(R) CHASSIS MOUNTING KITS SINGLE, DUAL, AND TRIPLE OUTPUT DESCRIPTION In applications where Power-One DC/DC products do not fit an existing 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 180F (100VDC) input capacitor as well as output capacitance with decoupling. Socketed pins provide for direct installation of DC/DC converters to the chassis mount kit. See Figure 1. Input and output connections are detailed in Table 2 and Table 3. 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 Mounting Reference Chart. 4) Connect via electrical connections as shown in Table 2 and Table 3. 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 converters with lower input currents, are complete with socketed PC board, 1.5 Ampere fuse, 180F (100VDC) input capacitor, and barrier strip connector. CM2B chassis mounting kits are complete with socketed PC board, 4.0 Ampere fuse, 4.35" (110.49mm) 180F (100VDC) input capacitor, and barrier strip connector. Chassis mount kits are not available for the following product series: DSP1, DSN17, and DFC25. 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.
