This is a smart car DC ATX power supply with ITPS function, which can control the motherboard on and off according to the car's ignition status, and can provide a maximum power output of 180W. after the car is turned off, X5-ATX will send a shutdown signal to the motherboard to shut down the computer, and then continue to wait for 90 seconds or 600 seconds (you can use the jumper cap to select the length of the delay), then +5VSB (standby voltage) Turn off to protect your car battery from being drained by a traditional ATX power supply when the car is turned off for a long time. X5-ATX will continuously detect the voltage of the car battery during operation. If the battery voltage continues to be lower than 11V for more than 60 seconds, X5-ATX will shut down all voltage outputs and will not resume voltage output until the car battery voltage exceeds 11V. Engine cold start, overvoltage, undervoltage and overcurrent protection. X5-ATX can work with an input voltage of 6-25V, which means it can work normally when the battery voltage to 6V instantly when the engine is cold started. In addition, the input end of X5-ATX is equipped with a tube to resist instant overvoltage, and a 15A/40V fuse for overcurrent protection. Therefore, X5-ATX can be used to build safe 12V battery-powered computer systems. Note:Due to different production batches, the components on the power board may be different from the pictures, but the functions are the same and do not affect use. With no fan design, absolute silence, support battery input, car computer, home entertainment computer HTPC, mini computer and industrial control host, etc. Input voltage:DC 6-25V Product model:x5-atx-180 Interface specification:20pin socket special specification Conversion efficiency:95% Output power:rated 150W, 180W Overload protection:overvoltage protection Colour:Blue Material:PCB+electronic components Package Contents: 1 * power board 1 set * cables 3 * terminals (Terminal colors are random, no specification is accepted) Only the above package content, other products are not included.
