Item Type:Power Supply ModuleModel:WD5020Input Voltage:7~50VOutput Voltage:0~36V Continuous Adjustable(Can only be used as a step down module, the input must be greater than the output 1V or more)Output Current:Adjustable,20A Maximum(It is recommended to use it in 15A. It can naturally dissipate heat at 10A or below 140W. If it exceeds, please strengthen the heat dissipation! Constant current requires output voltage of 2V or more to adjust. Current regulation can only work under constant current state.)Output Power: Up to 300W (recommended to use within 250W, please reduce power when using large differential pressure)Working Temperature: -20~+75 ℃ (pay attention to the power tube temperature when using, please strengthen the heat dissipation)Working Frequency: 300KHzConversion efficiency: up to 95%Short Circuit Protection: Yes, constant current value currently set by constant currentInput Reverse Connection Protection: YesOutput Backflow: No, please add a diode for charging! Wiring Method: Terminal block or soldering terminal, VIN is input, VOUT is outputSize:100 x 60 x 48mm / 2、Step down voltage adjustable, can be used as battery charger, constant current LED driver module. 3.94 x 4、With short circuit protection and input reverse polarity protection. 2.36 x 1 x Module 1 x Module
