Secure, clean and reliable power
The NO-BREAK E1 is a Dynamic Uninterruptible Power Supply system used to secure and protect critical equipment from utility disturbances and outages. The Dynamic UPS is manufactured by EURO-DIESEL S.A. with over 20 years experience in this field, EURO-DIESEL and E1 DYNAMICS are teamed to provide you with the most efficient, and cost effective solution Designed with You In Mind!

The Kinetic Energy Accumulator - ACCUROTOR consists of two rotating parts, the outer rotor, (orange colored picture) which rotates around the Main Rotating Shaft.

The inner rotor, driven by the central shaft fed by utility, rotates at 1800 rpm (60 Hz). It is provided with two sets of windings: an AC winding and a DC winding as part of the Brushless Exciter.

In Conditioning Mode, utility is present, the NO-BREAK E1 acts as a synchronous condenser (motor load) and provides power conditioning by regulating the output voltage, power factor correction, harmonic distortion filtering, and also protects against spikes and other anomalies. In this mode, the Outer Rotor is maintained at full speed 3000RPM by control of the Brushless Exciter.

In Emergency/Diesel Mode, when a utility failure occurs, the stored kinetic energy from the outer rotor of the AccuRotor is retrieved by means of the Brushless Exciter, and transferred to the drive of the synchronous machine. At this point the machine is now operating as a generator. This occurs without any interruption for the user.

Shortly after the utility failure, the diesel engine is started and coupled to the drive of generator by closing the electromagnetic clutch. At this point, the Engine continues to drive the generator providing complete uninterruptible power to the loads.
