If remote sense is not being used, the +Vsense should be connected to its corresponding +OUTPUT and likewise the sense should be connected to its corresponding -OUTPUT. Triple outputs requires a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specifications Load regulation for triple output: Main output (V1): 10 to 100% with 10% to 100% balanced on auxiliaries. Auxiliary outputs (V2 and V3): 10% to 100% balanced on all outputs. Cross regulation for triple output: Main output 100% load, auxiliary 100%, other auxiliary 25% to 100%. Auxiliary outputs (V2 and V3): main output 100% load, auxiliary 100%, other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other auxiliary 25% to 100%. The models of FEC40-XXD3305 are specified with a 1uF ceramic output capacitors. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V/24V models. Astrodyne suggests: Nippon chemi-con KMF series, 220µF/100V, ESR 9OmÙ. Simulated source impedance of 12uH. 12uH inductor in series with +Vin. The ON/OFF control pin voltage is referenced to negative Input.
