1. DC-DC 400W High-Power Step Down Buck Converter DC 10V-60V Constant Voltage Constant Current Adjustable
DC-DC 400W High-Power Step Down Buck Converter DC 10V-60V Constant Voltage Constant Current Adjustable 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).Product
model: SZ-BK061 2 Module
name: 400W step-down constant voltage constant current Module
nature: non isolated buck module Input
voltage: 10.5-60V.Output 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*0.8 (for example, the input is 40V, 40V*0.8 = 32V, the maximum output voltage is 32V, which will actually be higher to about 34V.35)Output 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 ~ 85â (heat dissipation shall be strengthene
