DESCRIPTION
In applications where Power-One DC/DC products do not fit an exist-
ing circuit board, Power-One chassis mount kits allow the installation
of most DC/DC converters directly to frames, fixtures, and chassis. To
improve converter performance and reduce circuit noise, chassis mount
kits provide a 180µF (100VDC) input capacitor as well as output capac-
itance with decoupling. Socketed pins provide for direct installation of
DC/DC converters to the chassis mount kit.
Table 1, the DC/DC Chassis Mounting Reference Chart describes the
application of single, dual, and triple series DC/DC converters to the
chassis mount kit. The CM2A chassis mounting kits, designed for con-
verters with lower input currents, are complete with socketed PC board,
1.5 Ampere fuse, 180µF (100VDC) input capacitor, and barrier strip
connector. CM2B chassis mounting kits are complete with socketed
PC board, 4.0 Ampere fuse,
180µF (100VDC) input capacitor, and
barrier strip connector. Chassis mount
kits are not available for the following
product series: DSP1, DSN17, and DFC25.
Electrical connection to the chassis
mount kit is via a barrier strip with
Molex compatible pins (Molex Series
2139 or Series 6442 connector).

CHASSIS MOUNT KIT SELECTION:
To properly select the correct chassis mount kit is as follows:
1) Select DC/DC converter from Product Selection Guide.
2) Note the required series and input voltage of DC/DC converter.
3) Verify usage of selected converter series as per Table 1, DC/DC Chassis
4) Connect via electrical connections as shown in Table 2 and Table 3.
EXAMPLE:
A single output DFC10 with a 48 Volt input will require a CM2A1 chassis mount kit.
A dual output DFC10 with a 24 Volt input will require CM2B2 chassis mount kit.
