This external power adapter is for ONErack applications that do not utilize a ONErack power supply. 1RK-FAN-PSU

The ONErack is now ready for mission critical applications! This universal, powered mounting system already improves rack installation of small devices but now you can add redundancy to equipment, never before possible.  But not just redundancy – a whole lot of protective features for halfrack and smaller devices, like DC power conditioning, loadsharing, surge protection and resettable fuses.  The new 450w Dual Redundant, Hot Swappable Power Supply fits into any ONErack Chassis 4RU, 5RU and 6RU, which can hold up to 16 modules with up to 2 voltage selectors each. When using a ONErack Power Supply, each voltage selector can provide power @ 5v, 7.5v, 9v, 12v, 13.5v, 18v, & 24v -each up to 35 watts. tvONE’s patent pending design converts devices from any manufacturer into slide-in modules that can be installed quickly and cleanly. For service, just slide out a failed device, no cable ties, no guessing.  Close the front of your ONErack with a Fan cover and keep it all cool.  Up to 32 devices in just 4RU, redundantly powered and cooled!
