USAGE AND APPLICATION
DTS855/DSS855 which is three phases static active energy meter and which adopts overseas advanced double-ways electric energy measurement digit circuit chip and the workmanship of SMT and which has the characteristic of double-ways power measurement and count, high precision, high reliable and high over-load, low power loss, light weight and low cost.
The product be used to using in the environmental temperature of -40℃~+55℃ and the relative humidity not more than 85%.
The product meet the requirement of technology for the three phases static energy meter, which is conforming to the standard of IEC61036
FUNCTION AND CHARACTERISTIC
◆Double-ways active electric energy count and needless of adjusting for long work
◆Supplied by three phases power supply
◆The function of loss of phase instruction, phase failure light is on when three phases is full of voltage and phase failure is off when phase failure occurred in one or two pahses.
◆Wide voltage,current and operating temperature range

Note: impulse constant is in compliance with the electric energy panel mark.
STARTING
When the rated voltage,frequency and power factor equal to 1 and minus current is 0.4% of standard current, the electric energy impulse output light should instruct continually and the energy meter has the output of electric energy impulse.
NO-LOADING
When imposing 115% rated voltage and current circuit is off there is no electric energy impulse output.
RATED FREQUENCY: 50HZ
POWER LOSS: voltage circuit≤2W and 10VA; Current circuit≤4VA
ENVIROMENTAL CONDITION:
normal work temperature:-20℃~+45℃
Limiting work temperature:-40℃~+55℃
Relative humidity:<85%
WEIGHT: about 1kg
DIMENSION:228mm×145mm×68mm
WORK PRINCIPLE
Shown as follows, three phases voltage and current pass through samples circuit, be converted to PWL signal and input to Special IC integrate circuit, the output pulse that is proportional to the input power drives the step motor register, and achieve the three phase energy measure. The energy meter has impulse output for testing.

TRANSPORTATION AND STORAGE
It is not strongly shaking when transporting and unpacking, which should conform to the technical condition for package of meter and instrument specified.
The energy meter should be stored in the original package , and which the local temperature for storage is 0~40℃、relative humidity is not more than 85% and no corrosive gas in the air.
The energy meter should be put on the shelf in the warehouse for storage and not more than four boxes of height. The height for energy meter of each package is not more than 10 pieces when unpacking.
DURATION OF GUARANTY
Within eighteen months form the date of selling, if find any discrepancy said in the standard of enterprise,manufacturer agrees to repair or change for free. When the user obey to the requirement of instruction manual and the seal of manufacturer is complete.
