Notes

1

Specifications typical at Ta=+25℃, resistive load, nominal input voltage, rated output current unless otherwise noted.

2

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

3

We recommend to protect the converter by a slow blow fuse in the input supply line.

4

The M78SA series can meet EN61000-4-4 by adding a capacitor across the input pins. Suggested capacitor CHEMI-CON KY 330μF/100V.

5

That “natural convection” is about 20LFM but is not equal to still air (0 LFM).

6

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

7

Input voltage must be higher than output voltage set:>1.5V for 3.3V~5V and >3V for 6.5V~15V.

8

Specifications are subject to change without notice.
