[sci.electronics] High isolation switching power supply

lalonde@ireq.hydro.qc.ca (Francois Lalonde) (10/30/90)

We are looking for a switching power supply with special caracteristics.
The output must be stable with large voltage variation at input.

Input range:                     70VDC to 700VDC
Output volts:                    +15VDC and -15VDC
Output current:                  about 500mA
_________________________________________
Isolation between IN and OUT:    5000VDC
_________________________________________
Isolation between IN and Ground: 5000VDC
_________________________________________

Maximum temperature:             100 celcius

This will be instaled on a rotating machine and must withstand 
acceleration and vibrations.
