Specifications:Model: SZ-BK0612Module nature: non isolated buck module(Buck)Input voltage: 10.5-60VOutput voltage range: 0-45V (must meet the step-down conditions, in input multiplied by 0.8)Minimum output voltage: 0V (+1V)Maximum output voltage: about equal input*0.8Output constant current: 0.2-15A (continuously adjustable, heat dissipation shall be strengthened if it exceeds 12A)Maximum output power: 400W (it is necessary to add a fan to forcibly heat the heat sink and magnetic ring)Continuous maximum working power: 280W (in ventilated environment)Continuous maximum working current: 12A (in ventilated environment)Input undervoltage protection: Yes, (the input is lower than 10.5V, the output is closed, and there is an error of about 0.5V)Input overvoltage protection: none (overpressure prohibited)Working temperature: -10 ~ 85 (heat dissipation shall be strengthened when it exceeds 65)Operating frequency: 100kHzConversion 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 (in case of short circuit, input reverse connection shall be cautious, which will burn the input fuse)Output anti backflow: none (when charging the battery, the output is connected to inductive load, for example, the anti backflow diode must be added to the motor)Work indicator light: blue LED lightConstant current indicator: Yes Wiring mode: self equipped welding free 25A wiring terminalSize: 60*60*45mm It is a DC-DC 400W High Power Supply Step Down Module CVCC 10.5V-60V to 0-45V Buck Voltage Converter. 10-60V wide input voltage, suitable for most power supplies on the market as input source. 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) SHOP WITH CONFIDENCE: To provide you with the highest quality service, If you have any question, please feel free to contact us.We will provide after-sales service until you are satisfied.
