Delta+XP 24VDC/5VDC 3rd Party Power Supply

Supplier: Integrated Power Designs: www.ipd.power.com Phone: 570-824-4666

Dual output power supply. Product no. CE-225-2101 with Cover - $273.60

Though size wise identical it is not just a plain swap. You have to tweak it a bit.

- To mount it on the metal plate (the original supply was on) you have to drill holes on the back plate by removing the board.
- The 220V input is two pin molex type with ground a separate spade type connector ( The original supply has a 3 pin molex type connector). But the two pins are spaced out so you need to buy a 3pin connector and not use the center one when connecting to the new supply. Clip the ground (Green and Yellow) and put a spade connector on it.
- The DC output is 18pin (original is 20pin) so you need to buy 18pin molex connector.

I got all these from mouserelectronics.com ( http://www.mouser.com/catalog/catalogUSD/641/1460.pdf)

The part numbers are: 538-09-50-3031 (three pin)
538-08-50-0189 (crimp pins)
538-09-50-3181 (18pin connector)

- The original specs of the Philips power supply are as follows: AC 110/230V, 6A/3A 47-63Hz DC 24V/8A DC5V/6A

- When using CE-225-2101 or any other compatible power supply, there is no need to re-connect the jumpers as on the original. Just the Brown and blue leads for 24V and 5V, that's all.
