DDSF3333 single phase electronic energy meter

DDSF3333 single phase multi-rate electric meter is designed for measuring single phase active energy.

1. Product Brief Introduction 

The type DDSF3333 watt-hour meter is designed for measuring energy in household and commercial single-phase network services. It's made of electronic single-phase meter modules and rates modules, LCD display, high reliability and  infrared communication functions. Supplying advanced and reliable measurement tools for the single-phase time-of-use measurement. Its performance conform to GB/T15284-2002 multi-rate (TDM) Meter, GB/T 17215.321-2002 1.0 & 2.0 class static A.C active watt-hour meter ,the communication protocol comply with DL/T645-1997 or DL/T645-2007. 2. Functions and Features Four rates,12 time periods,1 minute interval. It may store 12 months of each rate of electrical energy data. It can measure total electrical energy and electrical energy of every rate.The reverse energy is measured and added to the corresponding forward energy. Reverse pulse test and indication functions. Isolated RS485 interface and designed for anti-thunder. protection with password and programming switch, automatically recording the last programming of time and times. Adopting the hardware clock circuit ,and the backup battery adopts the import green environmental protection disposable lithium battery. It may setup time  period,rate,date,time,password etc. It can read via RS485 interface or HHU,which realizes the meter reading and parameter setting.
