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.

The outer rotor of the induction

coupling is re-energized. The

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.
