DTS series of three-phase electronic pre-paid watt-hour meter (hereinafter referred to as the meter), in line with GB / T17215 and GB / T18460 standards, the use of single-chip processing system for data collection, processing and preservation. Its purpose is to measure the rated frequency of 50Hz or 60Hz three-phase active energy.

Product features

		Application of computer management, electricity purchase first electricity.
		Limits the use of power within the rated current range (limited by the power supply department).
		A table of cards, special cards, lost cards without losing electricity, make up card reuse.
		Electric card can transfer data bidirectionally; it can automatically power off alarm users to buy electricity.
		Electricity is zero, automatic power-off; and a certain anti-theft software design.
		Ambient temperature of -25 ℃ ~ +55 ℃, relative humidity does not exceed 85%.

Technical indicators

Start-up: Under the conditions of reference voltage, reference frequency and cosφ = 1.0, the load current is 0.004Ib (level 1) and 0.005Ib (level 2) The meter should be able to measure the power continuously.

Potential: Voltage circuit plus rated voltage 115%, no current in the current circuit, the instrument test output should not produce more than one pulse.

Voltage Range: Normal Operating Voltage: 0.9Un-1.1Un, Limit Operating Voltage: 0.8Un-1.15Un

Power consumption: voltage line power consumption: ≤ 2W and 10VA, current line power consumption: ≤ 4.0VA
