1. |
Specifications typical at Ta=+25°C, resistive load, nominal input voltage, rated output current unless otherwise noted. |
2. |
These power converters require a minimum output load to maintain specified regulation. |
3. |
Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed. |
4. |
All DC/DC converters should be externally fused at the front end for protection. |
5. |
Other input and output voltage may be available, please contact factory. |
6. |
All specifications subject to change without notice. | |
