DC/DC Step-Down Regulator Module -400W, 15A

Key features of DC/DC Step-Down Regulator Module - 400W, 15A

• Output constant voltage and current. Voltage and current continuously adjustable. It can meet most electric equipment. High output power, good ventilation and natural heat dissipation can reach 280W/12A (pay attention to the limitation of output power and output current).
• The module adopts step rectification scheme, with high efficiency. The output voltage is more than 10V, and the efficiency is more than 92%-96%. There is a constant current indication when charging the battery. The charging state is clear at a glance.
• The input has a 15A fuse, and the input positive and negative poles are connected reversely, which will not damage the power supply. (the fuse will burn, and the fuse needs to be replaced)

How to use DC/DC Step-Down Regulator Module - 400W, 15A

VOLTAGE AND CURRENT REGULATION METHOD(Use A Tool Multimeter And A Slotted Screwdriver)

• Voltage regulation: turn the "CV" blue potentiometer on the power panel according to the required voltage, and turn the voltage up clockwise and down counterclockwise.
• Output current regulation: turn the multimeter to the 20A or 10A current gear, adjust the power supply voltage to 5V, turn the constant current potentiometer "CC" counterclockwise for 20 turns, adjust the current to the minimum, use the multimeter for short circuit output, and then adjust the "CC" potentiometer clockwise to adjust the current to the required current value, (Note: When the constant current potentiometer "CC" is turned counterclockwise for 20 turns, the power supply may have no output voltage. At this time, the current is adjusted to OA. Never mind, the current will be output when it is turned up clockwise.)
• The current detection of the module is low end detection. Please do not directly short circuit the input negative pole and the output negative pole with a wire. The short circuit negative pole power supply is not constant current, causing damage to the power supply and electrical equipment requiring constant current.We Are The Distributor Of TZT Brand In Hong Kong, China.
  The module is a step-down power supply, which can only be step-down but can not be raised. The input voltage must be higher than the output voltage.
