NOTES

1. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.

2. The DMW series requires a minimum output load to maintain specified regulations. Operation under no-load condition will not damage these devices;

however they may not meet all listed specifications.

3. All DC/DC converters should be externally fused at the front end for protection.

4. Other input and output voltages may be available, please contact factory.

5. Only positive control logic remote On/Off is available. To order the converter with positive remote on/off add the suffix “RC” to the part number.

6. To order the converter with EN55022 Class A function, please add the suffix “A” to the part number.

7. To order the converter with a heatsink please add the suffix “HS” to the part number.
