The KOHLER PW 9500DPA boasts a highly competitive total cost of ownership through a combination of energy efficiency, scalability, ease of servicing and advanced functionality modes.

For example, while system energy efficiency of up to 96% significantly reduces running and cooling costs, and thus an organisation’s carbon footprint, further energy savings can be made by operating the KOHLER PW 9500DPA in Xtra VFI mode (switching some modules into active standby when loads fall) or more traditional Eco-mode.

Within a frame that has remarkably low footprint for its power, the UPS system can be ‘right-sized’ to optimise the power required to match the initial critical load and modules can be added incrementally as the load increases. This means that you only power and cool what you need, saving power usage over the life of the UPS.

Additionally, KOHLER PW 9500DPA has a near unity input power factor at full load reducing the size of the input cable and fuses, thereby saving on materials and costs. Input current total harmonic distortion (THDi) of less than 3.5% virtually eliminates harmonic pollution on the mains supply. This saves unnecessary over-sizing of gen-sets, cabling and circuit breakers, avoids extra heating of input transformers and extends the overall lifetime of all input components.

Hot-swappable modules

True ‘hot-swap’ modularity enables the safe removal and/or insertion of UPS modules into a KOHLER PW 9500DPA system without risk to the critical load and without the need to either transfer the critical load onto raw mains or remove power from the critical load.

Industry-leading energy efficiency

With an online energy efficiency of up to 96% and up to 99% in eco-mode, this is one of the most efficient uninterrupted power supplies on the market.

Xtra VFI mode – efficiency even when under-loaded

The KOHLER PW 9500DPA features Xtra VFI mode – a smart way to minimize losses and improve efficiency when running in double conversion mode. With Xtra VFI mode enabled, the UPS automatically adjusts the number of active modules according to the load requirements. Modules that are not needed are switched to standby but remain in a state of readiness, primed to kick in and transfer to active mode if the load increases or the mains fails. The efficiency improvements are highly significant when the load is less than 25% of full capacity. Find out more and see an example.

Modular scalability

100kVA modules can be added and removed with no risk to the critical load and no downtime. A truly future-proof UPS system offering horizontal and vertical growth to a maximum of 3MVA.

Six-Nines (99.9999%) availability

Advanced decentralised parallel architecture and parallel redundancy provide ‘six nines’ availability with no single points of failure even during UPS maintenance.

Advanced Decentralised Parallel Architecture (DPA)

Decentralised Parallel Architecture (DPA) means each UPS module contains the hardware and software required for full system operation. They share no common components so a DPA parallel system offers extremely high availability. In addition, potential single points of failure are eliminated and system uptime is maximised. UPS modules can be paralleled to provide redundancy (parallel redundancy) or to increase the system’s total capacity.
