APPLICANT
JJW precise purify ac voltage stabilizer with advanced electronics and information industry , the rapid development of micro-electronics technology and the wide application of electronic computers, inevitably cause pollution to power grid, leading some anti-jamming is a bit poor electrical equipment cannot run normally, purifying regulated power supply is the best solution.
Our company has set up a new single phase (JJW) three-phase (JSW) series precision purifying ac regulated power supply, it is integrated with voltage regulation, purification function 
and voltage digital display obvious, with wide voltage range, high precision, low noise, long life, high output voltage stability, reliability, and can work continuously for a long time and adapt to the nature of the load, and can effectively suppress the noise and power grid peak voltage.

USE OCCASIONS

This series can be widely used in testing equipment, automatic control system, communications equipment and other modern 
electronic equipment voltage protection, scientific research units, universities and colleges, industrial and mining enterprises, measuring, testing, medical, telecommunications and other preferred by the department of a new generation of regulated power supply.

USE CONDITIONS

JJW series voltage regulator should be used in indoor, when normal conditions as follows:
1, the ambient temperature: - 5 ℃ ~ + 45℃ degrees Celsius
2, altitude: not more than 1000 meters
3, relative humidity: 90% or less
4, the installation place should be no impact stabilizer of the insulation gas, steam, chemical deposition, dust, dirt and gas explosion and corrosive substances
5, installation site should be no serious jolt and shock 
if not meet the requirements of the special conditions of use, shall be in consultation by using unit and my company
