Often times, rushing into installing the unit can result in serious damage to your FT-PR150B-ITPS board, computer and probably your car’s electrical system. The FT-PR150B-ITPS board has several wires that need to be installed in various places. When installing, always double check the polarity of your wires with a voltmeter. Avoid using the cigarette plug as a power source, often times the contacts are not capable of delivering high current to your PC. 1.0 Introduction Thank you for purchasing the FT-PR150B-ITPS power sequencer / vehicle ATX power supply. The FT-PR150B-ITPS was designed to work with a wide variety of main boards such as the VIA mini-ITX motherboards as well as Pentium-M Celeron or full power P4 systems. 1.1 FT-PR150B-ITPS Logic Diagram Model： FT-ITPS0B- Revision： A0 Page： 第 2 页 共 9 页 FT-PR150B-ITPS 1.2 FT-PR150B-ITPS Connection diagram FT-PR150B-ITPS, top view Power Input Connectors J1 Battery + (un-switched battery, positive) J3 Ignition (switched battery, positive.

Mode “0” is regular ATX power supply mode, no power sequencing provided, can be used for non vehicle applications. Avoid using HARDOFF = Never, can severely discharge your battery if PC. Suggested modes are: 1, 2, and 4. Model： FT-ITPS0B- Revision： A0 Page： 第 4 页 共 9 页 FT-PR150B-ITPS 1.2 Power challenges in a Vehicle PC The 5V Standby Problem: One of most difficult tasks of operating a PC in a vehicle is power consumption while the computer is OFF. Even when your computer is OFF, it will still consume about 100mA on the 5V rail. All power supplies provide 5VSB (5V standby) so that the motherboard can issue at least a PSON signal. When the computer is in the suspend mode, it will consume even more power, because the RAM needs to be powered at all times. No matter how big your battery is, it will eventually drain your battery in a matter of days. FT-PR150B-ITPS User Guide Page 2 The FT-PR150B-ITPS is addressing these issues by cutting off the 5VSB rail after a pre-defined amount of time (see jumper chart, HARDOFF). When 5VSB is always active (HARDOFF=Never), FT-PR150B-ITPS constantly monitors the battery levels. When battery level drops below 11V for more than one minute, FT-PR150B-ITPS will shut down and re-activate only when the input voltage is > 11. Engine Cranks, under-voltage and over-voltage situations. Another difficult task is maintaining stable 3.3V, 5V, 12V and -12V power to your PC. While car batteries are rated at 12V, they actually provide voltages in between 7-11V (engine cranks) or as high as 80 volts (load dump). Most of the times, your battery will stay at 13.5V (while car is running) but extra precautions need to take place in order to prevent such situations. FT-PR150B-ITPS can operate as low as 8V and as high as 28V while providing strict regulation on all rails along with input voltage clamping and reverse protection. Loud amplifier pops when PC starts. If your PC is connected to your car amplifier, you will hear a loud pop when the computer is first started. The FT-PR150B-ITPS has an ‘anti- thump’ Model： FT-ITPS0B- Revision： A0 Page： 第 5 页 共 9 页 FT-PR150B-ITPS control that will keep your amp OFF while the PC starts. Simply connect J6 to your amplifier remote control pins to activate the ‘anti-thump’ feature. 2.0 Mode of operation The FT-PR150B-ITPS performs several timing routines and takes actions as follows:(NOTE: When all config jumpers are removed, FT-PR150B-ITPS will be in the “dumb PSU mode”,no ignition timing, no HARDOFF. FT-PR150B-ITPS will send a gratuitous “ON” pulse to the M/Bwhen power is applied for the first time. Do not connect J8/J9 to the M/B on/off switch ifyou don’t want your PC to be started automatically. 1) Ignition=OFF. Nothing happens. FT-PR150B-ITPS is waiting for ignition signals. 2) Ignition=ON. FT-PR150B-ITPS waits for 2-3 seconds then turns on the 5Vsb rail. After another second FT-PR150B-ITPS sends an “ON” signal to the motherboard via the 2 wires connected to the motherboard’s ON/OFF pins. The motherboard will turn ON and your system should start booting. 3) Ignition=ON during driving. Your computer will remain ON. 4) Ignition=OFF. FT-PR150B-ITPS waits for “OFFDELAY” in seconds (see jumper chart on Page 2) and then it turns the motherboard OFF by sending a signal to the motherboard’s ON/OFF switch. Your computer should turn off gracefully (shutdown procedure). During this time, power will still be available for your PC to Model： FTITPS50B- Revision： A0 Page： 第 6 页 共 9 页 FT-PR150B-ITPS perform shutdown. 5) 5VSB will still be provided for another “HARDOFF” seconds (see jumper chart). In the event where the shutdown process is longer than “OFFDELAY” (windows gets frozen, etc), power will be shut down hard, turning off all power rails. If “HARDOFF” is set to ‘NEVER”, the PSU will always provide 5VSB, therefore the PC can also be used in the SLEEP mode. During the HARDOFF procedure, the battery levels will be constantly monitored to prevent deep discharge situations. 6) FT-PR150B-ITPS will go to step 1, if ignition is tuned ON again. 3.0 Troubleshooting a) a) Motherboard is not turning ON. FT-PR150B-ITPS User Guide Page 3 Check input cables. Measure voltage on the un-switched 12V. You should get about 12V. Measure the un-switched pin(red) while turning the car ON/OFF. You should see 12V (car on) or 0V (car off).. b) Motherboard is not turning ON (cont) . Check your output cables. Ensure total system power consumption does not exceed the FT-PR150B-ITPS specifications. Motherboard is not turning ON (cont).
