ADF400L series multi-user electric energy meter
The ADF400L series multi-user electric energy meter can achieve up to 12 three-phase or 36 single-phase direct access measurement or 12 three-phase mutual inductor access measurement, a hybrid of direct access and mutual inductor access through module combination measurement method.
Display method:LCD(Field) Energy metering: Active energy metering(Forward and reverse), Reactive power measurement(Forward and reverse) Electricity measurement: Voltage, current (zero sequence current), power factor, frequency, active power, reactive power, apparent power Harmonic function: Total harmonic content, sub-harmonic content (2~31 times) |
Three-phase unbalance: Voltage and current unbalance DI/DO: Main module 2DI2DO Transformer access to the slave module 2DI4DO (direct access to the slave module without) LED Instructions: Pulse light indication Communication: Infrared communication RS485 interface (main module) supports MODBUS Historical power: Historical Electricity in Last December |
