    Colleagues, good afternoon! I want to use the PSU servers for recreational purposes. I have a power supply Delta Electronics DPS-510BB, output voltage of 5 Volts, 19Amps and 12 Volts, 35 Amps. Electrical circuit no. Help with the inclusion of this block, the output connector has 6 large and 16 small contacts. Probably, this unit has a lock and in order to enable it, you need some contacts to close. Can anyone help me in solving this problem?

    Put your part number & RC (for radio controlled, as they use server supplies to charge battery packs). You should find info on yours, or glean enough to get it up & running.

    Ed, thank You! Here is Part Numbers - (P) PN - 42C2141, FRU PN - 42C2140. I don't know who to ask, as I don't know what server was this unit. Searchin Google gave no results.

    Good morning for all! (In Moscow is morning). Thanks for help and information. The first photo is my PSU - 6 large and 16 small pins.The second photo doesn't fit my power -there are 11 large and 24 small contact and the output is 3.3 V.In my power supply only outputs 12 V and 5 V. I saw link by Ed - find DPS-600, but a description without a picture it is not clear how the numbering of the contacts, the more it is about 12 small contacts, and I have 16 small contacts.

    Have you popped the top ?

    If it is like many of those supplies , Look for the green wire going to EN (Enable) on the board.

    When that pin goes low by grounding, the supply output is enabled.

    Near as I can tell that supply was used by IBM.

    Good Luck.

    Michael -

    The Radio Control (RC) Hobby has numerous modifications of these Server SMPS.
    Drone business has attracted the electronics "experimenters" and "DIY Builders", that are disappearing from amateur radio.

    Hello RA3DQP,
    I have the same supply, which appears the same as a supply for a Sun StorageTek 2540 array 300-2051-01. The 42C2140 says it is for the IBM DS3400 disk array.

    I did some checking on it and attach the following image. The 12V lines are the left two power blades, grounds are the next two. To the right of the control pins is another ground and the 5V line. On the control lines, the power_on signal that needs to be grounded is the top row, third pin. There is a ground at top row, second pin, so I added a simple jumper. By default it provided 12.04V. If you are technically trained you can open the supply and tweak a variable resistor to raise the voltage to 12.3V, but you should not open the case if you are not trained as there are high voltages present, even on one of the heatsinks. The fan speed appears to be partially controlled by a thermistor near the front of the supply. I haven't checked the supply noise or figured out the other pins. The blue pin when grounded turns on the blue 'safe to remove' LED.

    To AB9TO:
    Dean, thank You for Your help. I dont have free time for me experience. May be later testing. I need only 12V power, do You know why make from 12 V 13,8 V. May be change some elements&
