Single-phase electronic prepaid energy meter with front smart card slot.
The DDSY6661 is a single-phase electronic prepaid electricity meter with an integrated smart card slot, engineered for apartments, commercial plazas, and managed rental properties across Pakistan. Tenants load electricity credit onto their physical IC card at the property management office or vending terminal, then insert the card into the meter to instantly transfer kilowatt-hours. The meter features a heavy-duty internal disconnect relay that automatically cuts power when credit is exhausted and restores it immediately upon insertion of a valid recharged card.
