1.Brief introduction:

The DTSF Type Three Phase multi-rate watt-hour meter is composed by the electronic three phase watt-hour meter part and multi-rate part.LCD display,with RS485 communication. It has high measuring accuracy,high reliability,low power consumption,long life etc.

It is in conformity with The standard of GB/T1 5284-2002 and GB/T1 7215-2002.

2.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 12 periods of time and the minimun time interval is 1 min.

-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 isolated RS485 communication,and design for prevent from the lightning strike.

-Data-copying adopt the password and program switch protection,recording the lastest program time and degree.

-It adopts the hardware clock circuit,the lowest current xonsumption,the battery is one-time and environmental protection lithium battery.

-It can setup the meter number,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 harware 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.
