TSD169/DSSD169 type electronic three-phase multi-functional kilowatt-hour meter is a product of electrical energy measuring which adopt new generation high performance chip and technology. The product conform to DL/T614-2007 and DT/T645-2007 standard. The meter is consist of voltage and current transformer, high-speed transformer EPROM and CPU etc.

Main function and feature: Precise measurement on forward and reverse power in active and reactive four-quadrant reactive max Demand Precise measurement on each phase voltage,current,active and reactive watt. 4 tariff-rate to be set per day and 12 season-cost rate ranges per year,4 sets of tariff rate for flexible and adaptive use.

Recording meter reading automatically buy the designated data and store the date of last and last two month. Meanwhile, max demand of current month resets to zero either automatically or manually. 1-2 day in a week to be set as day-off and converted into specific day-off time bucket as required.

Records and display loss of pressure information, power failure information, sets parameters, back-up battery service time and state of parameters. Infrared remote controlc and computer programming,meter reading,and can also drive online with the department of communications.
