Notes :
1. Specifications typical at Ta=+25], resistive load,
nominal input voltage, rated output current unless
otherwise noted.
2. Transient recovery time is measured to within 1%
error band for a step change in output load of 75%
to 100%.
3. Ripple & Noise measurement bandwidth is 0-20
MHz.
4. These power converters require a minimum output
loading to maintain specified regulation.
5. Operation under no-load conditions will not damage
these modules; however, they may not meet all
specifications listed.
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.

6. All DC/DC converters should be externally fused at
the front end for protection.
7. Other input and output voltage may be available,
please contact factory.
8. To order the converter with Remote On/Off function,
please add a suffix -RC (e.g. MKW2521-RC).
9. To order the converter with EN55022 Class A
function, please add a suffix A (e.g. MKW2521A).
10. Specifications subject to change without notice.
