Saunders / LPL 4500 II Super Dichroic - Power Supply Options

[Todd Barlow]

Hello all:
I saved the above enlarger from the land fill.
Unfortunately there is no power supply and it may be an older model with the square cable end that plugs into the power supply.
I prefer not to invest $600 in a new or refurbished LPL power supply, so I was wondering what options I could consider.
It has a 4 pin cable (power, ground, neutral, ?) and the bulb operates at 82 volt.

Any thoughts would be appreciated.

Thanks

Todd

ebay? I got 3 Omega D5500 power supplies and a Philips 150 supply from ebay over the years. The For Sale forums here at APUG I got a Omega D power supply and Minolta Mod III power supply and over at LF For Sale forum I found a Durst power supply.
Even with all that I still look because only 1/2 of my enlargers have a 'working' spare. The other 1/2 have busted spares that I keep for repair some day or no spare at all.

The power supply operates the lamp and also the ventilation fan which I am pretty certain are different voltages.
If you don't mind butchering the cable to the head the original (and probably unobtainable) 4 pin connector could be cut off and the wires reconnected to whatever power supply device you end up with.
Lamp volts are as you say 82V and this could perhaps be obtained by cannibalizing the power supply from a parts donor overhead projector that uses the same lamp.
The fan volts I don't know, but might be able to find out in a little while if you can wait.

Have you asked KHB?

Hi all thanks for the feedback.
I will be shipping the unit off to another APUG member who uses the LPL4500 for spare parts etc.
All the best
Todd

Good on you Todd, for rescuing a fine machine.

If it's helpful to anyone else facing a similar dilemma, when the original power supply on mine died, I rigged up a household dimmer. To set it, I temporarily connected it to 200 Watts worth of load and adjusted the slider until my meter showed 82 volts. Then it was a matter of identifying the pins in the connector and making the connections. The fan runs on 120v, the low voltage is only for the lamp.
I ran mine that way for a couple of years until I found an affordable original power supply.
