DDSF1977 Type Electronic Single-phase multi-rate watt-hour meter
PRODUCT BRIEF INTRODUCTION
The DDSF1977 type electronic single-phase multi -rate watt-hour meter 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, well over-load ability and high reliability. It can measure the time-sharing single phase All the indexex of the meter comply with the standard of GB/T15284 - 2002 Multi-rate ( time - sharing ) Watt-hour Meter and GB / T 17215.321-2008 Class 1 and 2 Static A. C active Watt-hour Meter, the communication agreement accord with DL/T645-1997 Multl-function Watt-hour Meter Communication Rule.
FUNCTION AND FEATURES
Each of four periods has different rates ( point period, peak period, smooth period and trough period ) Every period of time can be programmed into 10 periods of time and the minimum time interval is one minutes;
All the consumption date can be reserved for 12 months;
It can auto identify the directional, will be auto save and accumulate to the forward direction power counter It can auto save the reverse direction power, starting time and the total time;
It has the function of reverse directional pulse test and indication;
It has the isolated RS485 communication, and design for prevent from the lightning strike;
Date-copying adopt the password and program switch protection, recording the latest program time and degree;
It adopts the hardware clock circuit, the lowest current consumption, The battery is one - time and environmental protection lithium battery;
It can setup the meter nurnber, bureau number, time-period, rate, date, time, meter reading time, password and the initial electric power;
It can indicate the short voltage of the backup battery, the hardware state of the meter, the communication state of the meter, the clock state, the directional electric energy, time-adiusting state and the present time-period It can read via RS485 or hand computer;
Meter reading function at power off.
