1Pcs 75W 5A Adjustable DC-DC Step-down Charge Module LED Driver with Voltmeter

NOTE : With cooling fin and copper cylinde. The step-down module when leaving the factory, the default output voltage at around 20 V. Module performance and features: With the power indicator light With voltmeter display and voltmeter can self calibration. Adopted more advanced microprocessor , voltage meter errorﾱ0.05V, measuring range 0 ~ 40 V. (note: to ensure the voltage meter accuracy, please make sure that the input voltage is above 4.5 V) Light touch button can switch measure input or output voltage, and a light show which way are measuring voltage, and save the settings Voltage meter can be closed, when don't need can touch the left side of the button can easily implement. With terminal blocks, no soldering iron can also ease to use, and keep welding line connection point. Input voltage is 4V to 38V. (input voltage must be higher than the output voltage of 1.5V ) Output voltage adjustable range 1.25 V ~ 35 V continuously adjustable. (the input voltage must be higher than the output voltage of 1.5 V) Output current can reach 5 A, suggest to use in 4.5 A Power output up to 75 w High conversion efficiency, up to 96% (efficiency is related to the input and output voltage, current and pressure difference) Load regulation S (I) ? 0.8% , voltage regulation S (u) ? 0.8% Have overheating protection and short circuit protection function Size : 60mm*37mm*18mm Weight : 28 g Packing List: 1Pcs 5A 75W Adjustable Power DC-DC Step-down Charge Module
