Active Power CLEANSOURCE® PLUS SMS
CLEANSOURCE® PLUS SMS is Active Power's stand-alone single-module system. It succeeds the CleanSource 300 Norwerk showed previously and is used where one or a few parallel modules cover the need.
- Mid-size data centres and server rooms
- Industry and broadcast
- Healthcare (seismic certified in the US)

Technology
How it works
The flywheel stores the energy and a fault-tolerant IGBT architecture protects the load. The energy is sufficient for diesel starting and synchronisation – also when gensets are paralleled.
Without batteries, space and weight are saved, site testing is simplified and there is no routine replacement after a few years.

Application

Service
Operation and maintenance
Same service concept as the rest of the CleanSource family: annual check-up, bearing changes at fixed intervals and no batteries to replace.
A rotary plant should always be load-tested at commissioning – stepped load, utility failures and transfer to engine.
