also suitable for any AC applications where there is considerable distortion of current waveform from nonlinear loads such as a VVVF Inverter, Ballasts and Switching Power Supply.
