Question about Mustek (MUSTEKUPS600) UPS System

1 Answer

Powermust 600 Plus doesn't provide power

When I turn it on, Led does not light, there is a permanent sound coming from device, and there is no electrical power provided from the unit. All of it is being happened while the unit is connected to an electrical power source. When it should provide power by it's own battery, nothing happens.

My numeric 600 plus ups swithched off automatiocally when power goes off not a single second back up its provided


Did it work before?

If so, then it has developed a fault. Check the battery fault light on the UPS panel. Perhaps it's battery is dead, or batery charging circuitry is faulty. Anyway, it would most probably need professional attention by a serviceperson.

If it did not, double check whether you have connected the computer etc. to the proper sockets - many UPS devices have a couple of UPS-powered sockets plus additional sockets with surge protection only (no UPS power!) for high power devices like laser printers etc.

Did you read the manual for your UPS ?
I read it - there was something about lamp ledding - different ledding of lamps and different frequncy of noisy sound can mean different problems - try read manual.
I think, your description means that you need to change battery.
Battery work 2years +- .

I take the 4 screws out of the bottom of the Powermust the unit opens but appears to be hinged at the back so I can't get access.


You don't need back side.
The battery locates at the front.
Carefully get out forward case (with button), and you will get access to battery.

In my home, it was a fault in ilumination and the UPS isn't ringing but is always with the red light on What can I do? PS: Sorry my english but I am portuguese


The red light means that it is being discharged or is low on battery power/it's not recieving power from the wall plug. Maybe the UPS needs to be charged. While the power is on at the wall plug, switch off the power to the UPS then you should get an orange light showing that it is being charged. Switch off your computer for a while, aftyer about 12 hours it should be fully charged.

Your rating of this solution is much appreciated.
Thanks.

I have changed the backup battery, i have charged it for about 22 hours, but when i turn off the electrical supply, it goes off! ( the ups) MUSTEK POWERMUST 800


Remove batts, Check battery connector, fuse and batt volts, if you have dummy load (car headlight etc) check batts are working and measure voltage under load.

Also check if UPS needs to be told there are new batts read manual or check support for maker.

Let me know what you find, hope this helps

UPS does not provide output power to outlets when turned on.


Hello

I've never seen a schematic for this. It's difficult to diagnose online but I would look at the primary circuit before the inverter. Possibly one or more bad caps or the inverter itself. Good Luck

Powermust 600 USB 5 minutes shuting down problem


Load is the problem. Too low load on UPS will cause that on almost all Musteks.
