GS-R400 FAMILY
is a limitation, a 22碌F ceramic multilayer capacitor
must be connected to the module input pins.
Output Voltage Programming
The GS-R400V and GS-R400VB output voltage is
programmed by using a resistor (see pin function
table and fig. 4). The resistor must be located very
close the module and the PCB layout must
mimimize injected noise. The value of the resistor
is calculated by using the following formula:

can be adjusted between 5.1 and 40V.
Current Limiting Programming
The GS-R400VB current limiting is programmed by
using a resistor (see pin function table and fig. 4).

following formula:

Module Protection
The modules are protected against occasional and
permanent short circuits of the output pin to ground,
as well as against output current overload.
When the output current exceeds the maximum
value, the output is automatically disabled. After a
fixed time the module starts again in a soft mode.
The cycle is repeated until the overload condition is
removed.
A crowbar output overvoltage protection is activated
whenever the output voltage exceeds the nominal
output voltage by more than 25%.
