BR1500I overload led blink - internal fault

[Anonymous user]

Hi, I connected 2 power strip with a switch to my ups.
A power strip power router and PC. The other power monitors and various accessories.
Sometimes the UPS goes into alarm when I turn the power strip on, but after a few seconds resumes normal operation.
This night, however, has triggered the breaker went out the electrical system and all equipment. From that moment marks the UPS overload remains constant even unplugging everything except the main power cable. Disconnecting the battery rightly points out that it is not present but reports linking it back overhead.
This type of problem seems common and I would like to know which component is replaced (or other relay or MOSFET).
I opened the ups and there are no signs of burning.
How can I fix it?
Thank you.
p.s. I am Italian and use google translate.

The fan work fine. Even the 3 relays work well. Remain the MOSFET and any SMD components.

It Could Be A Fan Fault

Ya I Don't Know For Sure But The Overload Flashing Could Be That The Ups Was Permanently Damaged From An Overload 😞
Is The Transformer Ok??
Otherwise We See A Lot Of Fan Faults That Cause The Overload Light To Blink

Fan and Transformer are ok
Even turning on all the equipment consumption does not exceed 400W
There may be peaks when active sockets of three monitors / PS3 / audio / accessories but they last less than a second.

Hook It Up To Powerchute And See What It Has To Say

Warning overloaded. Load 0. Autonomy about 700 minutes.

well if it says its overloaded at 0 watts the firmware seems to be corrupt

how can I fix it?

Hi Master,

Aside from the Overload LED flashing, any other LED that is lit up?

[BillP]

I Dont Know If You Can You Would Have To Reprogram It

no

Looks like your UPS can no longer be repaired.

I think too. For this I buy a SMT1500I 🙂
