capacitor and 10 ? capacitor be connected in parallel from the +v out to the -v out pins for single output units and from each output to common for dual output units. 5. transient recovery is measured to within a 1% error band for a load step change of 25%. 6. short circuit protection is provided by a ?iccup mode circuit. 7. the switching frequency for 24 vdc output models is 285 khz. 8. operation at no-load will not damage these units. however, they may not meet all speci cations if operated below the speci ed minimum load. 9. it is recommended that a fuse be used on the input of a power supply for protection. see the model selection table above for the correct rating. model number input output ef?
