What we protect

Behind every Numax system
is something that can’t stop.

We don’t start with a catalogue. We start with what’s on the other end of the cable, and size, install and look after the system for that.

How it works

The best outage is
the one nobody notices.

This is what a Numax system does at 2:14 in the morning, while everyone else is asleep.

The grid fails.

A block goes dark. Lights, lifts and air-conditioning stop.

Your Numax UPS takes over.

In less than a heartbeat, clean battery power reaches every critical load. No flicker, no restart.

Nobody notices.

The surgery continues. The transactions go through. The servers keep serving. That’s the whole point.

And if you ever need us, we pick up.

Day or night, a Numax engineer answers, not a call centre, and the team from your nearest centre is on the way.

Why we do it this way

Built by an engineer
who still takes the call.

Our founder, P. Boopathy, is a service engineer at heart. In the early days he built each UPS by hand, drove it to testing and got home after midnight. Eight in ten failed those first tests. He started again every time.

“If a customer is waiting and no engineer is free, I’ll take the flight myself.”
P. Boopathy, Founder & MD Draft · to approve with Mr. Boopathy
