need negative voltage to power PSU
I recent purchase a cheap power supply unit for $50.00 The unit requires -38 to -72 vdc to operate. How can I produce the that voltage from a car battery.
Here is the specs on the unit.
Electrical DC Voltage Input Range -38Vdc to -72Vdc
Current Input (Max) 30A at - 38Vdc per module
Power Output 750W
Current Output (Max)
(+5) 39A
(+3.3) 37A
(+12) 37A
(-12) 1.4A
(-5) 1.0A
Power Cable-AWG, Length
and Plug Type #10, 12 ft, 3 tinned leads
Input Receptacle Compaq
Please email if there is a solution.
Yikes! You've gone industrial!
There are plenty of DC-DC converters that can get you the right voltage but for that kind of current it's gona be expensive.
Also look at the lowest imput voltage, needs to be <9V if you want to keep it goin while starting you car
try searching for these
Lambda
Datel

If you come out talking sh1t don't try to turn around and wipe you azz.
Getting that voltage is not easy. In fact, it will be significantly easier and cheaper to just buy/build a supply that takes 12V as it's input.
