<DIV>Hi Ceri</DIV>
<DIV> </DIV>
<DIV>I have three of these types for 6V (for powering a flashgun, 12V (for
stepper motors and LEDs)) and 24V (for a stepper motor on a linear rail.</DIV>
<DIV> </DIV>
<DIV>I’m looking for something that is a complete unit such as <A

<DIV> </DIV>
<DIV>but it is really important that no flicker shows up on the video at a
shutter speed of 50fps.</DIV>
<DIV> </DIV>
<DIV>Many thanks</DIV>

<DIV>That's a high voltage !!!!!!!

<DIV>A simple current source circuit will work the best for LEDs </DIV>

<DIV>If you can get a 40 or so Volt PSU.</DIV>
<DIV>then easy circuit. ..</DIV>
<DIV>But I do recommend a protection resistor too</DIV></DIV>
