Question about Belkin (F6C800-UNV-PL) UPS System

1 Answer

Trouble shooting UPS

My UPS autometically converts itself to UPS function even when the main supply is on. IF the UPS is moved a little bit it is OK. After some time it again gives the problem. Its variables have been cleaned with thinner.Can you guide me about the fault and the remedy.

Sounds like you have a cold solder joint somewhere on the PC board.

I would pull the PC board off......before you do that. May I suggest you take a digital picture of it before you take it off so you know where all the wires go. Flip it over and touch a hot solder iron over verious areas you might suspect that you have exposed or cracked joints.

My inverted goes to battery mode even when mains supply is ok.then it will come back to normal mode again and run of mains.what is the solution


If this happens repeatedly and doesn't stop for 10-30 minutes... then you have a bad inverter. Price of repair compared to just buying a new one are about the same.

Remember, it's not just sags in current that activate the UPS, it's also spikes... and if you're getting many of those in a short time frame then the UPS is doing it's job.

UNINTERRUPTIBLE POWER SUPPLY


UPS – UNINTERRUPTIBLE POWER SUPPLY
Uninterruptible power supplies provide protection against mains power faults to computer equipment.
These faults include voltage spikes/interference, over voltage and under voltage, mains supply interruptions and surge protection etc.
These faults can cause computer and electronic equipment that are connected to an unprotected mains supply to malfunction and/or sometimes fail.
A common problem, when burning Cds, DVDs etc. any slight power interruptions to the burning process will halt the recording process and rendered the disc useless.

There two type of Uninterruptible Power Supplies
The lower powered and cheaper type UPS are switch-over types, when the mains supply fails, the UPS switches over to the batteries and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.
NOTE : The mains waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).
The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and then the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

UPS - Battery Fault


UNINTERRUPTABLE POWER SUPPLY
Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. Including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault. A faulty charging circuit will not charge the batteries and will also cause a fault condition.

Can i have all the basic details of UPS system


UPS come in two types, lower powered cheaper types are usually switch over power.
These units senses a power outage and then switch over to the battery power to generate mains supply. The switch over occurs in milli-secs and does not affect the computer.
True UPS types constantly run off battery power to generate mains supply so there is no switch over time lag. These units are higher powered and higher costs units.

Both type of UPS have the same components.
Battery charger.
Batteries
Inverter that converts battery voltage to mains voltage
Electronic controls

Ups starts beeping


Is there any indicator lights ON showing the fault condition?
This could indicate that the battery has a low charge. Even if you switch off the mains supply and it switches over to the battery, the UPS may shut down after a short time as the battery power (charge) runs out.
If the battery is more than 3 years old then it may be due for replacement.

My ups is switching off itself immediately the mains goes off.the battery is okay with 13v.

These lower powered and cheaper KVA type UPS are switch over types (when the mains fail, the UPS switches over to the inverter in milli-seconds to supply mains power). It is a possibility the inverter circuit is faulty and when the mains power fails the inverter does not switch over.

The true UPS type are usually the higher KVA units (over 1500 KVA units) that converts mains power continuously via the inverter circuit. The mains power charges the batteries and the inverter drawing power from continuously from the batteries (therefore there is no switch over time lag from the mains to the battery.

Dead appearing ups/inverter


keep on your main switch. off all the lights fan and other electrical items, let that inverter get charge first

UPS problem


Hi,

Based on your post/description, two (2) possibilities:
1. electronic fault - main power/AC mains sensor which could be really just a relay; or
2. corroded fuse terminals or fuse holder.

The first is a bit of a challenge since different brands/models have different sensing circuitry design. Some can be as earlier stated, a simple AC relay while others could be a TRIAC switch with a DIAC trigger. Still, some could be an elaborate AD converter and a myriad of logic circuitry. Often, a service manual or at least a schematic diagram would be needed, however these are not that readily available and most often the tech or DIYer must resort to winging it. This of course would require familiarity with electronic circuitry and components, use of a DVM and a soldering iron. Extreme caution must be exercised since even with 12VDC supply most of the electronics are at least at 60VAC+ level.

The 2nd possibility would be of course be the easiest to determine and repair. Replace/clean.

Should the downtime & repair cost makes the project no longer economically reasonable, perhaps your best bet would be to simply replace the UPS since their prices are relatively low.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
