Diamond Systems JUPITER-MM-5000 3.3V/5V/12V DC/DC PC/104-Plus Extended Temperature Rugged Power Supply

Larger rugged stacks with fast processors and several I/O boards can draw more than a 50 W supply provides, and on vehicles they also need control over how and when each rail comes up. The JUPITER-MM-5000 is Diamond Systems’ high-power PC/104-Plus power supply, delivering up to 218 W from a 7 to 34 V DC input that covers 12 V, 24 V and 28 V systems.

Full JMM-5312 models give +5 V at 20 A, +12 V at 8 A, +3.3 V at 5 A, +5 V standby at 1 A and +3.3 V standby at 0.1 A; JMM-5012 models drop the 3.3 V rails for 196 W, and JMM-5000 models give +5 V only at 100 W. Diamond quotes 92 to 94% efficiency, 0.35% maximum droop and 12 mV peak-to-peak ripple at 5 V with a 12 V input, and ±0.5% stability across -40 to 85 °C.

Intelligent models add a system controller on USB, with benchtop software and a programming library. It provides individual on/off control and monitoring of each rail, output sequencing and slew rate, millivolt-level voltage adjustment, input monitoring, fault handling with interrupts, hiccup-mode restart and min/max logging. A dual input with automatic cutover turns the supply into a UPS when a battery is fitted. Input protection covers over and under voltage, reverse polarity, surges and transients. For smaller stacks, the JMM-512 gives 50 W, and the JMM-7312-UPS adds MIL-STD filtering and a supercapacitor UPS input at 40 W.

Bus options are 16-bit ISA for PC/104 or ISA plus 32-bit PCI for PC/104-Plus, with heat spreader or heat sink cooling and locking screw terminal blocks. Extended temperature operation from -40 to 85 °C is tested and guaranteed, and the JUPITER-MM-5000 is RoHS compliant. We supply and specify each model as Diamond builds it.
