Heavy Duty Light Sequencer.

[RayH]

Hi
Can anyone help with a circuit for the above, must have a minimum of 4 channels and be able to carry at least 150amp per channel. will be driving 40/60w lamps of 110 or220v.
Any advice appreicated.

40/60W lamps using 150A?

 

[RayH]

yes there are over 1000 lamps to be controlled

 

[panic mode]

what is the clock rate and how would you like to run it? chasing lights or something else?

I would suggest you use multiples of three channels!.

As the supply requirements are well above that of a domestic supply you will need a commercial three phase supply - so it makes sense to split the channels equally over the three phases.

I would also suggest you use many more than three channels, that way the control systems per channel come back down to reasonable sizes.

A lot also depends on how far these lights need to be spread over - if it's over a long distance it makes sense to have a number of seperate control systems, perhaps linked together via serial connections, radio links, fibre optic links etc.

You really need to give far more details of what you are trying to do, not to mention considering the costs involved - which will be considerable!.

Hi RayH,

In this place,**broken link removed**, you can find a base project for your needs.

As Nigel suggests, use sub channels to cover a 150A load
per channel. Anyway, this light project needs some modifications to allow drive at least 4 40A triacs at a time or phase controlled solid state relays.
