Reducing / Limiting power supply output.

Is it possible to restrict or otherwise limit the power from a high
voltage power supply? Specifically:

"Units need 18-24V DC and output a maximum of 1300 VDC at about 30mA
short circuit current"

Is there a way I can get this down to between 700 and 900 volts? Does
anyone know of any common consumer products that I could purchase and
remove the power supply from that would be in the 700 VDC to 900 VDC
range? The only thing that comes to mind for me is a bug zapper but I
have no idea what power levels are involved yet?

Thanks in advance,
Will

Maybe fix with:
R attenuator with resistors with proper voltage ratings.
or
Shunt current regulator

Or how about a new circuit?
Switcher (smps design) with step up transformer
or
Cap/diode multiplier running of line voltage. (no isolation)


For better suggestions, mention load detail. 700VDC @ what I?

How bout three 160 - 200V 5W zeners. as long as your load is below 30mA
