Product use

DDS electronic single-phase watt-hour meter, used to measure the rated frequency 50Hz AC single-phase active energy, and with RS485 communication interface. The product uses advanced microelectronic technology for energy measurement, the performance index in line with GB / T17215-2002 standards. With high precision, high reliability, high overload, low power consumption, small size, light weight can be used as a remote set CTP terminals and so on.

Technical index

		Meter constant 1600imp / kW ? h / 3200imp / kW ? h (based on the panel logo).
		When the load current is 0.4% (Grade 1.0) [0.5% (Grade 2.0)] at the rated voltage, rated frequency and power factor of 1, the watt-hour meter should be able to continuously measure the electric energy.
		Slippage: No pulse of electrical energy is output when a 115% rated voltage is applied and the current loop is open.
		Normal operating voltage: 0.9 ~ 1.1 Rated voltage; Operating voltage limit: 0.8 ~ 1.15 Rated voltage; Insulation voltage: ≥ 2000VAC; Power consumption: ≤ 2W and 10VA.
		Climatic conditions are as follows: Normal operating temperature: -25 ℃ ~ 45 ℃; Limiting operating temperature: -45 ℃ ~ 55 ℃ (-25 ℃ following to be customized); Storage and transport temperature: -25 ℃ ~ 70 ℃
		Humidity range is as follows: Annual average humidity: ≤ 75%; 30 days a year (natural diffusion) up to 95% humidity, the rest sometimes up to 85%
		Dimensions: 156mm×109mm×59mm
		weight: 0.42kg
		Installation, easy maintenance, with dust, moisture, water, anti-demolition, to prevent man-made damage and other functions.
