Opus Solutions DCA5.150 is an intelligent vehicle single + standby output DC‐DC power supply (PATENT PENDING) designed to power small form factor low power mother boards, Single board computers and peripherals that require 12V and 5V Stand‐by power. The 12V output can be configured to provide 12V to 20V output with 1V increment. The output voltage is configured with jumpers in the DC‐DC.
The DCA5.150 DC‐DC power supply has a micro‐controller that controls and monitors various functions of the power supply operation. It monitors vehicle battery voltage to protect against deep discharge. The ignition lead is monitored to start the PC when the ignition is turned on and to implement safe shutdown procedure. It controls and monitors motherboard signals to provide smooth power‐up and power‐down sequences. It is compatible with ATX ACPI power management specifications.
The power supply can be configured to shut down the PC after a predetermined delay of up to 120 min. The power supply outputs are monitored to assure proper PC operation. Wake on interrupt feature in DC‐DC together with Wake on LAN function on motherboards/SBC can be used to access the vehicle/mobile PC over wireless network without turning on the ignition switch for up to 20 min. at a time. This feature is useful for updating, uploading and down loading data/files of the car PC remotely. A green LED indicator in the power supply continually indicates the status and health. It is also used for troubleshooting.
Remote output of the DC‐DC can be used to turn on/off slave devices such as head units, Audio Amplifiers, LCD monitors, Two way radio units, etc. Delayed turn on is implemented to prevent thump‐from Audio systems.
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 conditions. The PC does not reboot during engine start or cranking.
