Active Power CLEANSOURCE® HD
CLEANSOURCE® HD is Active Power's highest power-density flywheel UPS. Active Power was acquired by Piller Power Systems in 2016 and is now part of the Piller group. It is the current version of the CleanSource HD Norwerk presented previously.
- Data centres with limited space
- Healthcare (OSHPD seismic approval in the US)
- Sites with a genset where a few minutes of ride-through is enough

Technology
How it works
Active Power's parallel online architecture provides good isolation between input and output and delivers a clean sine wave. The manufacturer states protection against all nine IEEE power disturbance types.
The integrated flywheel takes less than half the space of a battery-based system, and the energy is sufficient for diesel starting and synchronisation – also with paralleled gensets.
675 kW (60 Hz) building blocks can be paralleled up to 5400 kW.
Application
Where it fits
- Data centres with limited space
- Healthcare (OSHPD seismic approval in the US)
- Sites with a genset where a few minutes of ride-through is enough
Versions and options
- CSView software with over 200 telemetry points
- BMS integration via Modbus TCP or SNMP
- Dual input and integrated maintenance bypass
Service
Operation and maintenance
Active Power specifies a routine annual check-up and a bearing change every third year – and no battery replacements during the 20-year flywheel life.
A rotary plant should always be load-tested at commissioning – stepped load, utility failures and transfer to engine.
