22A 1400W DC 6-75V Stabilized Voltage Power Supply Step-Down Module CNC Adjustable Voltage Regulators

Product description 1. LCD display board sinking gold process, put an end to oxidized poor contact, put an end to long-time use of incomplete display 2. Independent silicone key to set the voltage or current, a key to enter, a key to exit, fast and concise, refuse to cumbersome 3.1. 8 inch large color screen display content is more rich and intuitive, the operation of the setup is more simple 4. Individual motherboard use flexible, support current stepless adjustment, voltage stepless adjustment 5. PCB immersion gold process, to prevent key failure after long-term use, to protect the circuit board pad is not oxidized, improve PCB conductivity, reduce line impedance and contact resistance

1. No AC input, not to mention the 220V utility
2. Input voltage up to 75V, can not be over-voltage input or reverse positive and negative poles
3. The output can not be completely guaranteed to prevent backflow, connect the battery to ensure that the output voltage of the power supply module is always higher than the battery voltage, or in the output anode series diode single conduction, to prevent the battery voltage backflow burned power supply
4. When connecting the battery to the output terminal, please pay attention to the positive and negative poles not to be connected to the opposite side.
5. The product is a step-down module, the maximum output voltage = input voltage * 0.95 -1V See More
