derating curve     notes : 1. specifications typical at ta=+25°c, resistive load, nominal input voltage, rated output current unless otherwise noted. 2. transient recovery time is measured to within 1% error band for a load step change of 75% to 100%. 3. these power converters require a minimum output load to maintain specified regulation. 4. operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed. 5. all dc/dc converters should be externally fused at the front end for protection. 6. other input and output voltage may be available, please contact factory. 7. to order the converter without remote on/off function, please add a suffix -n (e.g. mkw3021-n). 8. all specifications subject to change without notice.
