Notes:
1. The specifi ed maximum capacitive load is for each output. A 2W version of this module is also available
2. Cross regulation is measured with the main output set at 100% load. The second output is For more information see the MH200RW series datasheet.
varied from 75% to 100% load.
3. When measuring output ripple, it is recommended that an external 0.47 µF ceramic capacitor Or call the factory at 781-344-8226
is connected from the +VOUT to the -VOUT pins. If the application is noise sensitive; connecting
a low ESR 3.3 µF capcitor should be used. This capacitor should be mounted as close to the Mechanical Dimensions
converter as possible.
4. Transient recovery is measured to within a 1% error band for a load step change of
25%.
5. Output overload protection is provided by a fold back current limiting circuit with
auto-recovery. A long-term overload could damage the unit.
6. To meet the specifi ed EN 61000-4-4 and EN 61000-4-5 limits, an external capaci-
tor must be connected across the input pins of the module. A 220 µF/100V capacitor
is recommended. This capacitor should be mounted as close to the module as possible.
7. Operation at no load will not damage these units.
8. 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.
