Diesel Rotary UPS (no-break KS) has been in market since 1989 and provides uninterruptible power supply system used to secure and protect the critical equipments from the mains / grid failure. Manufactured and tested in modern facilities, this provides multiple benefits such as No AC requirement, No power electronics, No need for battery banks, take care of harmonics generation, compact size, high reliability, small footprint, user friendly, easy maintenance and reduced voltage distortions.

What is DRUPS and how does it work?

In case of a power outage, the kinetic energy accumulated in the outer rotor or accu-rotor) supplies the load until the diesel engine is running at its rated speed. Within seconds the diesel engine becomes the source of power and this is how your critical loads are always fully secured. All this happens, without the slightest interruption or aberration to the load. The Kinetic Energy Accumulator At the heart of the NO-BREAK KS is its kinetic energy accumulator: a clever but simple system to store and retrieve kinetic energy. It consists of two rotating parts: the outer rotor runs mechanically-free around the inner rotor. The inner rotor, driven by the main shaft, rotates at 1500 rpm (50 Hz) or 1800 rpm (60 Hz). It contains two sets of windings; a three-phase AC winding and a DC winding.
