Echostar 450 watt switching ps

Bought this unit surplus; wanted to use it to power a 3.6 volt dustbuster, but  I get no output from the red and black wires. Am I missing some power up switch in one of the connector leads? Thanks in advance.

     One more question Jemthy. Any idea why, when I put all the orange(3.3 V) wires together(there are 3), and all the blacks together, it shuts down when I try to use the dustbuster? It says the 3.3V is good for 34 A , but the dustbuster draws only about 10.  Thanks in advance.

    Thanks for your reply Jemthy, but I already tried the 5 V lines, and it did the same thing. I hooked the dustbuster up to a power supply and it works fine, so the problem is not the dustbuster.

You need to short the ATX power supply to ON. Follow this steps. look for the GREEN and GRAY color wire in the power connection that usually connected to the motherboard of computer. Get a short wire and insert to the hole of GREEN and GRAY to short the switch. Good luck don't forget to rate my solution if helpful to you.

    Try to use the 5v the red one, because there is equipment that using 3.6v then you supplied by 3.3V or lower the voltage that required the machine is not running because the 3.3v is not enough to supply the source in the machine power supply. Because some voltage is drop already maybe 3.3V is 3v only when the power got inside the power supply of the machine. I think 5V is enough and safe to run your dushbuster above 5V is not recommended.

Wheel Horse 111-B&S 11hp eng-where do i conect red & black wires from charging system

Your Briggs & Stratton uses a dual circuit type alternator. One side of the unit produces up to 3 amps of DC electricity via a one way diode so that only the positive charged electrons pass through converting the AC from the alternator into DC after passing through the diode. This wire will have a slight lump just before the wire terminates at the plug. This is the wire that will be red and it needs to be connected either to the battery side of the solenoid or directly to the positive terminal of the battery. This keeps the battery charged an also provides enough power at full speed to run the electric clutch.
The other wire does not pass through a diode and therefore produces AC current for the lighting system only. This will be the black wire after the connector. The black wire connects directly to the headlight switch. The AC side produces 5 amps at full speed and therefore enough to power 60 watts of lighting at 12 volts. The typical 1156 bulb uses 28 watts x 2 = 56 watts and if the unit has taillights they are normally 3 watt bulbs. The headlights will be dim at low speed and reach full brightness at full speed.
In Summary, red wire to battery and black wire to light switch.

Hope this helps.

With the vector 2000 watt converter do you need to run 2 batterys.

well unless you bought the 24 volt unit no one battery will run the unit, according to black and decker this unit is not being made, did you buy it new or at a yard sale?
one way to tell is look on bottom of unit, it will tell you if it is 24 or 12 volt model.

I have a smps(model compaq PS-5500-1C). How can check its out put volatage?

Hello Anvar, hi, to run the power supply on its own, you need to short the green wire with the black wire. (plug in the unit)
using a Volt meter, select a range of DC 50V. put the black probe of the voltmeter to any black wire, and the red probe to the ff:

red is 5V
Yellow is 12V
orange is around 3.3V
Blue is negative 12 (switch or interchange the probe to properly read 12V on the voltmeter)
White is negative 5.

What are the outputs of the varios plugs & sockets of a Delta Electronics power supply model SMP-420BB when supplied with 230 volts AC input

Forget about the individual plugs. Concentrate on the wires.

The Delta SMP - 420BB is just another
Switched Mode Power Supply.

(SMPS shortened to SMP by Delta. I'm speculating here, but I'll bet the 420 stands for 420 Watts)

No matter what the input voltage is, the SMPS will only put out three main voltages.

1) Wires with Yellow insulation are 12 Volts
2) Red wires are 5 Volts
3) Orange wires are 3.3 Volts

ANY Black wire is a Ground wire.

For example:
1) 4-pin white Molex power cable.
1 - Yellow wire
1 - Red wire
2 - Black wires

(4-pin Molex power cable is also referred to as a Peripheral power cable)

No, the 450 is just one of those machines that seem to have PCQ no matter what you do. Given light copies, I'd replace the drum for sure and make sure your ID sensor isn't covered with toner. Dust covered optics will also cause light copies on this model.
