parvus Unveils Embedded PC Card with Dual Fans, Temperature Sensor

6/5/2003 - parvus Corporation announced its PC/104-Plus Power Interface board, a dual-function embedded PC card designed to convert DC voltages for output to the PC/104 (ISA) and PC/104-Plus (PCI) buses, while also providing forced air circulation to embedded systems. The board is priced at $187/each in orders of 100+ units.

Integrating an onboard 3.3VDC regulator, the PC/104-Plus Power Interface generates +3.3Volts (for up to 6Amps of current) from +5VDC and routes power through the PC/104-Plus header for PC/104-Plus peripherals that require +3.3VDC, such as network routers, FireWire, DSP, video and other high performance PC/104-Plus I/O cards. The board also routes 5 and 12 DC output voltages through the PC/104 bus or from an external power source (using its onboard screw terminal blocks), as well as routes 12 and +5VDC for the PC/104-Plus bus.

In addition to voltage conversion, this PC/104-Plus form factor (3.550" x 3.775") module integrates a temperature sensor and two onboard fans to monitor thermal conditions and provide air circulation for enclosed PC/104 embedded systems. Capable of thermostatic functionality, the board's two ball-bearing fans can be turned off and on, based on changing thermal conditions, to extend fan life and conserve power when not in use. In a sealed enclosure, the board can even reduce or eliminate the need for outside air exchange. Air is driven in a push-pull circular cooling pattern around the module and adjacent PC/104 cards.

parvus Corporation also offers 20, 35, 50, 75, and 90 watt PC/104 power supplies that can be used together with this product to supply it with 5/12Vdc. Models are available with either single, triple or quad output voltages and typically feature input/output voltage protection, multiple power connectors, battery charging circuits, onboard temperature monitoring, and intelligent shutdown.

parvus Corporation is a leading manufacturer and systems integrator of modular embedded computer boards, enclosures, displays and systems based on the PC/104 circuit board standard. Its rugged, embedded PC products offer commercial-off-the-shelf (COTS) solutions ideal for avionics, military, medical, industrial, and transportation OEMs. For more information, visit or call 801-483-1533.
