1. High Efficiency : Output low voltage, high current, adopt IGBT switch mode power supply or thyristor double star circuit, high efficiency, excellent energy saving effect. 2. Complete protection measures, high reliability : Has output voltage limit, current limit functions, over voltage, over current, short circuit etc.protections, adopts software and hardware measure to improve EMC.Switch mode power supply adopts N+X parallel and reduncy technology, improves stability and reliability. 3.Inteligent : Adopts high performance DSP as control core to improve intelligence. 4.Good Adaptability : Switch mode power supply uses oil cooling, except the operation panel, all components are immersed in oil cooling, except the operation panel, all components are immersed in oil. Thyristor power supply's components have passed treatment of water-proof, dust prevention and anti-corrosion. The power supply has long lifespan. 5.Output waveform controllable : Output DC voltage or current waveform with acceptable ripple, or pulse etc. special waveform wit periodic reversing polarity or adjustable altitude, improves specific volume and corrosion efficiency. 6. Low Input current harmonics, high imput power factor : Adopts phase shifts, APF Technology, reduces input current harmonic content and upgrades input power factor greatly.
