50 volt regulator

Ive had my amp for about 7 months bought it brand new.. its a 200 watt power acustik amp and i only have it running my highs at the moment.. it has power going to it grounded well and fuses r good. it started when for a few days it would have sound and then not have sound.. i idnt kno what to do but bring it to someone that could fix it and he said the problem was the 50 volt regulator and charged me like 55$ to fix it i got it fixed and it worked for about 3 days and now the same exact thing is happening again. i dont kno if i want to bring it back to the same guy thinking maybe he just wants my money or its something im doing or just a brand new busted up *** amp.

Most techs offer a warranty. Contact him and ask him if he will look at it again and ask him if he's going to charge you to troubleshoot it. If its the same problem and it's not a problem caused by incorrect installation, shorted speakers, shorted speaker wires or an incorrect ohm load, he'll probably warranty it.

The main thing is to be polite. If you are rude or accuse him of ripping you off, you can be pretty sure that you'll have to pay to have it repaired again.

Let me know if you have any other questions.

How many 12v batteries are needed to run a 15000w inverter properly


It is normal to use only half of the capacity of a battery and this is called 50% depth of discharge (DOD) so the watts of a battery is volt X amp hours eg a 12 volt bat @ 200 AH would be 2400 watts but you can only use half of that other wise the battery will be stuffed, so all you have is 1200 watts, if you have a 400 AH battery you would have 2400 watts, you also have to know the capacity of the battery and this is call the C rating of the battery once you have that you can work out how many hours it will run for.
On an of grid system I would not use any less than 6oo to 700 AH @ C100
It is normal to size the batters to energy demand in KWHrs per day of (AC load )
Hope this help.

I have a new furnace and the breaker keeps tripping (20/30). It is a bryant westinghouse box. I think 200 amphes


1) You got a FIRE truck coming.

2) Wire is too small.
Problem is NOT circuit breaker.

3) Both 240Volt appliances on same breaker is a hazard, especially if space available in 200 amp service panel for more breakers.

4) Usually each 240V appliance has separate breaker.

5) Circuit breaker trips because of High heat on the wire.
If wire gets hot, it will start a fire inside the wall.

Electric code requires wire-size match breaker-size.

6) If you put larger amp breaker on same wire that is getting hot, then wire will get hotter.
Result: FIRE truck middle of night with folks jumping out window in glass-cut bare run across yard.

7) Each appliance has volts and watt rating on label.
EVERY appliance has label.

8) For example stove might be rated 8000 watts and 240Volt.
8000 watts divided by 240 volts = 33.3 amps
Stove would require 40 amp breaker and 8 gauge wire.

9) How to figure it out:
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-install-a-subpanel.html

10) Do same calculation for new furnace.
12000 watt furnace divided by 240 volts = 50 amps.
Use 60 amp breaker and 6 gauge wire.

11) Summary: fixya wants you to be safe, and buy stuff showing in the ads.
Use a bigger breaker ONLY when bigger wire is also installed.
Call furnace installer, the installer should know to check safe wiring before installing.

The voltage in US is 110-120 volts and the amperage is 60 amps. In your country the voltage is 250 volts which appears to be high as the general voltage in Asian countries 220 volts and the current is 50 amps You have to use a transformer/adopter which can reduce the voltage from 250 to 220 Or it is a universal adopter where this aspect is covered up. In that case you have to check the amperage. 300 watt is the power consumed and has nothing to do with low/high voltage.

I am not sure how you are measuring the power output to verify it is less than 200 watts. With a true RMS voltmeter you should see 28.28 volts RMS across a net speaker load of 4 ohms. If you use only one 8 ohm speaker, you will get 120 watts. If you are getting the 28 volts there is nothing wrong with the amp. You MAY have blown the speakers OR not generating much bass due to processing in an EQ. I assume you are using at least 15 inch speakers if you want to feel bass. Look up your speakers specs... you will need speakers capable of 32 Hz to feel much. With this amp your speakers should have aa total rating not less than 400 to 600 peak watts or around 300 watts RMS continuous power rating. Using a lot of high end EQ will keep the amp busy at the high end and reduce the power available at the bass end.

I have a trailer house that has a 100 amp breaker box in it. I has gas for heat, water heater and stove. I am changing them to electric. Will I need to change the panel put to a 200 amp.


Its probably not a bad idea. Thats alot for a 100A panel to handle, a range needs a 50A, a water heater needs 30A, and the heat will need a 50A or a 60A breaker... Plus whatever else is in the house will be a bit more than the 100A service can handle. But if you don't have the money it will do for a while because for the most part they won't all be pulling at the same time. Word to the wise get at least a 30 space panel when you upgrade, I always install a 40 space panel because for the cost difference its well worth it for future needs because you'll fill it up quicker than you think and you'll have space for anything else you may want to add later on. Hope I helped

Output and power transformers specs


What??? There is NO output transformer for the Mg50DFX. The outputs are direct driven from hybrid stick TDA type solid state amp chips.

The power transformet is probably about 100 watt size and supplies two voltages... one that feeds a +/- 15 volt three terminal regulators... Probably 22 volts +/- to the regualtors and the other supply will be unregulated to the power amp chips.

Is this inverter powerful enough?


You are right. This is not enough to operate this freezer. You are going to need a bigger invertor it get it to work properly 900 or 1000 watt should be efficient even though it is not the best way to run the unit. If the unit has a problem you would be replacing the inverter all the time. Just FYI

Inverter problem


If you got the store bought APC 350 UPS, you most likely overloaded them, and killed them beyound repair.

People should never buy a 350VA. They are way to small for power supplies most of us now have. you need to start out to 1000VA plus you need to do the math to figure out how big of a UPS you actually need in the show room.
What am I talking about? What is the significant, or the math of what I am saying here. 115V x 1 amps = 115VA x .778 power factor = 89.47 watts Start up 50 watts = 39.47 watts
115V x 2 amps = 230VA x .778 power factor = 178.94 watts Start up 50 watts = 128.94 watts
115V x 3 amps = 345VA x .778 power factor = 268.41 watts Start up 50 watts = 218.41 watts
115V x 4 amps = 460VA x .778 power factor = 357.88 watts Start up 50 watts = 307.88 watts

115V x 6 amps = 690VA x .778 power factor = 536.82 watts Start up 50 watts = 486.82 watts
115V x 7 amps = 805VA x .778 power factor = 626.29 watts Start up 50 watts = 576.29 watts
115V x 8 amps = 920VA x .778 power factor = 717.76 watts Start up 50 watts = 667.76 watts
115V x 9 amps = 1035VA x .778 power factor = 805.23 watts Start up 50 watts = 755.23 watts
115V x 10 amps = 1150VA x .778 power factor = 894.70 watts Start up 50 watts = 844.70 watts
115V x 11 amps = 1265VA x .778 power factor = 984.17 watts Start up 50 watts = 934.17 watts
115V x 12 amps = 1380VA x .778 power factor = 1073.63 watts Start up 50 watts = 1023.63 watts
115V x 13 amps = 1495VA x .778 power factor = 1163.11 watts Start up 50 watts = 1113.11 watts
115V x 14 amps = 1610VA x .778 power factor = 1252.58 watts Start up 50 watts = 1202.58 watts
115V x 15 amps = 1725VA x .778 power factor = 1342.05 watts Start up 50 watts = 1292.05 watts
115V x 16 amps = 1840VA x .778 power factor = 1431.52 watts Start up 50 watts = 1387.52 watts
115V x 17 amps = 1955VA x .778 power factor = 1520.99 watts Start up 50 watts = 1470.99 watts
115V x 18 amps = 2070VA x .778 power factor = 1610.46 watts Start up 50 watts = 1560.46 watts
115V x 19 amps = 2185VA x .778 power factor = 1699.93 watts Start up 50 watts = 1649.93 watts
