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.

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.
