1.JJW SJW A.C. Precision Purity Regulated Power Supply Feature
A.C. Precision purity regulated power supply is our new, high characteristic electronic A.C. regulated equipment as KUPA doctor’s theory, combining Asymmetrical Digital Subscriber Loop colander net, which integrates multi-functions such as purity regulation and anti-disturbance. They are of wide range in regulation, fast speed in response, high precision in regulation etc.,to refrain all kinds of noise from power net and disturbance from peak. They are your first choice among of A.C. regulated power supply at present, which are 614 series electronic A.C. regulated power supply and ideal substitution regulated power supply.

It often happens that the electrical equipment are damaged because of lack of power. The experts of power point out most 80% malfunctions of computer are caused by A.C. power supply directly or indirectly. So as to ensure the safe operation of electrical equipment, the power supply must be improved. Our products fulfill the requirements in such places for his spurious characteristic. Our products are suitable for the following fields: science department, university, corporation, hospital, broadcasting station, communication equipment, traffic system, test equipment and all automatic production equipment.

2.JJW/2 A.C. Intelligence Percision Purity Regulated Power Supply Feature
JJW/2 A.C. Intelligence precision purity regulated power supply is new high characteristic electronic A.C. regulated power supply,which is one of advanced characteristic A.C. regulated power supply at present, and widely suitable for high precision electrical equipment and general electrical power equipment. In America, the products have been used into military and aviation etc. JONCHAN A.C. intelligence precision purity regulated power supply adopt advanced technology, integration purity, regulation, anti-disturbance and automatic protection etc. with the advantages such as wide range in regulation, fast speed in response, high precision, anti-disturbance, low distortion, strong capacity in anti-load impact, long life, low noise and so on .
