SMART VT 10 internal fault

[BillP]

Hi Engineers

Kindly may I ask your opinion to the following:

We own about 7 or 8 APC VT between 10 and 30 KVA and we are facing a lot of problems regarding to Power module faults. 5 Units are already faulty. Nobody repairs this UPS. Most of the UPS when faulty after a brown-out or site wiring faults.

Furthermore, we have about 10 UPS Smart RT 5 kVA and there are running at the same site as the above mentioned UPS without any problems.

Kindly, I would like to know the following:

1^st  Should I move to other brands of UPS and leave APC a part?

2nd Is it true that APC does not allow their technical support partners to repair APC VT Power modules.

3^rd What is the cause of the VT powermodule faults, when other UPS continues to work in the same building and the same energy source.

Kind Regards,

Boris

Hi Boris,

Power Modules in the VT units are not repairable as with most of our units.  There are many possible reasons for possible power module faults so it is extremely difficult to answer these questions.  While I am not 3 phase support, I would strongly advise you to call into 800-800-4272 to speak to an Engineer who is experienced with these units to go over these issues and weight out options.

Regards,
