[Swansea Hackspace] bench power supply

[Andy Davies]

Hi Ceri

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.

I’m looking for something that is a complete unit such as https://www.ebay.co.uk/itm/Adjustable-Linear-DC-Bench-Power-Supply-0-50V-0-3A-Variable-CSI5003XE/222258220290?epid=1542954192&hash=item33bf9f4d02:g:H9sAAOSw5OpZr-V8

but it is really important that no flicker shows up on the video at a shutter speed of 50fps.

Many thanks

Andy

  That's a high voltage !!!!!!! 

  A simple current source circuit will work the best for LEDs 

  One of my first jobs was KRAZY high power LED lighting designer 

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

    PS It is also important that it does not induce flicker in the light as I will be shooting video with it.
