UPS Services - Uninterruptible Power Supply Services

UPS Services - Uninterruptible Power Supply Services

Just installing a UPS does not automatically guarantee success. Batteries and fans can fail, runtimes diminish, loads change, and systems can get stuck in static bypass mode. The UPS is not a fit and forget item. Failures are often discovered just when you needed it to work, with possibly disastrous consequences.

This will ensure that your system is working reliably and efficiently, and let you know if any action is required to guarantee uninterrupted power. Or perhaps you are looking for a new UPS system or upgrade? APTC also provide full Uninterruptible Power Supply Services and Management solutions.

UPS Battery Replacement

The most popular batteries in the UPS industry are valve regulated lead acid batteries (VRLA) which utilize an absorbed glass mat (AGM) separator technology to immobilize the battery electrolyte.

There is never any need to add water to the cells and in fact all vents’ are factory sealed. Since these batteries are low-gassing they require no special ventilation.

These batteries are the ideal choice for UPS Systems, emergency lighting Inverters, switchgear and other standby applications which need reliable, high rate power.
