DM72-P digital ph meter hot product Function: DM72-P Single phase Digital Power Meter Mainly used in the real-time measurement and digital indication on single-phase or 3-phase active(reactive) power value in an electric circuit. It can be added modules such as Switching value output (higher and lower limit alarms) modules,analog 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. Technical Parameter: DM72-P digital ph meter hot product
Basic parameters: DM72-P digital ph meter hot product 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 Terminal arrangement and wiring connection: DM72-P digital ph meter hot product ( Attention: If it is not the same with the wiring schema of the diagram behind case, please accord to the one of diagram behind case) 
POWER:Auxiliary power input port of instrument, Auxiliary power supply is AC 220V±10% (please note if you need special power supply). INPUT:Signal input port of instrument, HI represents“+” port of DC input signal, fire wire terminal of AC voltage input signal and inlet wire terminal of AC current input signal. LO: “-” port of DC input signal, the other one wire of AC voltage input signal; the outlet wire terminal of AC current signal input OUT:the alarm contact output port of meter Typical connection: DM72-P digital ph meter hot product
