We have an Electroluminecent Lighting product and have been asked to provide a 6 channel sequencer, the problem is the output to drive the Lamp is 260V/500Hz/0.054Ma from out standard 220v inverter. We can only find low voltage products, any ideas on who can produce a product for us.

So you have 220V 50Hz to start with?

You need 260V/500Hz at 54uA? Or 54mA? (You have stated 54,000 amps!)

By "sequencer" what do you specifically mean?

The output from the inverter drives the lamp at 0.00054 amps per square inch, we want to drive 50 square inches in total 0.027 amps.

We need to drive 6 lengths of Lamp 25mm (1") wide by 1.3m (51") long, the inverter/driver is an SD50 unit that drives 50 square inches, only one of the six lengths to be driven at once, we need a unit to sequence of chase between the 6 lamps in a random/programmable order.

Are you looking for someone to design and manufacture a custom box for mass production? Or a quantity of one? If you're just looking to put together one for a particular installation or a demo, maybe you can use a stage lighting controller like the ones from Chauvet.

Seems to me that the DIY project still fits the bill, except that you'd replace the lighting ballast switch on the SD50 with one that's controlled by the PIC.

This is for a specific application and would be a compact, simple, custom box for mass production, i have looked at the Chauvet this would probable do the job if it had 6 channels have ordered one to give it a try.

The Eye Candy sequencer deisgn would work but we need it professionally manufactured and would prefer to get it done in the UK rather than sub out to the Far East.

So you have the driver - The SD50 that can provide the power? There will only ever be one "lamp on at a time"?

I would point out that often 'chasing lights' seem to be all of them ON with one of them OFF and the chasing actually being the 'dark'. Of course this would require five SD50s or one of your larger drivers and a little more complexity.

Doesn't sound particularly hard. The user interface would probably be the the most effort, (unless it's extremely basic). Followed by packaging.

You might want it extensible as the next person in the door may want 7 chasing.

If these aren't seriously cost sensitive you might want to consider some other features as a micro could do many more scenarios than just chase and random with only some additional software.
