Ce 26 février, le label « Partenaire opérationnel 2014 » a été remis aux 50 entreprises, dont EURO-DIESEL, qui participent au programme E=MC² qui est mis en place par la Cité des Métiers.
The Police Investigation Bureau (Polizeiinspektion Düsseldorf) has awarded EURO-DIESEL GmbH as the winner of turnkey UPS solution provider for their facility in Dusseldorf, Germany.
EURO-DIESEL launches the next generation diesel rotary UPS system [+]
Many industries have a combination of critical (UPS) and non-critical (SB) loads in their facility. The NO-BREAK E1-SB is the perfect match to combine both load types by powering the critical loads at all times, and then powering the non-critical loads within a maximum of 10 seconds break.
The NO-BREAK E1-SB eliminates the need of additional diesel generators, saves on floor space and eventually, saves on building costs. As a result, this reduces the total Cost of Ownership.
The critical loads (UPS) are fed via the conditioned power of the DRUPS: Q2 is closed.
Non-critical (SB) loads are fed direct from the utility: Q5 is closed and Q6 is open. When a utility interuption occurs the breaker Q5 opens and within a maximum of 10 seconds, Q6 is closed to provide power to the non-critical loads via the diesel engine.
On mains failure, the critical loads are automatically protected at all times.
The introduction of a tapped choke in the electrical scheme provides an additional advantage: in case of a short-circuit on the non-critical busbar, the critical load will be unaffected since the choke will reduce the influence on the critical busbar.
Note : It is recommended that for all NO-BREAK E1-SB systems, the critical loads be larger than the non-critical loads.
Output power split example (in 60Hz):
1. UPS Critical load = 1500kW, total output power = 2000kW. Therefore the rating is 1500/2000kW.
Note: The above systems are also available in medium voltage.
