APC UPS Red Light Inverter Fault

The APC Smart UPS range has been the most commonly selected choice of UPS for IT managers for many years. For good reason, the UPS will often operate without fault continuously for so long that owners may even forget it is installed. Unfortunately, when users forget, trust and leave the UPS without replacement batteries, servicing or a UPS health check the APC Inverter Fault light may suddenly appear.

This is also known as the APC red light of death and usually results in loss of output and power to the connected load equipment.

In this situation the battery level lights will illuminate in such a manner to display a code so that that the exact kind and cause of the inverter fault will be apparent APC, however this information is useless to a user as a repair to this inverter fault requires board level component repair or internal PCB replacement.

In order to get the load powered and protected again the UPS must be bypassed or replaced while the faulty UPS is diagnosed and repaired in a laboratory environment.

If you have an APC Inverter Fault or are seeing the APC red light of death, contact UPS Power Services for emergency assistance, we can immediately:

  • Provide telephone technical assistance and diagnosis
  • Despatch an engineer or electrician to site to assist in restoring power
  • Despatch an emergency APC UPS from our stock as cover
  • Provide diagnosis and repair for your faulty APC UPS

{UPS Power Services have extended the life of our UPS by providing maintenance when APC would not. Bought new batteries from them at a reasonable price which they installed and took away the old ones. Have also had our first annual service check which gave a detailed report on the UPS. Both employees who have been to our offices have been polite and carried out the work cleanly leaving everything as it should be. Only in our first year with them but from our current dealings seem an honest company wishing to give good service with satisfied customers.
IT Manager
{With UPS Power Services, we've recently just completed a project to install a UPS solution that covers our entire IT infrastructure. The team have been fantastic from the initial scoping/quotation phase, through to installation and then with any after sales support. I honestly couldn't ask for better service, and I would highly recommend them!
{UPS Power Services supplied our business with a temporary UPS when our ageing old system broke down, the staff attended site to asses the type and size of UPS required with in 4 hrs of my 1st call to them. they then installed the temp system so that we was safe with our back up procedures. We was then quoted for a new system to replace our broken system. Through out the whole procedure UPS POWER SERVICES portrayed them selves in an excellent professional manner from start to finish of the project. I would definitely recommend them.
{Best compliments to UPS Power Services for their professionalism, effectiveness, great and polite communication. Cannot recommend them enough. Thank you Mark and team!

{We had a very old UPS unit in our server room which urgently needed attention. Ian and the team at UPS Power Services were superb. They did everything they promised, turned up when they said they would and got our UPS back up and running within 24 hrs of the diagnosis. We will happily be using them for all our UPS requirements going forward.

The job hasn’t been fed up the ladder (Department/Estates) yet but I can say we are extremely grateful from the professional job received. I’ll be back in touch very soon.
