| Single-phase Split-type Keypad Prepayment Meter |
DDSY23S Single-phase Split-type Keypad Prepayment Energy Meter is an active energy meter adopting digital media to exchange information. After the user loads the purchased energy to the meter, it charges with energy amount as basic unit. The meter is equipped with digital keypad interface to measure active energy and realize prepayment control functions. Its Measurement & Control Unit (MCU) includes Measurement Unit, Real-time Clock Unit, Load Switch and other auxiliary devices, and its Display Unit (UIU) includes Digital Keypad Interface and Display Screen. |
