question on LAMOT for Durst 184

[croski]

Hello I have a question. my durst has LAMOT 220v /50hz.

but where I am moving in 110v/60hz...

is it possible to change inside LAMOT ? or is it possible to buy new one ? or is it possbile to make it manual ? ( like moving by handle or something)

anyone know anything about it ?


Thank you !

Your best bet is going to be a 120 to 240 transformer. I know the Hemot came in 120v but not sure on the Lamot. Some of the controllers have dual voltage capabilities by way of jumpers inside the box. Open it and check. You may also find a handle for it used or at auction.

What specific enlarger head is involved, and its wattage? And what country are you moving to?

All USA homes have 220/240V available. You just have to know where to look.

Can you run your Lamot at 60Hz? I'd think it would be OK (see lower graph). Summary: motor won't be as strong but will run cooler and may last longer.

Image shows 220/240V outlet I installed for my Durst, I'm OK because the L1840 can run on 50 or 60 and still the timer and motor speeds work the same as neither is calibrated from the input Hz:
174531
174532

So do you have a Durst L-184 or a DeVere 5108? You have questions on both? What's up?

I have the LAMOT 110v. Both 110V 60Hz (fuse 2A) and 220V 50Hz (fuse 1A) are 70W. I don't know if a step-down Voltage Transformer will work, the LAMOT is a very simple motor that turn the end gear and 70W is not a big deal.
But I know that you cannot operate the LAMOT motor manually, you have to remove the motor and replace it by a manual crank, this crank can be found sometimes on eBay but I never saw a LAMOT on eBay. Bringing the 240V in the darkroom is another option as ic-racer said. I don't think 60Hz instead of 50Hz will be a problem for this motor. Frequency will not change either with a Voltage transformer.

I agree with Luis, see amazon/ebay for a travel transformer 110V/120V to 220V/240V Step-Voltage Converter, it may do the trick for $10 to $20.

A modern step up travel converter may have safety solved, see specs.

If you use a traditional transformer then, for safety, you may need to install a RCD safety breaker (https://en.wikipedia.org/wiki/Residual-current_device) in the transformer's output, because the secondary coil is isolated from the primary coil and, because that the RCD at you home may not break down in case you are electrocuted, ask an electicist before risking.


Finally if you need to obtain 50Hz you have another choice to generate 220V/50Hz. Use a savaged or new UPS (uninterrupted power supply) from a PC, remove the battery and feed the terminals that were connected to te battery with a 12V power supply. In that case you will be using the power electronics of the UPS to ondulate a 220V/50Hz power supply. Also you can use a 12V DC to 220V converter for cars, this is some $40 for 1000w
