General The requirement for power supply reliability is growing, due to the increasing application of information and data carrier systems, text processing, automated production processes and complex data networks. Irregularities due to loading of the public power supply by major users, peak-time use or by lightning strikes cannot be avoided. The result is: Mains voltage breaks, spikes and transients. (Fig. 1) Static UPS’s are being installed increasingly for loads that require AC voltages unaffected by interference on the mains e.g. • Data processing installations • Process control computers...

ENERTRONIC I an uninterrupptible power supply Function The static UPS not only has the task of supplying the connected consumers continuously and without interruption, but beyond that to also provide a clear improvement of the voltage and frequency quality in relation to the normal system. In normal operation the load is supplied by the input autotransformer, rectifier, inverter and output transformer route. The ENERTRONIC I is designed to meet the highest UPS classification VFI SS 111 in accordance with EN 62040-2. Rectifier The rectifier consists of an IGBT bridge with power factor correction...

Internal manual bypass Each UPS is equipped with a maintenance bypass with manually operated switch. When operated, the ENERTRONIC I is completely disconnected from the load. The supply to the load is now directly from the mains via the manual bypass. (Fig. 5) ENERTRONIC I multi utilities Parallel Operation For redundancy or increased output power, up to eight ENERTRONIC I units can be connected in parallel, operating an active load-sharing mode with active and passive master. Half load parallel operation is achieved using two separate bus bars, connected with a coupling switch. The state coupling...
