DTSY666 3 Phase 4 Wire Prepaid DIN Rail Meter

Characteristics and Range of application:

DTSY666 series 3 phase 4 Wrie prepaid DIN Rail meter (hereafter is the meter) is the most advanced type instrument developed by us adopted the newest technique of personal computer and electronic and currency IC card for purchasing electric energy media. It is assisted by software and hardware technique of computer automation management for getting electric energy fee. It is suitable for measuring rated frequency 50Hz/60Hz 3 phase 4 wire AC active energy. The meter must be mounted in the place which temperature is in -10℃～ 50℃and the relative humidity shall not exceed 85%. And the air should not include corrosive gas, keep away from dust and sand, mildew and insect, etc. 

Main specifications and technical parameter: 

The meter are completely conformed to the relative requirements of the International Standard IEC62053-21(Class 1 or Class 2). 

Remark: In the column of Rated Current , the value before the bracket is basic current value Ib, and the value in the bracket is the maximum current Imax.

Under the conditions of rated voltage, rated frequency and cosφ=1.0, the meter shall start and continuously record electric energy consumption at the current shown in table.

With no current in the current circuit(s), the test output of the meter shall not make more than one impulse at 115% of the reference voltage.

All circuits to the meter case can endure impulse voltage of 1.2/50μs waveform and 6KV peak value. In different electrode to be tested 10 times, the meter shall not discharge or breakdown.

All the circuits to the insulation to the earth can endure alternating current voltage 2KV of 50Hz factual sine wave in a minute.

Working voltage limit：0.8Un～1.2Un
Power loss：≤2W and 10VA
