Electronic Single Phase Multi-Rate Watt-Hour Meter
The DDSF1022 is composed by the electronic single phase watt-hour meter part and multi rate part, LCD display, infrared or RS485 communication. It has high measuring accuracy, well stability and over load ability, and high reliability. It can measure the time sharing single phase. The meter is according to GB/T17215-2002, DL/T 645-1997.Function and Features1. Each of for periods has different rates: point, peak, smooth and trough. It can be programmed into 12 periods of time and the mini time interval is five minutes;2. All the consumption date can be reserved for 12 months;3. It can auto identify the directional will be auto save and accumulate to the forward;4. It has the function of reverse direction al pulse test and indication; It has the isolated RS485 communication, and design for prevent from the lighting strike;5. Date-copying adopt the pass word and program switch protection, recording the latest program time and degree;6. Meter reading function at power off;
