PC/104 DC/DC Power Supplies

Diamond offers a wide selection of rugged, wide-temperature, PC/104-sized DC/DC power supplies offering options of up to 218W output power, multiple output voltages, and fixed and variable voltage inputs.

PC/104

Jupiter-MM

This rugged, extended-temperature DC/DC power supply is designed specifically for air and ground vehicle applications. It consists of a PC/104 form factor module with complete DC-DC voltage regulator circuitry, heat sink, input and output connectors, power-good indicator lamps, and both 8-bit and 16-bit PC/104 bus headers. Input voltage range is 7 to 34VDC, making it suitable for use with both 12V and 24V systems.

Output power is provided directly onto the PC/104 bus connectors, as well as on an auxiliary connector for external tapping. Both dual output (+5, +12) and quad output (+5, +12, -5, -12) versions are available. Up to 10 amps can be provided on the +5 output, or the 50 watts of total power can be distributed across the 4 outputs.

The low-profile SMT design guarantees that you can add other PC/104 modules on top of this board without any worries of mechanical interference. Simply stack your CPU and other cards on top or below the power supply module to provide power to your PC/104 system.

Surface Mount Components
To the maximum extent possible, surface mount components have been used in the design, to lower the profile and improve ruggedness. An additional benefit to SMT technology is the improved ability to use the PCB planes as a heat sink.

High Efficiency, High-Frequency Design
Efficiency is as high as 92 percent, lowering input power requirements as well as heat generation. The 200KHz switching circuit allows the use of smaller inductors, reducing size and weight and allowing the board to fully fit within the PC/104 height requirements.

Advanced Heat Sink Technology
A new compressible thermally-conductive material mounted under the aluminum heat sink makes it possible to wick heat away effectively from varying height components. Also, the use of surface mount components and careful PCB design enhance the dissipation of heat through the PCB planes.

Remote On/Off Control
The supply can be turned on and off with an external contact closure through an auxiliary connector.

   

Jupiter-MM-LP

Jupiter-MM-LP (JMM-LP) is a low-cost DC/DC power supply ideal for PC/104 applications with lower power requirements. This supply is the lightest-weight PC/104 DC/DC supply available anywhere, due to the fact that it requires no heatsink. Extended temperature rating is included at no additional charge, making Jupiter-MM-LP a true bargain compared to competitive products that require an additional charge.

Output Power
JMM-LP provides 25 watts of total output power with output voltage of 5VDC +/-5% at 5A max. Input voltage range is 7 to 30VDC, making it suitable for use with both 12V and 24V systems.

No Heat Sink Required
Due to a new improved power supply circuit design, we've eliminated the heat sink, reducing the board's weight to the absolute minimum. JMM-LP is ideal for use in small enclosures such as our Pandora, since no forced-air or other cooling is required to maintain safe operation.

True PC/104 form factor
The low-profile SMT design fits completely within the PC/104 module specifications and guarantees that you can add other PC/104 modules on top of this board without any worries of mechanical interference. Simply stack your CPU and other cards either on top or below the power supply module to provide power to your PC/104 system
