we have a project, for which we are designing Power supply.
Thing is
Input: 50 to 85V DC with Vin_nominal =72V DC
output1 = 12V@3A
Output2 = +/-24@1A
I have checked most of the manufacturers sites like TI,Linear tech,National semiconductors,Maxim-ic and other companies.
most of the companies are not supporting this much input voltge...mostly all are going upto max Vin = 72V .....
can u help in suggesting a way to me......
if it was a module also no problem.....
any method to reduce the Input voltage to around 50V without losing much power....
ours is a test equipment, these suplies will take lot of space...that too we can generate only one of the voltages 12 or 24 or -24 by using these modules...
so, we have to use 3 modules ...which is not practical......
from Powerone and wallindustries we have selected some of the modules, But same problem persists as we need to use saparate for each supply......
is there any remedy...like we can generate atleast +/-24 with one module and 12V with another one....
Hi Malli,
Maybe you have to select some synchronizable versions, than I believe too zhat their are in one modul or system to realize...
Eventually you can apply 3 individual modules, but with Power sequencer/"hot plug-in Switcher" for "at one time" get it on/off circuits.

Hi Malli,
Power One,s "CS2660-7R" eff.=82%,Inp.Voltage=28 to 140 VDC: 24V,2A & 24V,2A(Second output semi-regulated.)...
Is it nothing for you? **broken link removed**

Added after 4 minutes:
Or two times PSA 241.5-7iR, eff.93%,,Inp.Voltage=31-144V, has 24V,1.5A, smaller Modules: **broken link removed**
Hi malli,
I read yet an article over following Switcher, what maybe helps for you: 80-V DC/DC converter targets boost, flyback, SEPIC and inverting power supplies, has an On-Board 84 V/3.5 A Power Switch, The1000-piece price starts at 3.05 US Dollars each.... LT3898
