DC-DC 400W High Power Buck Converter DC 10V-60V Constant Voltage Constant Current Adjustable Step-Down Power Module SZ-BK6012 QS-BK6012-400W

Feature:

• *10-60V wide input voltage, suitable for most power supplies on the market as input sources.
• * Output constant voltage and constant current, and the voltage and constant current are continuously adjustable. It can satisfy most electrical equipment.
• * High output power, good ventilation, and natural heat dissipation can reach 280W/12A (pay attention to the output power and output current limit).
• *The module adopts a step-by-step rectification scheme with high efficiency. The output voltage is greater than 10V, and the efficiency is greater than 92%-96%.
• *There is a constant current indication when the battery is charging. The charging status is clear at a glance.
• *The input has a 15A fuse, and the positive and negative poles of the input are reversed, which will not damage the power supply (the fuse will burn, and the fuse needs to be replaced).

Product parameters:

• Module name: 400W step-down constant voltage constant current
• Module nature: non-isolated step-down module
• Input voltage: 10.5-60V
• Output voltage range: 0-45V (must meet the step-down condition, multiply the input by 0.8)
• Minimum output voltage: 0V (+1V)
• Maximum output voltage: approximately equal to input*0.8 (for example, if the input is 40V, 40V*0.8=32V, the maximum output voltage is 32V, which will actually be as high as 34V.35)
• Output constant current: 0.2-15A (continuously adjustable, more than 12A need to strengthen heat dissipation)
• Maximum output power: 400W (need to add a fan to forcibly heat the heat sink and magnetic ring)
• Continuous maximum working power: 280W (in a ventilated environment)
• Continuous maximum working current: 12A (in a ventilated environment)
• Input under-voltage protection: yes, (the input is lower than 10.5V, the output is turned off, there is an error of about 0.5V)
• Input overvoltage protection: none (overvoltage prohibited)
• Working temperature: -10~+85℃ (over 65℃, heat dissipation needs to be strengthened)
• Working frequency: 100kHz
• Conversion efficiency: up to 97% (efficiency is related to input and output voltage, current and voltage difference)
• Short circuit protection: yes (constant current protection)
• Input reverse connection protection: yes (if a short circuit occurs, be careful with input reverse connection, it will burn the input fuse)
• Output anti-reverse current: no (when charging the battery, the output is connected to an inductive load, such as the motor must be equipped with an anti-reverse current diode)
• Work indicator: yes (blue LED light)
• Constant current indicator: Yes (the CC indicator on the small board is on red when the constant current is working, there is no current output, and the light is off when the constant voltage is working)
• Wiring method: self-matching solderless 25A terminal block
• Module size: length 60, width 60mm, height 45mm
• Packing: independent carton packaging.
• Net weight: 180g

• Gross weight: 210g
