1-General
The TETHYS 30W series is a full family of highly
configurable DC/DC low profile power module
designed for direct implementation on high
density printed circuit boards designed for
aerospace, military and high-end industrial ap-
plications. This module uses a high frequency
fixed swiching technic at 480 KHz providing ex-
cellent reliability, low noise characteristics and
low profile package. This model is available with
nominal input voltages as 12 or 28 volts in range
of 9-36 or 16-40 volts. The serie includes
thousands of output configuration from single,
bi up to six possible output voltages in choices
of 3,3, 5, 12, 15, 24 volts with trim and sense
functions for output voltage adjustment.
No external heatsink is required for the for CGDM
series to supply 30W output power over the
case temperature range of -40°C up to 105°C.
All the modules are designed with LC network
filters to minimize reflected input current ripple
and output voltage ripple.
2-Product Selection
The modules include undervoltage lock-out, a
permanent short circuit protection an output
overvoltage protection and a thermal protection
to ensure efficient module protections.
The soft-start allows current limitation and
eliminates inrush current during start-up. The
short circuit protection completely protects the
module against short-circuits of any duration by
a shut-down and restores to normal when the
overload is removed. The thermal protection is
adjusted to 110°C and protects the module
against overheat.
The inhibit function is commanded with a low
logic level and disables the module for applica-
tions requiring on/off operations.
The design has been carried out with surface
mount components and is manufactured in a
fully automated process to guarantee high
quality. Each module is tested and burned-in
with a GAIA Converter automated test
equipment.

8-1 Module Compliance with MIL-STD-461C/D/E Standards
To meet the latest US military standards MIL-STD-461D/E (and also the MIL-STD-461C) requirements and in particular the
conducted noise emission CE102 (and also CE03) requirements, Gaïa Converter can propose a stand-alone ready-to-use EMI
filter module. This EMI filter module has to be used together with a common mode noise capacitance Cc (10nF/rated
voltage depending on isolation requirement) connected between Gin and Gout.
EMI Filter module reference : FGDM-2A-50V.
Please consult EMI filter datasheet for further details.
