Cherokee Intros CNS411 400W DC/DC Converter

July 11, 1999 by Jeff Shepard

Cherokee International LLC (Tustin, CA) has announced the introduction of a PC platform 400W dc/dc converter with five outputs for disk drive and logic circuits. The CNS411 power supply's high-end industrial design is intended for the telecommunications environment operating from a -48Vdc bus. The CNS411 power supply is a fully enclosed hot-insertable dc/dc power supply requiring no external filtering or heat sinking. Operating from a -36V to -72V input (-48Vdc nominal), the unit delivers 400W of continuous output power at an efficiency of 75 percent. Maximum continuous output power ratings for the CNS411 model are +5V at 30A, 3.3V at 28A, +12Vat 14A, -12Vat 1A and -5V at1A. Operating features include remote sense (V1 & V2), dc power good signal and LED indicator, over-temperature protection, over-current and over-voltage protection, and single wire current sharing on the high current 3.3V and 5V outputs. Line and load regulation is +/-5 percent for V1 output over the entire input range. The CNS411 has a integral ball bearing fan, front panel mounted handle and green dc ok LED indicator. The converter measures 7.38" x 6.9" x 3.67" and weighs approximately 3.7 lbs. Operating temperature is from 0 to +50 degrees C with no derating. Safety agency recognition and compliance is to UL1950, CSA22.2 and TUV EN60950. Unit pricing in OEM quantities is $195, delivery lead time 6 weeks.
