 This reference design is a class 0.5 single-phase standalone or microprocessor-based meter with tamper detection for power line systems of Vnom = 140 to 300 V RMS, Inom/Imax = 2/20 A RMS, flin = 45 to 65 Hz and Tamb = -40 to +85 °C.
The values of the measured energy in the standalone meter can be provided by a stepper motor display.
In the microprocessor-based meter, a control board with a microprocessor can drive an LCD which can be used to display the measured values of active, reactive and apparent power consumption.
Two shunt resistors are used for current sensing. |
