Socomec Sicon MODULYS 4500 UPS Repair
« on: June 30, 2017, 05:31:47 am »
Hi Guys,

yesterday i picked up an old ups from dumpster. It´s Socomec Sicon MODULYS 4500 VA model. I connected mains and 4 SLA 12V 7.2Ah batteries in series, so input voltage was about 52V DC. Nothing happened. I opened it and checked for burned components and i found nothing. There are 3 1500VA modules, a main board, and one board where is everything connected. Also on that board there are two flyback psu, one is mains powered, and it is working, i can measure 15V on output, and there is another one battery powered, and that one is dead... no output voltage, no voltage on the UC3845... Also voltage regulators on main board are not recieving power... SMTP module is also dead, no input power... I saw only one fuse on board, for the mains powered psu... There is no fuse for battery... I found similar ups, only weaker... have similar board only 2 inputs for modules...

Any help is more than welcome.

Check the batteries, are they dead? can they light up a car light bulb? If they cant then their dead.

Check the main input power, follow the PCB, check the input filter all the way to the storage capacitors.

Check for blown transistors, fuses to the batteries, control signals...

Post pictures to get a better view of the device's PCB.

The simple fixes are the best fixes!  :-+

Try finding the user manual for the UPS and see if it has a chapter on how to setup the UPS via network. Maybe a default adress or a direct connection to configure it.
