UNIBLOCK UBTD - Rotary Diesel UPS from 400 kVA up to 3000 kVA
The UNIBLOCK UBTD Diesel Rotary UPS combines all the benefits of a rotary UPS with a Diesel engine in one integrated unit. The system consists of the UNIBLOCK motor-generator connected via a clutch to the Diesel engine, all mounted on a single short base frame. The load is normally fed via an isolating and coupling choke connected to the utility supply. The choke has a second tapped connection to the motorgenerator.
In the event of short interruptions or complete outages, the load is supported initially by a short-term ride through source which can be either a conventional battery system or a Piller Powerbridge (kinetic energy store device). This option is unique to the Piller system. With the load safely supported, the Diesel engine is then given a command to start,and once fully up to speed, it takes over the long term support of the load by engaging the clutch seamlessly.
