Omron Power Supply

[faiunie]

Hi I got OMRON S82F-3024 (24DCV 14A) Power supply I salvaged from my scrap. I test it got no dc Volt.I supposed it spoilt.U guys got any idea where I can send it for service.Or u guys got any idea how to use these PS.

Hi faiunie

If wrong connection to the power supply, it will not turn on. Make sure your wiring is correct.

To connect... Leave the Voltage Select to open.
Connect L to Live and N to Neutral and FG for ground. Don't turn on main power yet.


Then connect +S to +V and -S to -V.

The +R.C and -R.C. I think is a Remote Control or Remote voltage control or Remote power on. This one u have to refer to the manual.

Then turn on the main. Measure got any D.C. O/p at +ve and -ve.

Hi bro I did it but there is still no Voltage at DC.So does you know where Ican send it to repair.I intend to use it on my 11V-15V DC charger.

Have you try to connect a load at your DC output. Some of the old swtich mode power supply require a minimum load to make it run.

Yup I did 10w 10ohm Resistor load up + and - DC. Still no o/p volt.

Hi faiunie

I do not know where to send for repair.

U want to do one last try? Now measure the +RC and -RC with voltmeter. See whether does it got any voltage or not. If not, connect voltmeter to the o/p and try shorting both +RC and -RC point together to see how.

At last open up the casing found to be one of the two Capacitor faulty.Both of the same capacity 200V 1200uf.When to Sim Lim Tower go to most of the shop they dont have the same rating.But they got 200V 1000uf or 200V 2200uf.So can I buy one of those and mixed with the original 200V 1200uf.Or I have to change both Capacitor of the same rate.Will it effect my dc o/p of 24Vdc 14A.And how can I change my o/p to get 12Vdc what mod can be done?
NEED your expertise GUYS
THANKS

200V, 2200uF should be fine.

To mod to 12V output, better get hold of the original schematic first. I guess you will need to change the transformer turn ratio and the load sensing path which is usually a voltage divider design.

Thanks Bro for the reply.So do I have to replace both Cap of same rate or just replace the worn out one.

Don't think the 200V, 2200uF is expensive. Why not buy 2, try to replace the one that is bad and keep the other for spare.

Hi Bro so u mean I can mixed up the Cap rating on the circuit board.

[Super-Hornet]

Eh... Try not to mix your capacitor.. Get same or higher Farad for your capacitor. As for Capacitor voltage, get equal or higher.

If I'm not wrong, the schematics using 2 capacitor is because it is design for 120V and 240V. For 120V, it uses 1 capacitor. For 240, it uses 2 capacitor in series in order to charge up D.C. voltage... after rectified the A.C. 240V.

Hi guys u got any idea how to step down these 24vdc to 12vdc.What mod should be done.

Something I have overlooked, the voltage rating of 200V might be at a lower side for a 230VAC input. To be on a safe side may need to get something higher.

Hi guys went to SL tower bought 2x 200V 1800uf .Solder it back cant get it to power up.....Sigh.I think I give up oredi.
