1电流互感器+分流
is a mono phase energy meter with current transformers plus shunt. This measurement board is based on STPM01 energy meter application specific standard product designed to address a wide range of electricity metering requirements. STPM01 is able to work as a peripheral but also as a standalone device, since it can permanently store configuration and calibration data. This metering module can be used to build a Class 0.5 single phase standalone or microprocessor based meter with or without tamper detection for power line systems of UNOM 140V to 300VRMS, INOM/IMAX 2/20ARMS, fLIN 45Hz to 65Hz and TAMB -40 to +85degC. In standalone mode, a stepper motor display should be connected to pins W5 and W6. A user can select the type of stepper or the constant of output pulse frequency by changing LVS or KMOT configurations respectively. In Microprocessor based mode, a control board with a microprocessor should be connected to male connector P1 of module using a 10 wire flat cable.
