Powering a 347 Volt SOX ballast (2)

Powering a 347 Volt SOX ballast (2)

Click to view full size image

Using 120v 60Hz on a 350 watt PSMH multi-tap ballast, with everything else capped, including the ignitor tap and lamp out but leaving the capacitor as wired, I simply connected the 347 volt tap of the PSMH (& 2nd COM) to the 347 volt LPS ballast still mounted on the Alpha 4. 135w lamp lights up normally to full power.

Nice! Are you going to put it into service like this?

I'm going to sell the Alpha 4s without the L73/L74 ballast. I could also trade a few here on LG.

Will also sell the 347v ballast by itself with these directions (how to power it with 120volts).

I've done this with ballasts, you don't even need the cap

How do I wire a ballast to power a 240 volt ballast?

How do I wire a ballast to power a 240 volt ballast?

Use a multitap ballast and wire the 120v to your 120v input, the 240v of the multitap ballast to the ballast you want to power, and don't forget to cap up the lamp lead of the ballast being used as a step-up transformer.

Use a multi-tap ballast with one tap being 240 volts, and with higher watts than your 240v ballast.

Just wire the HPS, M-H or MV multi-tap ballast with 120v and use the 240 volt tap to power your 240v ballast.

You might also be able to use the 277volt tap but the output might be too high. In this case I'd use a multi-tap ballast equal to or slightly less watts than what you want to power.

Oh yeah I forgot about the higher wattage thing.

So I can use my multi tap 1000 watt halide to power my 400 watt 240 volt ballast but how do I get 2 hots for the 240 volt?

You mean +120v & -120V? What sort of 240V ballast are we talking about here?

All multi-tap ballasts typically have 2 COM wires (wired just under the covers)... From your wall use 120v & COM. To your ballast you need to power up, use the 240v tap & the other COM. You can wire all COMs together if you only have one.

I was under the impression that a 240 volt only ballast I would use the 240 volt input and the com. As the other hot! And then have only an earth ground.. like a 240 volt water heater

No (I think). You have 2 ballasts. You exploit your 1KW ballast with 6 connections (ground included)!

Connect from your wall outlet to the 120v & com of your 1KW ballast.
Connect your 400w ballast to the 240v tap & com of your 1KW ballast.
2 more connections for earthing onto the core of the 1kw ballast. Done.

That's explains why you have to convert the proper voltage for this LPS ballast

Pretty, please no more Chinese failure.

This trick is often used on factory wired HID fixtures designed for higher voltages to power the 120v halogen restrike lamp too. In fact some ballasts will mention this on the label.
