Product Description
Function:
Mainly used in the real-time measurement and digital indication on single-phase active(reactive) power value in an eletric circuit. It can be added modules such as Switch value output( higher and lower limit alarms) modules, analoy value transmitting output module, RS485 communication module are offered at the free option of the user. It can conveniently realize the setting of many parameters including higher and lower limit alarm value, alarm return difference, communication address and communication baud rate, transmitting output specification, transmitting output range by the keyboard of instrument.
Basic parameters:
Rated input voltage: AC100V, 220V, 380V (with programmable PT ratio)
Rated input current: AC 1A or 5A(with programmable CT ratio)
Measuring display range: 0~999W~999kW~9999MW(units shift automatically through status light) or 0~999var~999kvar~9999Mvar (units shift automatically through status light)
Accuracy rating of measurement: ± 0.5%FS± 1digit(active power),
± 1.0%FS± 1digit(reactive power)
Resolution: Top1W(or 1 var), the decimal point shift automatically
Sampling rate: About 2.5 times /s
Polar indication: Can indicate backward power, negative signal displays"-"automatically
Alarm Output: Relay contact output, the contact rating is AC250V/1A
Communication interface: RS485 serial communication,
Applying MODBUS_RTU communication protocol
Transmitting output: Can be set freely as DC0~10mA, 0~20mA
Or 4~20mA, electrical isolation between the signal
Input and auxiliary power supply.
Transmitting output load resistance: ≤ 400Ω
Switching value input: Two-channel of passive contact input ( can customize four channels)
Auxiliary power supply: AC/DC 85~264V
