Seal around terminals is not hermetic. Do not immerse units in any
liquid.

Heat Sink Option
The 27-30 Watt Triple can be ordered with a “-I” configuration
which provides 3 inserts on the top surface of the case for
attaching a heat sink.
When ordered with an “-HS”
configuration, CALEX will ship the converter with the heat sink
attached. The CALEX heat sink was specially developed for
this model and will reduce the case temperature rise to below
3.3°C/W with natural convection and even lower with moving
air.
Customer installed heat sinks may also be used. It is
recommended that only liquid heat sink compound be used on
the heat sink interface. Avoid so called “Dry” pad heat sink
materials. In our experience these materials are actually
worse than using no compound at all.
Chassis Mounting Kit - MS9
The MS9 chassis mounting kit allows for direct wire connection
through two barrier strips. The MS9 may be conveniently
attached to a chassis by using the 4-0.156 inch diameter
mounting holes provided in each corner.
Although the MS9 comes with solderless sockets, it is
recommended that the converter be soldered to the mounting
kit for improved reliability under severe environmental or
vibration conditions.
Typical Application
Figure 1 shows the recommended connections for the 27-30
Watt Triple DC/DC converter.
A fuse is recommended to prevent unlimited current flow in
the event of a system failure and to protect the DC/DC
converter input circuit.
