Start up time is measured at nominal input and with a constant resistive load. For heatsink option, add suffix “H” to model number (i.e. MI2512S-05RW-H) 2. When measuring output ripple, it is recommended that an external 1 µF capacitor and 10 µF capacitor be connected in parallel from the +VOUT to the -VOUT pin for single output unis; or from each output to common for dual output units.. 3. Transient recovery is measured to within a 1% error band for a load step change of 25%. 4. Short circuit protection is provided by a “hiccup mode” circuit. 5. Operation at no-load will not damage these units. 6. 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.
