Single phase prepaid energy meter
Introduction:
DD(T)SY395 series single phase and three phase keypad prepayment energy meter are produced according to IEC62052-11/62053-21 standard with STS certificates. They are used for measuring active electricity of 50 or 60 HZ rated frequency, 220V(singles phase) or 220V/380V(three phase) rated voltage. The series meters can purchase electricity and recharge by keypad through mobile, ATM and POS, combined with electricity sale system for prepayment management. The series meters used famous, long lifetime, industrial components and LSI&SMT production. The meters have such specifications: high reliability, low consumption, long lifetime and multi functions.
