| DDSY23S Keypad Prepayment Meter |
Keypad Prepayment Meter uses digital media as the data exchange media. The pre-purchased kWh will be loaded by user and the settlement will be done in terms of kWh. The meter is equipped with digital keypad interface, which is used for active energy metering & prepayment controlling. Besides the meter also has Infrared communication, RS485 or RS232 communication, metering element, real time clock unit, load control switch and other auxiliaries. |
