Model Range - Kohler powerwave 8000dpa S2 ST-60 User Manual

• Wide UPS input voltage operating window extends the battery life due to fewer discharge cycles.
• Battery discharge protection caused by load jumps.
• Proactive battery protection from false manipulations and inadequate charging voltages.
• Proactive battery failure detection thanks to Advanced Battery Diagnosis (ABD) algorithm.
• User selectable battery tests.
• Optional temperature compensated charging to enhance battery life.

The PW8000DPA ST S2 is a truly flexible system based on 10kW or 20kW UPS power modules which are assembled in a
range of purpose-designed, free-standing cabinets containing up to ten UPS modules. The cabinet is rated according to
the maximum number of 20kW modules that it can house – i.e. 40kW, 60kW, 80kW, 120kW and 200kW (see Figure 2.1).
The 40kW and 60kW cabinets also contain the UPS batteries but these must be located externally in the case of the
80kW, 120kW and 200kW models. A range of matching battery cabinets is available.
Key Point: All the modules fitted within a cabinet must be of the same rating – i.e. it is not possible to mix 10kW
and 20kW modules in the same parallel system.
The illustrations in Figure 2.1 show the various cabinets fully populated; however each of the systems shown can operate
with as little as a single module fitted. Further power modules can be added to a vacant slot at a later time, without
needing to power-down the system or in any way disrupt the load. This 'hot-swappable' technology also allows individual
modules to be exchanged for testing or troubleshooting while the equipment is running without having to transfer the load
to the bypass supply – depending on prevailing system redundancy and load demand.
