USER NOTES
Input Voltage
The recommended operating maximum DC input
voltage is 46V inclusive of the ripple voltage.
Remote Sensing
The remote voltage sense compensation range is
for a total drop of 500mV equally shared between
the load connecting wires. It is a good practice to
shield the sensing wires to avoid oscillation.
Each sense input must be connected to its compan-
ion output power pin when the remote sense capa-
bility is not used (see fig. 1).
Case Grounding
The module case is isolated from the electrical
circuit of the switching regulator. It can be grounded
using the 4 corner pins.
The PCB area below the module can be used as an
effective sixth side shield against EMI.
Thermal Characteristics
The case-to-ambient thermal resistance of all the
GS-R400 modules is about 5
°
C/W. This produces
a 50
°
C temperature increase of the module surface
for 10W 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 use of 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 100 kHz. When space
