product manual:
ITPS-121208 is a computer power supply designed for single-supply operation. It has the function of ITPS follow-up and power-off. It only works 3 seconds after the vehicle is fired, and can automatically send the switch signal to the motherboard to realize the automatic computer. Boot up. After the vehicle is turned off, the computer and the power supply can be turned off according to the set continuous time, and the low-speed repeat mode can be entered. There is no need to worry about using the battery of the car battery, and the car cannot be fired. When the vehicle is abnormally extinguished and needs to be re-ignited (within 5 seconds), the computer will not restart or shut down.
ITPS-121208 is a high-efficiency automatic buck-boost voltage regulator module, which uses LTC3780 of American Linear Corporation as the main control chip. The input voltage can be both higher than the output voltage and the output voltage can be reduced, while the output voltage maintains a stable invariant. Set the output to 12V, then the output voltage will be constant at 12V when the input voltage changes between 5 and 32V.
Features:
Wide input voltage range: 5 ~ 32V
Output voltage: 2-24V continuously adjustable, default delivery 12V
Maximum output current: 10A (input 14V, output 12V)
Continuous output power: 120W
Input current limit: 15A (pluggable mini car fuse)
Advanced synchronous rectification technology with up to 98% conversion efficiency
Working frequency: 250KHz
An input surge absorbing circuit is specially designed for the vehicle environment.
Input and output terminal block with lock, suitable for vehicle vibration environment, will not fall off after long-term use
Full solid-state filter capacitor, high temperature resistance, stable, low output ripple
Output overcurrent, short circuit protection, the output terminal is not afraid even if short circuit, the circuit will automatically protect
Intelligent ACC switch control
Intelligent battery voltage monitoring
8 selectable delay modes
Input undervoltage protection, automatically turn off the output when the battery voltage is lower than 12V after ACC is powered off
No input reverse connection protection, input and output connection will be burned
Soft start function to ensure no overshoot voltage during power-on
