JMM-512 (DIAMOND SYSTEMS)

Jupiter-MM provides competitively-priced, stable DC power for mobile PC/104 systems. The small magnetics and SMT components combined with slim heat sink design create a fully PC/104-compliant module that can be stacked above or below other boards. The dual-output JMM-512 has +5V and +12V outputs, while the quad-output JMM-512-V512 adds -5V and -12V outputs. The input is protected against transients, and the outputs have built-in protection against short circuits. Power circuits are cascaded, allowing all power to be utilized on the +5V output (10A) or shared across multiple outputs. A shutdown control input is provided to enable remote shut-down of the supply. Power I/O connections are through convenient detachable screw terminals. All output voltages are also routed to their respective PC/104 bus pins. Power output LEDs provide a convenient indication of power supply operation. The cascade configuration of the power conversion circuitry enables the full output power (5 or 10 Amps) to be supplied to the +5V line if needed. The +12 and -12 outputs derive from the +5 output, and the -5 line derives from the -12. The total power available on any output is the difference between that output’s maximum rating and any power consumed by outputs further down the chain.
