Looking for power supply for Durst L1200

[Vick Ko]

Looking for power supply for Durst L1200, either the TRA500 or EST500

Worse case, what else can I do? Power it off a car battery (24V, lots of amps)?

I'd also like to find the following:

- top AN glass for the FEMONEG
- long handled rod for the focusing knob

Thanks
Vick

Durst-Pro-USA.com (Jensen Optical) has all/most parts for the L1200. They are a little pricey but they are new. Saw one on eBay a few days ago; it might have been the German eBay...

Yeah, Durst-Pro-USA is expensive alright.
I'm leaving them as "last resort".

Thanks

Hmm, on this side of the border the cars all have 12V batteries

Here is one option for $50 USD if you are using a lamp 200W or less:

You can buy a Variac (= AC variable transformer) off the evil auction site that will supply 24v from household current. You'll need to rewire your color head with a standard 3-prong plug so that it will fit in the socket of the Variac. Make sure that the Variac can handle the amperage of the head (the more expensive it is, the more current it can handle).

I've done this with a Pavelle 401 (50v), and it works like a charm. I also use it to power 12v point-source halogen bulbs, and as a dimmer for standard opal bulbs.

BTW, please do read up on electronics and wiring before attempting this if you don't already have background knowledge in this area!

I'm trying to figure out the current draw of the head. I'm also sensing that the power supply output is AC, and not DC (as I had been thinking).

This would all have been so much easier if the previous owner had found the power supply.

Just look at the wattage of the bulb.

Watts = Volts x Amps

200 Watt bulb needs 200VA transformer or power supply

Yes the original power supply is AC, but it probably does not matter.

[polyglot]

For a bulb (with ZERO control electronics on it), it doesn't matter if you use AC or DC as long as it's the right (RMS) voltage.

Please don't use a variac. Apart from the risks of someone bumping the knob and frying the bulb or you, they have a habit of failing in such a way that delivers full line voltage to the load, especially when the load voltage is low. Connecting any non-huge variac to a 250W 24V load is pretty much guaranteeing there will be fire.

The best option is to go buy a transformer of the correct voltage and power rating and wire it up to the bulb. 24V toroidal transformers are readily available in 160VA and 300VA (for up to about 150W and 280W respectively) in electronics stores. Usual caveats about playing with mains voltage apply, not to mention you're dealing with moderate current that needs non-lightweight wiring and connections.

The OP has done himself a HUGE dis-service by starting multiple threads on the same subject.

I'm not about to waste my time posting the same answer on half a dozen different threads.
