Product Model：PWR-H2-ATX

Product Description:

PWR-H2-ATXThe power supply module is referred to the wide voltage design of on-board computerATXPower supply,In5.5～28VThe input voltage range，Can be a stable output12V、5V、3.3V、-12V、 5VSBAn equal voltage，Maximum output power250W，SupportATX 20PAndATX24PThe motherboard，Compatibility，Protection function。

Module8BitMCUControl the on-off time delay andATX/Power-off time series，In strict accordance withINTELTheATXPower supply standard design。12VThe output has the United StatesLinearThe company'sLTC3780As the control chip，Implementation of step-up/step-down function，In5.5～28VThe power supply voltage range stable output12V。

ModuleITPSThe on-off time delay function，On-board3Group jumper can set a variety of different modes of operation and shutdown delay、Power-off time delay，Support of computer automatic on/off。The vehicle ignition(ACCOn)After5Second power supply to work，Effectively avoid the engine start-up of the transient voltage and a large load to the battery of the injury。The vehicle is turned off(ACCPower-off)After a certain time(Jumper settings ofOff delay)Re-ignition，Computers are not restart or shut down，To avoid the accident off or short time off the computer frequent on/off。The vehicle is turned off state，Beyond the jumper settings of the shutdown delay(Off delay)After，Power source automatic switch-in transmission power-off instruction to the motherboard，Turn off the computer。Beyond the jumper settings of compulsory turn-off time(Off delay)After，Closed5VSBPower supply，Module enters the low-power standby mode。In the low-power standby mode，Standby current is less5mA，Don't have to worry about light car battery，Results gave the car can't fire。

Wiring diagram：

J1：ACC，Pick up the carACCThe signal line。Household or a test andJ3On。NoteACCDon't Connected with the cathode of the power supply does not work。

J2：GND, The negative input electrode，A car battery negative electrode

J3：VIN, Enter the positive electrode，A car battery positive electrode

J5：ATX 20PThe power supply output socket，With the support20-24PWire coupled to the motherboard

J7：Hard power output socket

J6：ATX 4PThe power supply output socket，With the support4PWire coupled to the motherboard。

LED1：Supply Status Indicator。ACCTurn on or off the flashes after10S，Power supply to a job after its been solid。

LED2：Power supply working indicator，Boot the computer will be activated at，Shutting down the machine off

JP2：REM（The power amplifier mute）Output，Start-up and shutdown when outputs a low-level(0V)，During normal operation of the output high level(12V)，Can be coupled to an external power amplifier (PA)REMEnd，To avoid the computer to generate the on/off of the noise

JP3：The motherboard of the on/off control line output。With the support2The needle black dupont xian received motherboardPWR_SWOn，For controlling the computer automatic on/off。Manual on/off when，I should be grateful if you would have on the motherboard PWR_SWA panel boot button，J4Don't answer。

JP1: Shut down the delay time setting jumper，The following table：
