DCA7.150 (150W)

Overview:
DCA7 is an intelligent Vehicle Triple output DC-DC power supply (PATENT PENDING) designed to power small form factor low power mother boards, Single board computers and peripherals that require 5V, 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 DCA7 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/trigger output of the DC-DC can be used to turn on/off slave devices such as head units, Audio Amplifiers, LCD monitors, DVD players, 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.

Features:
- 150 Watt output
- 12V and 24V system compatible
- High Efficiency DC-DC Power Supply (extended battery life)
- Built in auto shutdown
- Delayed shutdown timer
- Wide input voltage range
- On/Off power switch input
- Does not Re-boot PC during engine restart/cranking
- Load dump protected
- Start-up and shut-down voltage selection
- Automatic shutdown at low battery voltage to protect battery
- Built in diagnostics for troubleshooting
- Extended operating temperature range
- Wake on interrupt when ignition is off
- Remote/trigger output to turn on/off slave devices

Application:
- board computers, small form factor computers and LCD monitor
- LCD monitors that require regulated DC voltage in automotive application, etc.
