NOTES

1.

Din Rail Mounting is available for this series. To indicate Din Rail bracket add –D to model number. Ex. DCWIM20-24S51C-D

2.

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

3.

Natural Convection is about 20LFM but is not equal to still air (0 LFM).

4.

It is recommended to protect the converter by a slow blow fuse in the input supply line.

5.

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

*Due to advances in technology, specifications subject to change without notice.
