Four basic principles (1)
Simple, sure and reliable Rotary UPS/CPS concept invented and patented by Hitec
Power Protection in 1969
Rotary UPS/CPS = static UPS + standby generator
Fewer components than static UPS
Smaller footprint than static UPS
Easy installation & operation
Long lifespan (>25 years)
Line-interactive system
Rotary UPS/CPS run in parallel with utility power
Life-guarding mission critical processes
No power conversion
Four basic principles (2) Active filter (choke coil + generator)
Compensation utility voltage deviations
Filtering of utility borne harmonic voltages
Filtering of load borne harmonic currents
Power factor improvement (>0.98)
Environmental friendly system
Most energy efficient UPS/CPS system
Use of stored kinetic energy
No batteries required, no chemical waste No conditioned battery room required, saving space and energy
for ventilation and cooling
Lowest Total Cost of Ownership (TCO)

Power problem - Q1 opens, energy
from the inner rotor goes via the
generator to the load. The diesel
engine starts up and takes over
the power supply.

Utility power is back and after it
has stabilized the UPS/CPS
synchronizes and closes Q1. The
diesel engine ramps down and
the free-wheel clutch disengages.
