Posted by John Keller BLACKSBURG, Va., 12 June 2011. VPT Inc. in Blacksburg, Va., is introducing the DVPL0520S 20-amp DC-DC power converter module for rugged military and avionics power systems. The power electronics module is a non-isolated, synchronous, regulated buck converter that steps down power at the point of use with as much as 90 percent efficiency, VPT officials say. Power conditioning systems designers can use the DVPL 20-amp module alone or with several POL DC-DC converters all powered from one isolated high-power DC-DC converter. The power module offers:
-- as much as 20-amps of power output at 66 Watts;
-- operation from 5 volts nominal input;
-- as much as 90 percent efficiency;
-- fault-tolerant design with magnetic feedback;
-- no optoisolators;
-- output inhibit control;
-- low output noise;
-- size of 1.075 by 1.075 by 0.270 inches;
-- weight of 16 grams;
-- over current and short circuit protection;
-- operating temperature range of -55 to 125 degrees Celsius;
-- environmental screenings available, including MIL-PRF-38534;
-- meets MIL-STD-461C and MIL-STD-461D EMC requirements when used with VPT DC-DC converters and EMI filters; and
-- qualified to ISO-9001 and certified to MIL-PRF-38534 and MIL-STD-883.
