Overview:
DDSYF 127 single phase multi-tariff prepayment meter is a meter integrated with prepayment function unit and multi-tariff function unit. This meter support 4 tariff and 12 tariff period. It features high reliability, strong structure and convenience meter reading. It is new generation meter which very practical for commercial application or some temporary electricity places. The meter is equipped with optical pulse output and can be read by TTU.
Main function:
* Measure positive and negative active energy for 4 different tariffs.
* Max 4 tariffs, 12 tariff periods.
* Read and program meter via optical port by TTU
* Cyclic display of max 14 items, the order and interval of display items is programmable.
* Record last 12 months' total active energy and each tariff’s active energy.
* Purchase before use
