1. Overview
DDSY1352 single-phase prepaid electric energy meter and DTSY1352 three-phase prepaid electric energy meter are new prepaid electric energy meter integrating measurement and control. It supports RF recharge (or card recharge) and remote recharge with many control modes, such as prepayment control, time control, malignant load control, etc. The built-in 100A large capacity magnetic holding relay can realize internal switching closing of the meter. It can also provide the dry contact output control to control the external circuit breaker to achieve the trip function. It is widely used in pre-paid electricity management in commercial plazas, residential dormitory and school dormitory.

“■” means standard, “□” means optional
Notes: 1. DDSY1352's infrared communication and the second RS485 can only choose one.
2. Prepaid function need to be used in conjunction with our prepaid management system.

Auxiliary wiring diagram
Notes: 1. 17 and 18 are clock and active pulse multiplexing terminals, and the default is the active pulse.
2. (40-41), (42-43) cannot be used by default when the meter has internal control function. If necessary, it should be specified in the order.
3. When tripping, it is necessary to introduce voltage to 41, and 40 is connected to the control terminal of the circuit breaker.
4. 42 and 43 closing terminals can be used to control the closing of specific devices such as electric operating mechanisms.
5. The fuse withstand voltage of 41 and 43 terminals should be greater than the voltage level of the current voltage system, and the rated current should be 3-5A.
