Keypad Meter
1. Brief Introduction
This is a three phases four wires prepayment keypad split type meter, which is based on virtual medium, the data encryption process complies with international standard IEC62055.
Built-in 100A relay in MCU which can trip when over load, balance run out, tamper happen and so on.
RF communication between MCU and CIU, so user can recharge or check balance at home from CIU conveniently, and CIU will display MCU’s real time data for user.
