 | Shanghai Jinling Co., Ltd. | | Product Detail | Three-phase watt-hour Meter in pulse series | Description:
| Product Class : Electronic Instrument·Electrician Instrument
Three-phase watt-hour meter in pulse series has series DM9 and series D86YM/M (active/passive) pulse meter,they are improved on the basis of three phase watt-hour meter in D86 series and class 0.5 three-phase meter which securely fixed by energy pulse transformer and output circuit as well as the combination of sensor,electronic technic and traditional inductive meter.The product has been widely used as the signal source or data stream in the area of energy data-sampling electric loading controller,electricity management etc..The product is manufactured according to the standard of JB/T7655-1995.<<Watt-hour Meter in Pulse Series>>
Construction and Feature
This type of meter is improved on the basis of three-phase inductive meter,which integrates infrared sensor,amplifying circuit,pulse output circuit with low-resistance into a module with the feature of sententiousness and can be directly connected to RTU.
The pulse-sampling sensor of DM9 series is photoelectricity echo type,of D86YM/M series (including type DS42YM/M)is electromagnetism induction type.
Three-phase pulse meter adopts photoelectric coupler output with strong anti-interference and can be made of voltage output too.
