Piller DeRUPS™
In a DeRUPS™ layout a diesel genset – upstream or downstream of the UPS – is integrated into the controls of a UNIBLOCK™ UBT+. It behaves like a DRUPS, but UPS and genset are physically separate.
- Complex designs such as IP systems
- Retrofits reusing existing gensets
- Sites with both short-break and no-break loads

Technology
How it works
The flywheel energy store ensures a seamless transition between genset and UPS while the controls coordinate start, synchronisation and load transfer.
Because UPS and gensets are sized separately they can be extended independently, and the load can be fed from the gensets while the UPS is in maintenance. With a sync box, parallel engine groups start as fast as single modules.
Application
Where it fits
- Complex designs such as IP systems
- Retrofits reusing existing gensets
- Sites with both short-break and no-break loads
Versions and options
- IP bus
- Medium voltage
- Sync box for parallel engine groups
Service
Operation and maintenance
The separation improves resilience during maintenance: genset and UPS can be serviced separately without taking the whole supply chain down.
A rotary plant should always be load-tested at commissioning – stepped load, utility failures and transfer to engine.
