Fuse apx200m


HI,
If the fuse is blowing of then there is problem with the inverter stage of amplifier. There is an inverter stage in the amplifier to boost the 12V to + or - 30 to 40V normally. Its a switching circuit normally uses Mosfets and ferrite core transformer and a driving IC. If the mosfet is shot then the fuse will blow off immediately after power is connected.

Check on thing remove the REM connection and then connect the power. If the fuse blows the there is fault with the Mosfet Its short.
If the fuse blows only when you connect the REM then the amplifier stage is faulty.

Also check by disconnecting the speakers. if any of the speaker is faulty then there is a chance for fuse blow off.

My inverter keep blowing 40 amp fuses without load


Hi Trevor,
A 1000W can barely supply 5A at 220V, less than 10A at 110V. So if a 40A fuse blows, there is a serious problem and you should not attempt to use this unit after it has been checked by a qualified person. Please be careful!

Good luck!

My name is Gena. The VEC024B that is being used by our field technicians are having problems with the fuse blowing in their work vans. Their vans are equipped with laptops.


Hi Gena, the inverter is a 400 watt unit. This is not a rating for a continuous load. You do not mention which fuse is blowing. This could be the fuse in the inverter or the cigarette lighter (power source) fuse. In either case, a fuse blowing could be a short circuit, something in the inverter shorted, or too much load. I am going to look at the too much load side of things. Not knowing how many laptops are being used, with the inverter if you have a 20 amp fuse in the cig lighter, this will allow you 20 amps X 12 volts = 240 watts. I would not run the inverter over 240 watts because of overheating issues. So, 240 watts will run 3 laptops. Just the laptops. Most laptops draw around 70 watts. check your power supplies on them to find their rating. If you exceed the 240 watts by combining the ratings, then you can expect trouble with your inverter. It will give 400 watts, but this is a temporary condition only. Another inverter will be needed or a larger one installed and it being connected directly to the battery (with a fuse of sufficient size installed). You could also (let us say there are 6 computers) charge and run 3, and the other 3 are running on their batteries. After an hour, switch so that the 3 running on batteries now are charging as well as running. The other 3 are now charging.
I hope this helps. If you have any other questions please provide additional information. Such as the size and location of the fuse blowing. The laptop power supply ratings.
thank you

My 400 watt inverter will not charge my laptop the fuse keeps blowing?


Your laptop PS has big condensers in the input. Even supplied by mains through 6A quick fuse or automatic breaker it will drop first time, but may hold the second. Your inverter may be has fast fuse 2 - 5 A. If not so fast it may carry the initial load.

Hint: If you are not "both left handed" you can connect  20 - 200 Ohm (2 - 10 W) resistor in series to your Laptop Power Supply. After the initial start of the inverter you can shorten the resistor by a 3 - 5 A switch.

When I turn microwave on it blows 60 amp fuse


60 amps times12 volts = 720 watts times 80% effic of conv. = 576 watts available for microwave...

You must have a very tiny microwave as most require at least 1000 watts input power. That might have something to do with blowing the fuse. Since the microwave has a very reactive inout, you need a goodly safety margin above the rated watts input.

Fuse missing


I would start with a 1.5 AMP fuse (175 watts / 12 VDC = 1.6 amp)
Make sure the fuse is rated for at least 120 VAC. Hope this helps!..Gary
