Ask the Experts – Episode 2 featuring Louis McGarry

Keen to hear the views of his team members, Louis McGarry, Sales and Marketing Director, puts them into the hot seat to talk about the modular concept and true modular UPS technology.

A true modular UPS is where several individual UPS modules are contained within a frame. All the individual modules are UPS’s in their own right, all containing a rectifier, inverter and static switch and all operating online in parallel with each other. For example five 60kW UPS modules may typically be contained within a single frame offering a resilient configuration of 240kWs N+1.  If required, it takes moments (around 30 seconds) to ‘hot-swap’ a module while the rest of the modules continue to protect the critical load. At no point does the system need to be transferred to maintenance bypass and hence on raw mains. 

With a true modular system, where the static switch is included in each module, the rest of the modules in the UPS frame continue to protect the load until it can be replaced. This increases the level of availability dramatically.
