POWER SUPPLIES JUPITER-MM 50 WATTS, DUAL OR QUAD OUTPUTS, RUGGED DESIGN Jupiter-MM provides competitively-priced, stable SPECIFICATIONS DC power for mobile PC/104 systems. The small INPUT magnetics and SMT components combined with Input voltage 7-30VDC slim heat sink design create a fully PC/104-compli- Transient protection 1500W transient voltage ant module that can be stacked above or below suppressor other boards. The dual-output JMM-512 has +5V Transient cutoff 31V nominal and +12V outputs, while the quad-output JMM-512- OUTPUT V512 adds -5V and -12V outputs. Output voltage/current See configuration table The input is protected against transients, and Output protection Current limit / short circuit the outputs have built-in protection against short protection circuits. Power circuits are cascaded, allowing Output ripple <50mV RMS all power to be utilized on the +5V output (10A) 50 watts output power (+5V output, 50% load) or shared across multiple outputs.
