DESCRIPTION

1 Product Brief Introduction
DDSF1334Type 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 sharing Watt hour Meter and GB/T17215-2002 Class 1 and 2 Static A.C Active Watt-hour Meter, the communication agreement accord with DL/T645-1977 Multi-function Watt-hour Meter Communication Rule.)
2 Function and Features
-Each of four periods has different rates (point period, peak period, smooth period and trough period). Even period of time can be programmed into 12 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 adopts the password and program switch protection, recoding 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 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-adjusting state and the present time-period. It can read via RS485 or hand computer;
-Meter reading function at power off.
