Question about Motorola (6200510300010) Power Supply

Motorola DC power Supply (0-40volts, 0-40 amps cc) M/N R101AA, S/N 261CCl0469

I have an old Motorola DC power Supply. At first it would not power up so I changed the power Transistors (4each) on the back of the unit. Now it powers up and gives me 62 volts DC output with no control of voltage or current control. Can any one point me in the right direction? Maybe even a location of schematics. Thank you for any help: Rick the Machinist

There is a book, "Electronics for Inventors" (check Amazon), that will give you the basics of power supply design and electrical components including general scematics. Without more info on what the PS is supposed to produce in the way of voltage and current, there's not much more to be said.

How do I charge a string of say 10 x 18650 Lithium batteries?

Can get a 4 gang charger on eBay, ~ $20.
If they're wired in series, (nominal 37 volts) will need a DC power supply capable of 40-50 volts DC. Limit the charge current to 1-2 amps with a series resistor or a small 115 volt light bulb..

I misplaced the power supply and need to find another but don

look at the specifications of the old power supply in the manual or on a sticker on the back of the unit. It should give a DC voltage and an amp value. Get any power supply that has the same DC voltage and same or slightly higher amp rating.

What adapter do i need to connect a uniden bearcat pc78 elite inside my home

Hi Ray,

This is a mobile CB radio. According to the manual, it requires 13.8VDC @ 2.2Amps. You will need to provide an AC (house or alternating current) to DC (direct current) power supply capable of providing 13.8V at 2.2 Amps. This means the supply would be working at 100%, so obtaining a supply that would provide 4, 5 or more amps would be much less stressful on it and significantly reduces the chances of a 60 cycle hum present in the receive and transmit audio.

A representation of 13.8VDC @ 4A power supplies can be found here for $40 and up. Of course, you can go to a local electronics store and find them too. Check eBay for these, too - here.

You should be looking for a power supply that will provide 12 - 13.8 volts DC, and provide 3, 4 or more amps. The amp capacity is what will change the price - the more amps the higher the cost. You may see small "switching" power supplies - they are smaller, lighter & cheaper than traditional linear or transformer based types - so if that is the type you want to get you might want to get one that is a little bigger (5 or 6 amps) than the transformer type to get the same performance.

I hope this helps & good luck!

My Samsung ln40a530p screen looks good and normal for a few minutes right when I turn it on. Then it gets real dark and not as clear and I can see images burned in the corner from a channel that was on...

That symptoms have problem in back lights supply.The back lights have drive board that energies the back lights, the drive board have 24v dc from the power supply.So if the 24V dc output of the power supply have faulty because of leak capacitor,the back light drive board is did not oscilate to energies the back light.So the problem is either in power supply the 24v dc output,the drive board or the connector of the back lights in the drive board is loosen.

I have a Motorola 2210-02-1002 modem for a D-Link WBR-1310. I need a power supply for the modem. Can you tell me what the power rating is for the 2210 so I can select the right power supply? Thank you very...

You will need a power adapter with 12 Volts DC with .42 amps. The barrel will have to be negative and the tip is positive. It has these specs written on the back of the modem, just above the power port.

Htr 5630 shut off in 2 sec.

Sounds like you have a bad amp IC or transistors.
When these go bad they almost always put roughly 40 volts dc from the amp power supply to the speaker terminals. The protection circuit senses this dangerous (to your speakers) dc voltage and disconnects the speaker terminals from the amp via internal relays (the ones you hear click) and puts it into protect mode. If it didn't the dc voltage would quickly toast the voice coils of the connected speaker.

Image source 50 code E64

E064 Error code details Power supply voltage error (high-voltage error)

0000 The presence of a high-voltage error is communicated by the composite power supply PCB.
(The output for primary charging, developing, or transfer has deviated from a specific level of voltage.)

Main cause
 The contact has poor connection. The wiring is faulty. The composite power supply PCB is faulty. The DC controller PCB is faulty.

1. Contact
 Is any of the contacts of the primary charging roller, developing assembly, or transfer charging roller soiled? Or, is there poor contact?
 YES: Clean the contact, and set it once again.
2. Wiring
 Is the wiring between the contacts for the following normal: DC controller PCB (J301), composite power supply PCB (J136), primary charging roller, developing assembly, transfer charging roller?
 a. DC controller PCB (J301) <-> composite power supply PCB (J136)
 b. composite power supply PCB (J130-7) <-> primary charging roller contact
 c. composite power supply PCB (J130-1) <-> developing assembly contact
 d. composite power supply PCB (FT133) <-> transfer roller contact
 NO: Correct the connection.
3. Composite power supply PCB, DC controller PCB
 Try replacing the composite power supply PCB. Is the problem corrected?
 YES: Yes.
 NO: Replace the DC controller PCB. pls rate for my good deed!!!!!!!!Good Luck

Got flat screen as a gift

This monitor requires a power supply with a POSITIVE tip polarity.
Monitor requires 12 Volt DC @ 3.3 Amps output.
Make sure voltage is 12 Volts DC [absolute requirement]

Power Supply can have greater than 3.3 Amp capacity. More amp capacity increases price, so I wouldn't go for more than 5 Amps [minimum 3300 milliAmps, 5000 milliAmps will be more than adequate].

Put a surge protector on your computer and monitor to extend their life....better yet, a power conditioning battery backup system, that can supply constant voltage, to compensate line voltage when A/C, furnace, or other major appliance kicks on.
