Founded in 1988, Dalian Scientific Engineering Electrical Devices Factory has engaged in electric products combined with electric power and electron for the past decades. Through tough works and continuous innovation, we gradually become a professional manufacturer intergrating research, design, produce and sale and obtained ISO9001:2000 quality management system certification.
Confronted the fierce competition, our staff adhere to the principle of high-tech, high starting point and high market and develop successively JHQ1, JHQ2, JHQ3 series a-c motor non-contact constant current starter, JMW1 series full automation microcomputer illumination voltage regulator, JMK3 computer controller for street lamp illumination, JZF series high-power parameter compensating voltage regulator etc., which received a favorable social and economic benefits since its launching into market. These high-tech products are widely used in industrial and mining industries, railway, seaport, scientific research, hospital, university and hotel etc.
JHQ series a-c motor non-contact constant current starter acquired a patent letter (patent No.ZL942170114) by the State Patent Office in early 1995 and was listed as the best choice products by Dalian Electricity Office. Its functions of non-contact, soft-starting, soft-stopping, non-phase and overcurrent can realize random following detection adjustment with full-automation closed loop which assures a best start force when running with loads and standardized distribution technique on soft starting devices for firefighting use.
　　JMW1 type illumination voltage regulator fully controlled by microcomputer is developed by us through combining foreign new technologies and power supply situations of street lamp illumination. In 1996, cognized as the state level new technolgy and excellent product, this product enjoyed a high reputation among users and widely used in illumination projects of Dalian government. The new type semiconductor power module, high integration electron stabilized voltage circuit and intelligent swith controlled by microcomputer truely realize non-contace, soft-starting and prolong the service life of lamps with stable output voltage, which invariable the idealest product in street lamp illuminating system.
　　JMK-3 type street lamp switch controlled by microcomputer developed by us is a kind of mating products to JMW1 type high-power illumination voltage regulator and also can be used alone. This product opened a leading card of applying microcomputer technology in street lamp switch controlling system. Time difference parameter of sunrise and sunset of all year saved in the computer, therefore, switching time can be automatically adjusted according to different sunshine time; power-cut protection and lightning protection can protect your data from losing after turning off power in ten years. When mating with JMW1 type high-power illumination voltage regulator, it also act as a street lamp power integrating illumination, voltage regulating and automatically controlling.
　　JZF series AC parameter compensation electric voltage regulator is also one of our leading products which overcomes the deficiency and defect of domestic voltage regulator and realizes non-contace switch during the whole voltage regulating major loop and realiable power supply full-automatically. With its high stabilizing precision, wide rangel, sine wave output and lift pressure compensation full-automatically, this product is widely used in industries.
In a word, high quality, integrity ethics and meticulous services are our persistent guiding principles.
With our quality, complete and strong products, we sincerely welcom cooperations with you!
