A 0.93 - 0.95 power factor input under all load conditions with low standby power consumption
Automatic power control to within ± 2% of rated output while accepting input voltage fluctuations as per supply requirements section
High inverter electrical efficiency of up to 90%
The unit accepts standard 3 phase supply obviating the need for special supply transformers
Heavy duty 3 phase AC to DC rectification with capacitor filtering.
Simple stable DC link - ensures smooth firing of SCRs
No high frequency contractors - induction load is energised by solid state SCR / Diode inverter system. Circuit isolation by output transformer.
low maintenance costs - there are minimum moving parts to wear out
Variable frequency - it follows load variations and automatically adjusts itself to maximise power without capacitor switching.
Fast electronic fault protection backed up by high speed fuses.
in-rush currents are minimal on start up.
Continuous or frequent stop starting at 100% power harmless to equipment. Unit is capable of operating continuously at 100% power or alternatively unit can be switched on/off under full load conditions.
