USER NOTES
Input Voltage
The recommended operating maximum DC input
voltage is 40V inclusive of the ripple voltage.
Case Grounding
The module case is internally connected to pin 2
and pin 3.
The PCBarea below the module canbeused asan
effective sixth side shield against EMI.
Thermal Characteristics
The case-to-ambient thermal resistance of all the
GS-R400/2 modules isabout 8
°
C/W.This produces
a 32
°
C temperature increase of themodule surface
for 4W of internal power dissipation.
Depending on the ambient temperature and/or on
the power dissipation, an additional heatsink or
forced ventilation may be required.
Input Impedance
The module has an internal capacitor connected
between the input pins in order to assure PWM
stability. This capacitor cannot handle large values
of high frequency ripple current and it can be per-
manently damaged if the primary energy source
impedance is not adequate.
The useof an external low ESR, high ripple current
capacitor located as close the module as possible
is recommended.
Suitable capacitors should have a RMS current
capability of 2.5A
RMS
with a working voltage of 50
V
DC
and an ESR of 0,1
at 100kHz. When space
is a limitation a 22
μ
F ceramic multilayer capacitor
must be connected to the module input pins.
Output Voltage Programming
The GS-R400V/2 outputvoltage is programmed by
using a resistor.
The resistor must be locatedvery close the module
and the PCB layout must minimize injected noise.
The value of the resistor is calculated by using the
following formula:
R
v
=
2.67
V
o
5.1

k
V
o
can be adjusted between 5.1 and 24V.
Module Protection
The modules are protected againstoccasional and
permanent short circuits of the output pins to
ground. During short circuit (when the output cur-
rent exceeds the maximum value) the output is
automaticallydisabled.After afixed timethemodule
starts again in a soft mode. The cycle is repeated
until the short circuit condition is removed.
The module can be permanently damaged if the
case temperature exceeds 85
°
