Aideepen | 500W Step-Down Power Module Constant Voltage Constant Current DC 12-95V to 1.5-90V 18A High-Power Adjustable Step-down converter

Product features:1. The module adopts step rectification scheme with high efficiency, the highest efficiency is as high as 96%2. The output voltage and current are continuously adjustable3. Input voltage up to 95V, output voltage up to 90V4. There is input anti-reverse connection, positive and negative connection does not burn5. A soft start switch is availableModule parameters:Module name :500w step-down constant voltage and constant current adjustable power moduleModule nature: non-isolated buck moduleInput voltage :12-95VOutput voltage range :1.5-90V(only buck, not boost, output voltage can only be low to input voltage)Input/output pressure difference :2VOutput constant current :0.3--18A(continuously adjustable,)Output rated current :15AOutput rated power :400wInput overvoltage protection: None (no overvoltage)Operating temperature :-10~+65 degreesOperating frequency :120KHzConversion efficiency: up to 96% (efficiency is related to input, output voltage, current, pressure difference)Short circuit protection: Yes (constant current protection)Input reverse protection: Yes (MOS tube reverse)Output anti-backfilling: none (to charge the battery, the output is connected to inductive load, such as the motor must add anti-backfilling diode)Note:1. If the input voltage exceeds 36V, first turn the ON/OF switch to OF, connect the line and then turn the switch to ON(to prevent ignition during wiring)2. This power supply is a step-down power supply, and the output voltage can only be lower than the input voltage3. In the case of natural heat dissipation, the power does not exceed 400W, the current does not exceed 15A, and the power is limited. If the output voltage is high and the input and output pressure difference is large, please use the drop current4. If the current exceeds 15A and the power exceeds 400W, add a fan for heat dissipationVoltage and current adjustment method: (Use multimeter, flat-head screwdriver)Voltage regulation: Rotate the blue potentiometer on the power supply board according to the required voltage, turn the voltage up clockwise and turn it down anticlockwise;Output current adjustment: multimeter or ammeter to 20A or 10A current gear, the power supply voltage to 5V, constant current potentiometer counterclockwise about 10 turns, the current to the minimum short-circuit output with the multimeter, and then clockwise adjust the potentiometer current to the required current value;The current detection of the module is low-end. Do not short-circuit the input negative electrode and the output negative electrode directly with a wire. This will short-circuit the negative power supply and cause damage to the power supply and the electrical equipment requiring constant current.Module for step-down power supply can only step-down can not rise, the input voltage must be higher than the output voltage.Shipping list:Step-down converter *1
