Full Description
OPUS Solutions 120W DC-DC smart power supply, PATENT PENDING, is designed specifically for ITX motherboards to be used in an automotive environment. This product brings a new dimension to your PC’s mobility. When you switch off the Power-ON lead the PC can go into shut down, standby or hibernate modes automatically.
The 120W DC-DC Power supply has a micro-controller that controls and monitors various functions of the power supply operation. It monitors automobile battery voltage to protect against deep discharge. The Power-ON lead is monitored to start the PC when the power is turned on and to implement a safe shutdown procedure. It controls and monitors motherboard signals to provide smooth power-up and power down sequences. In addition, it also responds to shut down, stand-by and hibernate modes.
The power supply can be programmed to shut down the PC after a delay of time. Its outputs are monitored to assure proper PC operation. A green LED indicator in the power supply continually indicates the power system status and health. It is also used for troubleshooting. There are features that are built-in for trouble-free and safe PC operation. The input power is protected against transients, load dumps and double battery during jumpstarts. The PC does not reboot during engine start or cranking. It also uses state-of-the-art technologies and the most advanced techniques to maximize efficiency, performance and reliability. Simply put, there is no other PC power supply like it.
