[Sneap] High Voltage Isolated Power Supply

[Arthur Haberl]

High Voltage Isolated Power SupplyFor an isolated detector power supply, why not use a flood lamp and solar cells?  
For a 12 VDC battery charger, see http://www.siliconsolar.com/12v-Solar-Battery-Charger-3W-p-16280.html 
If you must have 115VAC, add a converter such as http://www.siliconsolar.com/75-150-Watt-Power-Inverter-p-16547.html 
The converter might need larger solar cells.

If you want to do the power supply in your own design, use a miniature converter such as http://www.emcohighvoltage.com/ourprods.htm

  A group here would like to build a ~50 kV isolated power supply to provide a variable dc voltage to a detector.
  I am therefore looking for a 50 kVDC line isolating transformer or a step down transformer with 50 KVDC
  insulation between primary and secondary sides - or perhaps someone out there has a more elegant solution.
  The power required on the HV deck is tiny - less than a watt I guess.  They want this thing to be "portable" - at least with a hand truck.
  Any ideas?
  Regards,
  - Chris
