New PWR-21-11 and PWR-22-11 Cards Provide Isolated DC/DC Power Conversion, MIL-STD-1275 / 704 / 461 Power Conditioning and EMI Filtering

Amaro (ITALY) and Salt Lake City (USA), 23 August 2012 – Eurotech subsidiary Parvus announces two new rugged embedded DC/DC power supply boards with built-in MIL-STD power conditioning and EMI filtering for military ground vehicles and aircraft installations. The rugged PWR-21-11 (PC/104-Plus form factor) and PWR-22-11 (PCI/104-Express form factor) galvanically isolated DC/DC converter modules provide 100 watts of combined power output (+3.3V, +5V, +12V) and come equipped with MIL-STD-461 EMI filtering and transient protections for demanding 250V spike and 100V surge requirements under MIL-STD-1275. They support an 18-36V DC input range for 24/28VDC applications and typically eliminate the need for additional in-line power conditioning/EMI filtering devices in military embedded systems.

Featuring a rugged mechanical design, these small form factor (3.550” x 3.775” / 90x 96 mm) cards are designed to be used in a PC/104, PC/104-Plus, PCI-104, PCIe104, or PCI/104-Express embedded system stack, operate without any active cooling over extended temperature ranges (-40 to +85C per MIL-STD-810G), and provide resistance to high levels of shock and vibration (per MIL-STD-810G fixed wing jet, rotary aircraft, and tracked ground vehicle conditions). A tribute to their robustness and versatility, the PWR-21-11 and PWR-22-11 power supplies are integrated into various Parvus MIL-STD-810/1275/704/461 qualified DuraCOR mission computers, DuraNET Ethernet switches, and DuraMAR mobile IP router subsystems.
