DC Power Supply [car] buck buck DC power supply for the protection of life

This product is imported DC-DC step-down module, input reverse polarity protection circuit, output overvoltage protection circuit, input and output filter circuit combination. Dual battery power supply in series (24V) vehicle electrical system, as a buck to use. It has good accuracy and anti-jamming capability regulator output voltage ripple <100mV. Both very sensitive overcurrent protection, protection of the life of the power play a very crucial role. Accessibility Input Reverse Protection: Reverse input protection circuit is a diode in parallel to the input back-end implementation. When the input voltage is reversed, the rear end of the input diode reverse blocking characteristics, and thus play an input terminal voltage of reverse polarity protection. Output voltage protection: When DC-DC step-down module breakdown or other electrical faults, causing the output voltage is increased to 18 ± 0.5V, the output of the power supply output protection circuit and the load is disconnected. Output over-current protection: When the output current is straight up or overload, current limiting device can respond quickly and limits the output current level on the 5A ± 200mA. Work status indication: When the circuit malfunction, causing abnormal output, the light does not shine. Circuit is working properly, the indicator light.
