I came across a DZ075 power supply. It says it is +24.0V/3.0A. Can that be used with a breadboard? Or do I have to get it to 3.3V or 5V before I plug into the breadboard. In other words, can it be plugged into the board then make it 5volts or before?

I took the cover off and found there are 8 pins. The last three are +24V, the middle three say ground, GND, and the first two are not connected, but the pins available and say +5v.

I do not wish to be electrocuted or destroy stuff.

Edit: Here is a picture:

Edit: Could I move the connector all the way over to the left? It would be connecting two 5V, three GND, and one 24V (the connector is only six connections).

Edit: I'm not sure I should use it. The amps are high. From this calculator, http://circuitcalculator.com/wordpress/2007/09/20/wire-parameter-calculator/ it looks like my 23AWG wire is too small.

  • \$\begingroup\$ @AliChen I am hoping it is. What about the 3A part? \$\endgroup\$

  • \$\begingroup\$ what about "3A"? According to summary datasheet, psui.com/wp-content/uploads/products/Tri-Mag/DataSheets/… you have DZ075-9 model. The table says 24V3A and 5V0.5A. Breadboarding generally requires more attention to details. \$\endgroup\$

The breadboard itself (assuming the usual plastic boards full of holes) doesn't care what voltages you use on it - however, the circuit you are building DOES care. If you are working with common digital ICs, then you need a 5 volt (or possibly 3.3 volt) power supply.

If you are working with other types of circuits - an audio power amplifier, for example, you may need 24 volts, or +/- 15 volts, or something else.

If your circuit wants 5 volts, you could build a votlage regulator on the breadboard to reduce the 24 volts from your supply to the 5 volts your circuit requires, but it may be easier (and safer) to buy a 5 volt "wall wart" supply.

  • \$\begingroup\$ Yes - the MB-102 is what I assumed you meant by "breadboard". \$\endgroup\$

Look through the internet, you will find pinout. Here's what I found here

Output:

Pin1,2 = +3.3V === 6A

Pin3,4 = COM

Pin5,6 = +5V === 4A

Pin7 = -12V === 0.6A

Pin8 = +12V === 2A

Edit: thanks for posting the picture. It is not that one I found :P

I guess if something wrong will happen to breadboard, manufacturer will be refusing from warranty obligations because you did not use recommended power supply (if such was recommended by them). Thus think twice before re-using it.
