Summary

 

DTSD1353L / DSSD1353L Three Phase Static Multi-Function Energy Meter adopts a design mind that is modularize、hardware modularize to develop a series of meters. According to different requirement of clients, meter used different function module、hardware module、software module. To be with higher accuracy、well stabilization、layout in reason、advanced technology、excellent function、easily operation. It can measure all sorts of power parameters due to be advanced technology level. The meter provide to assess meter of fitting to low voltage transformer distribution area of changed distribution for clients; to be fit for multi-function meter of middle or small users, to be fit for multi-function meter of normal and un-normal industrial three phase assess function. To adopted different communication module may expand communication way to be RS485 and carrier cave ways.

Functions and Features

Communication Functions

.0000000000 2RS485 interface and 1 infrared communication interface, PC or HHU is able to communicate with the meter through three communication interface at the same time without mutual interference

2 RS 485 interface is electrically insulated from the inside of meter, and is designed with anti-lightning circuit

3 communication protocol complies with DL/T645-1997

Output functions

1 active/reactive pulse testing output

2 1Hz clock output function

3 output pulse breadth is 80ms±20ms

Event record function

1 real time measurement voltage of A,B,Cphase ;effective value of current and power, power factor and current frequency

2 record the events of voltage loss, current loss, voltage pass rate, power cut, programming, demand reset, broadcast time-checking etc

Special function

1 The function of infrared remote during power break and awakening by pressing button, infrared remote meter-reading when power break can also be realized

2 the function of fault information indication, alarming and tripping output if overload

Power consumption freezing function

When it is pass 0 o’clock, freezing the current active/reactive total power consumption, record current time sign, and receiving the freezing order of broadcast, it shall be freezing the total consumption of current time positive/negative power active/reactive, and record the time sign

Other types:

1 DTSD51 LZ: Carrier wave multi-function energy meter  different from DTSD51L:carrier wave communication
