Precision Purifying AC Regulated Power Source

　　SJA series precision purifying AC regulated power source adopts the power regulation technology of sine energy distribution formula, which is advanced in the world and represents the latest development of AC stabilizing technology. Its circuit is composed of sine energy distributor and large power wave filter by paralleling. It has the advantages as high accuracy of stabilization,strong over-load capacity,High efficiency,successively working for long period and long service time,etc.It is an ideal replacement for the 614 series electronic voltage stabilizer and magnetic saturating voltage stabilizer, also it can provide a quiet and reliable working environment.
　　SJA3 series precision purifying three-phase AC regulated power source is composed by SJA series single-phase power source with "star-shaped" connection,so it possesses all the advantages of the single-phase power source. It is an ideal regulated power source for all kinds of test and measurement device,Electronic equipments in production enterprise, Research institutes,Medical and health fields.
Application
　　lt is suitable in computer network project,Electronic instruments,armarium,research institute,Measurement and test device,Factory test board and so on.
