DC-DC 400W 15A 10.5-60V to 10-60V Voltage high power step-down constant voltage constant current adjustable power module
Main features of power supply module:
*10-60v wide input voltage, suitable for most power supplies on the market as the input source.
*Output constant voltage and constant current, continuously adjustable voltage and current. Can meet most of the electrical equipment.
*High output power, good ventilation and natural heat dissipation can achieve 280W/12A (note that there are output power and output current limits).
*The module adopts a step rectification scheme, which has extremely high efficiency. The output voltage is above 10V and the efficiency is as high as 92% -96% .
*There is a constant current indicator when charging the battery. The charging status is clear at a glance.
*The input has a 15A fuse, and the positive and negative poles of the input will not damage the power supply (the fuse will be burned, and the fuse needs to be replaced)
Module parameters
Product model: SZ-BK0612
Module name: 400w step-down constant voltage and constant current
Module nature: non-isolated step-down module (BUCK)
Input voltage: 10.5-60V
Output voltage range: 0-45V (must meet the step-down condition, IN input is multiplied by 0.8)
Minimum output voltage: 0V ( 1V)
The highest output voltage: approximately equal to the input *0.8 (for example, the input is 40V, 40V*0.8=32V, the highest output voltage is 32V, which will actually be a little higher and reach about 34V.35)
Output constant current: 0.2-15A (continuously adjustable, heat dissipation should be strengthened if it exceeds 12A)
Maximum output power: 400W (a fan needs to be added for forced cooling of the heat sink and magnetic ring)
Continuous maximum working power: 280W (under ventilated environment)
Continuous maximum working current: 12A (under ventilated environment)
Input under-voltage protection: Yes, (input is lower than 10.5V to turn off the output, there is an error of about 0.5V)
Input overvoltage protection: none (overvoltage is prohibited)
Working temperature: -10~ 85 degrees (enhance heat dissipation when it exceeds 65 degrees)
Working frequency: 100KHz
Conversion efficiency: up to 97% (efficiency is related to input, output voltage, current, and pressure difference)
Short circuit protection: Yes (constant current protection)
Input reverse connection protection: Yes (please be careful when short-circuiting the input and the input reverse connection will burn the input fuse)
Output anti-recharge: none (to charge the battery, output connect inductive load, for example, anti-reverse diode must be added to the motor)
Work indicator: Yes (blue LED light)
Constant current indicator light: Yes (the CC indicator red light on the small board lights up when the constant current is working, there is no current output, and the light does not light up when the voltage is constant)
Connection method: Comes with welding-free 25A terminal block
Module size: length 60 width 60mm high 45mm
Net weight: 170 grams. 180 grams with packaging.
Packing method: independent carton packaging.
Wiring: "Input/IN" is input. "Output/OUT" is output (marked in Chinese)
 
Precautions:
*It is strictly forbidden to connect the input and output positive and negative poles (the fuse will be burnt if the input is reversed, and the control board will be damaged if the output is reversed. The damage of the small board cannot be repaired and can only be replaced.
*The control panel is a little rainproof glue, if it is damaged, it can only be replaced. Mind shooting carefully
*When charging the battery, when the output is connected to an inductive load, the output should be equipped with an anti-reflow diode
 
Voltage and current adjustment method: (use tool multimeter, flat-blade screwdriver)
Voltage adjustment: Turn the "CV" blue potentiometer on the power supply board according to the voltage you need to increase the voltage clockwise and decrease it counterclockwise
Output current adjustment: Set the multimeter to the 20A or 10A current position, adjust the power supply voltage to 5V, turn the constant current potentiometer "CC" 20 times counterclockwise, adjust the current to the minimum, use the multimeter to short-circuit the output, and then adjust clockwise The "CC" potentiometer adjusts the current to the required current value. (Note: When the constant current potentiometer "CC" rotates 20 times counterclockwise, the power supply may have no output voltage. At this time, the current is adjusted to 0A. No need Regardless of him, turn the current clockwise to increase the output and there will be output.)
The module's current detection is low-end detection. Please do not short-circuit the negative input and output negative directly with a wire. Short-circuit the negative power supply without constant current, which will damage the power supply and electrical equipment that requires constant current.
The module is a step-down power supply that can only step down but not up. The input voltage must be higher than the output voltage.
