NOTES

1.

With an input capacitor 22µF/50V for input voltage >28VDC, input voltage allows 32VDC, max.

2.

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

3.

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

4.

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

5.

This series can meet EN61000-4-4 by adding a capacitor across the input pins. Suggested capacitor: CHEMI-CON KY 330µF/100V.

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