4.12 Auxiliary power (AUX)
¡
The unit has the auxiliary power (AUX: 5V1A) in CN1 to provide
for the remote ON/OFF and external circuits.
¡
When the Global inhibit function activates, the following derating
for the AUX is required.
Derating for AUX: Io(AUX)
[
0.5A
¡
The AUX circuit(AUX, AUXG) is isolated from the input, the output,
the FG, and other function terminals except GI1.
¡
If the output current of the AUX exceed 1A, the unit might be dam-
aged or malfunction.
When the DC-DC converter is connected to the AUX, the cur-
rent might be severalfold of the normal current when starting up.
Please check the current.
¡
The maximum external capacitor to the AUX is 47μF.
