Designed for systems employing distributed high-voltage dc power architectures and for custom off-line power supplies, the PAF600F280 family of 600W, full-brick dc/dc converters operate with a nominal input of 300V and an input-voltage range from 200V to 400V. The converters are rated up to 50A and are available with 12V, 24V, 28V, and 48V outputs and efficiencies as high as 91%. Each model is adjustable between -40% to +20% of nominal output, eradicating the need for custom modification. The units measure 2.4" x 4.6" x 0.5" and operate in temperatures from -40°C to +100°C with either convection or forced-air cooling. Features include over-current and over-voltage protection, remote sensing, output adjustment trim, remote on/off, current sharing, a converter-good signal, and auxiliary voltage. Additionally, the converters carry CE, UL60950, CSA60950, and EN60950 approvals. Prices start at $172 each/100. LAMBDA, San Diego, CA. (800) 526-2324.
