3.1 System architecture
The DPA UPScale ST S2 System has a decentralized parallel architecture (DPA). Each DPA UPScale
module has its own:
- Rectifier and inverter
- DC booster
- Static bypass
- Battery connection
- Control logic
- LCD control panel
Fig 3.1-1: System architecture
Therefore, the UPS does not have common components. This offers high availability and no single
point of failure.
There are two types of DPA Upscale modules, as follows:
Module type UPScale M 10 UPScale M 20
Rated output power 10 kW 20 kW
Weight
18.6 kg 21.5 kg
Dimensions
(WxHxD)
488x132x540
The DPA UPScale Modules are “safe-swappable” - no disturbance to the operation of the load is
caused by inserting or extracting a module from a system while it is powered.
