SOURCE: Have a 24 volt dc motor. (34 amps) Supply is 24

Hi, you should not have to, the motor spec is max current draw, maybe when stalled, the supply is a theoretical maximum so you will be fine, in case of faults a breaker or fuse rated at 35 amps would be good.

My VEON 55inch Model SR09112 cannot on, when we keep trying to on ,sometimes it is on , after we switch off we have repeat again . but sometimes it cant on at all


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Reduce 67 volts to 48 volts dc


Just google for voltage regulator 48 V and you have lots of solutions. Be aware of the current going through a regulator. To reduce almost 20 volts each ampere will generate 20 Watts of heat, unless you use a switching regulator.

What or how does the battery get its charge


Most bike have an alternator driven off the left-hand crankshaft shaft.
This turns with the engine, producing the AC charging power.
This power then runs through a voltage regulator, that both converts the the AC voltage into DC voltage, and regulates the amount of voltage flowing into the remaining electrical system.

Now, you did do the first step correctly.
DC volt meter to battery terminals to see if you get 13-14 volts DC with engine running.
Next, locate voltage regulator and unplug connector for wires coming FROM the regulator, and hook up the DC voltmeter.
With engine running, you should have 13-14 (or so) DC volts.

If not, locate and unplug wires coming from alternator to regulator, and hook up AC (note change from DC to AC) voltmeter.
With engine running, should have AC voltage (this could be 20-40 volts or more).

This will let you know where the problem is, and what needs to be replaced.

Test dyna regulator


NEVER EVER pull the positive cable... thats an old trick for cars and old style charging systems... but then again it's your harley not mine. you need a DVOM set to AC volts to test the stator and set to DC volts to test the regulator... anwhere from 5-20 ac volts coming out of stator and 12 volts dc going TO regulator... yes then regulator, no AC volts out of stator... pull the side cover as mentioned above...

How can i know if my voltage regulator is working, Im not getting any of my lights to work


quick check is to remove a battery cable while the motor's running. If the motor stays running when you pull off the battery cable, the charging system is functioning properly, if it dies then there is a problem with the charging system. Don't leave it off long, as this test is stressful to the circuit. You can test the voltage regulator by putting a volt meter across the battery posts to verify voltage. A fully charged 12 Volt battery should show slightly above 12 volts DC. With the engine running and the volt meter hooked to the battery, the charging system should be showing around 13.8 volts DC.

How can I operate my LG 26LE5300 LED LCD TV in my motorhome the most direct way possible (i.e....without an inverter)? This low power (40-50 watts) TV has an external brick to convert 120 AC to it's...


1) You need to look at the output current rating (AMP) of this AC to 24dc adapter, this 24vdc adapter is a regulated switching power supply that will maintain 24vdc output up the maximum current rating and also has shutdown circuits if the over current draw is detect and also if the output voltage goes up beyond 24vdc to protect the load (TV).

2) To use 12vdc to 24vdc DC-DC booster, it should have the following spec:

A) The output current rating should be at least 20% higher than the load requires to give its head room.
B) It must have regulated output that will maintain the 24vdc when the input (12vdc) will vary from 10vdc ~16vdc or higher since your batteries will not maintain exact 12vdc all the time.
C) It must have good protection circuits that will protect it self from reverse polarity connections, shorted output protection, over voltage output protection.
D) It should provide AC ripple spec on the 24vdc output, it should be in the milli-volt range (you will always get AC ripple riding on top of DC when you rectify the AC into DC).

These are the minimum requirement for your DC to DC booster, which you need to protect your TV and your motor home from burning down.
I hope I explain it OK to you.

Sir, while ago i sent a message to you regarding my 1202-vlz3 mixer (mackie) i to know how much the secondary voltage supply ?? thanks and god bless


The schematics don't show this, however reverse engineering this there are two windings... one is for the phantom power of 48 VDC... this winding needs to provide about 55 to 60 volts DC to the 48 volt regulator. EXPECT around 40 to 50 volts AC on this winding to the full wave bridge of D1,2,3,8.

The +/- 16 volt power regulated by LM317 and LM337 regulators will likely require about 20 volts DC into the regulators. It will be less than 25 volts because there is a 25 volt cap filtering.

Given a 20 volt DC from the diodes D5,6 and diodes D4,7 the transformer will be around 15 VAC either side of the centertap.

A minimum would be 12.5 VAC and say 18 VAC either side of center.

You should see near pure DC across C1 and C2 with only a little ripple of 2 volts MAX. The ripple should be 120 Hz. An oscilloscope is your friend in this area !!!

TV Needs new 5 volt regulator


Check for DC output at D653, if you have voltage there find Q682 and measure the voltage at the emitter. You should get 5 volts.
Just a question, if you are missing the 5 volts; do you have any other functions on the TV not working?
