new sunpak 383's

just got 2 new sunpak 383's and see they have a spot for AC power? anyone know what power cord goes on them or where to get one?

The AD-27 is the one but is showing as discontinued.

I am waiting for flashZebra to find some or start making a few.. I just know he needs a few more projects.. LOL

That port will accept a high voltage input. It is several hundred Volts (I forget the exact Voltage requirement).

You can use a high Voltage battery pack for very quick recycling of the flash. Or the mentioned AD-27.

The recycle times on the AD-27 are in the range of 20 seconds. I have a couple of AD-27 units and use them on occasion. But most would not be happy with the very slow recycling.

Enjoy! Lon

Hi Lon,

I don't know enough about electronics to understand this. Can you explain why using the AC adapter results in such long recycle times? What is different about the current supplied with the adapter as opposed to using batteries?

Robert,

An AC adapter would not have to result in slow recycle times. It is just the case that the AD-27 does.

The AC adapter for the Vivitar 283/285 is also anemic (but faster than the AD-27).

To get fast recycle times the AC adapter would require a much larger transformer for the power supply that would both be more expensive and obviously much larger.

For whatever reason Sunpak decided to take the design approach of a small transformer and keep the AD-27 small and inexpensive (and anemic).

I am out of town right now or I would just look at the current supplied by the AD-27 (it is most likely on the adapter). But, it obviously is very modest compared to what the high Voltage battery pack can supply.

Enjoy! Lon

DON'T DO IT. That's not for AC power, that's for a high voltage DC pack. Put 110/230V AC in and they'll explode, or do something spectacular. If you do plug in AC take some video...

I just bought a TR PAK II (or something like that ) from a guy on DWF, you can find them on ebay sometimes. I also just hooked up a 6V 7AH sealed lead acid battery to a 383, it cuts the recharge time from 12s to 2sec. It took a bit of soldering work but I think it was worthwhile.

I can attest that the AC adapter on the old Vivitar 283 back in the day was almost as anemic. I never understood why, but it was by far the slowest of all the recharging options available. If I could find it again I would be more than happy to give it to anyone that could use it, but it was such a worthless piece, I'm sure it is lost forever under piles of other junk.

thanks all.
i was just perusing some older threads and saw mention of a battery pack for the 383s. I'm going to look into that a bit more.

Lon,
the cords for the 383's and sky ports work great. Thanks again!

^^ I agree. they do make things work really well don't they?

Or you can make a 6V sealed lead acid battery pack, which charges my 283s from full power discharge in <2 sec

Yeah mine works really well too.

Mind giving me a link to a tutorial or such?

It's pretty easy to do, just connect the SLA battery to the camera. You can use "fake batteries", or you can do what I did, take the batteries out and solder wires directly to the PCB inside the flash. Fake batteries are probably a better bet.

Have a read of www.aljacobs.com

I second the 'fake batteries'. Cracking it open is far too much work
