NOTES

1.

With input capacitor 22µF/50V (CHEMI-CON KY) 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 (0 LFM)

5.

To meet EN55022 Class A,B an external filter is necessary. Please contact factory

6.

This series can meet EN61000-4-4 by adding a capacitor across the input pins. Suggested capacitor: 22µF/50V (CHEMI-CON KY).

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