ATI and the WorkPrinter

[reg8mm]

This combo may indeed work.

Premiere has captured single frames in manual mode as fast as I could press the button during a tape input capture.

I am using a ATI AIW 128 Pro 32mb analog video card with s-video, a Mad Dog Performer 2 sound card, Win 98 SE, an Athalon KT7A-RAID mother board, a raid 0 using two 30 GB 7200 rpm hard drives set up in the Raid IDE slots - one in each, Premiere 5.1, and the Video WorkPrinter 2, with a variable speed controll adjusting knob on this unit.

Film test to follow.

Oh yes, the camera:

Hi-8 exr, Sony TRV-65 NTSC, 20x optical.

Have you got this system up and running?
How is it working?

If you ever have the time, I would love to know if Dodcap works with this combo also. I have tested the ATI 8500DV card with Dodcap and it works fine, but I have never tested your particular card. If you want to test it, you can get it at http://www.alternaware.com.

It was working in the States and ran at top speed without any smearing.
Now that I am in the UK I am having problems getting a proper power converter to work with it. The small Radio Shack one didn't do well as it went all stinky and the projector stopped when the bulb was on with the motor.
The computer works fine.
The ATI card does not accept British television but has many other countries and not France either.
Resources in Thornbury are exhausted and Bristol is next, at least the Causway shopping center for a TV use power converter for over 50 watts. My TV was 52 watts. I fried it this morning with a power converter that was rated for 50 to 1600 watts?! That wasn't right. It went, BANG, and white smoke fell out of it.
My 16mm projector doesn't work either, not with the bulb on anyway. It is a Bell & Howell with a DC and AC switch.
\more later.

Hi, Michael!

This is VERY important: My experience is that the power over much of Europe and Asia widely varies from as low as 220 volts AC to as high as 256 volts AC. Even if you call the local power authority, they will say "220 on average" but the only way to really KNOW what you have is to put a meter on the wall outlet. Even here in the states, the power can legally go as high as 128VAC.

The problem is that typical power convertors merely cut the voltage in half or by an appropriate percentage, depending on the windings in the transformer. For instance, a normal item like the WorkPrinter won't care about the 50 cycles as long as it gets nominally only 110 volts, 115 tops. IF the incoming voltage to your flat is REALLY only 220, then you have no problem. However, if your incoming voltage is as high as 256 volts, then you would be feeding the WorkPrinter (or any other device) as much as 128 volts! Yikes!

While most American appliances could weather 128 volts at 60 cycles, their thinner wiring will generally fry if 128 volts is applied at 50 cycles, as the lower the cycle rate, the thicker the internal wiring must be. That is why military jets have generators that operate at insane cycle rates, like 10,000 cycles or something like that. They can then use really thin, light weight wiring. Conversely, lower cycle rates like 50 cycles needs heavier wiring than items operating on 60 cycles.

So, before you buy convertors get a meter and check the actual voltage coming out of the wall and then buy an appropriate convertor that achieves the correct reduction to keep you in the 110 volt range. Even then, put the meter on the output of what ever transformer you buy and make sure that it is putting out the proper power. Don't trust the label.

The WorkPrinter needs a transformer that can handle about 2 amps so the really small transformers won't do the trick unfortunately.

Here's what I've got now:

1 heavy duty power converter between US and European 115-230v I think.
1 UPS to deliver a constant stream of power to the WorkPrinter

S8Booster, can you fill me in?

It works great, and you can even hear the WorkPrinter working better than before when I used a "travel-transformer" which obviously didn't supply enough power.

Posting a brief system layout for Andreas´s WP Powersystem
It offers almost 100% voltage stability whatever the commercial power is from brown to blackouts, surges and sags. I will post more details later.

Roger,
How many watts does my WorkPrinter use? A sales person asked in an electirc store and since I knew the motor was changed I didn't know the answer.
Thanks.

Well, the safest way to figure what you need is to take the available wattage and divide by 100 (or available amperage and multiply by 100). So, if you had a 1000 watt lighting instrument, you would need a breaker that could handle 10 amps. Actually, that leaves a bit of headroom on power handling but it is a pretty safe and convenient way to look at it, especially if you don't know the age of the circuit breaker or associated wiring.

As this relates the WorkPrinter or CineMate, they need about 2 amps. In actuality, it's closer to 1.5 amps but 2 amps leaves some headroom for safety, depending on the efficiency of the transformer. So that would mean a draw of about 200 watts. Again, this is overestimated due to simplified math being applied but it will mean that you will have plenty of power without overloading your convertor. You need to look for something that will handle 150-200 watts or 1.5-2 amps on average.

My letter requesting help went out by fax to several UK places and a EE brother inlaw:


February 24, 2003

Dear Sirs,

Could you please help me power a rebuilt old film movie projector? It requires a voltage of 110 V and also requires 150 to 200 Watts of power. It runs on 60 cycles; at over 115 Volts, or so I am told, it would get too hot to continue long.
There are many dual converters on the internet, however, they do not specify the wattage provided; most only half the wall current and do not let 110 Volts be specifically output.
If you could provide one I'd purchase it.
Thank you very much,

Sincerely,

Michael A. Carter



PS: if any of you know of a shop please print and fax a copy to them.
e-mail me for my UK address to add into the post.
Thanks.

As far as I recollect the European standard is 230 volts +15% -10% or 207 to 264 volts! The UK used to be 240 volts + or - 10% which it was realised fitted into the European standard so that the bigest change was labelling from 240V to 230V.

Now Maplin do a nice 2A variable transformer DM96E for 50 quid. The input is 240V or 270V and the output 0-270V so so long as there is a voltmeter across the output you can easily adjust.

They also have a selection of 115/230 volt transforemers as well.

[studiocarter]

Thank you. That is just the thing, I guess, not being all so experienced in power supplies and all. Is it that an external voltmeter is used to check on the power supply settings? Then removed?
I found the web site.
Thanks again.

The European Standard should now be: 230v -6% +10% if nothing is altered recently. 240V for UK is gone as a matter of conformity to the common voltage standard for Europe.

Maplin customer service was called. The unit no. VR03 was recomended. Just plug and play. It does not go up to 250 volts and that is why I suppose. The other one is out of stock. No longer used?

We're getting close, keep plugging away, a strike is bound to happen soon.
