Ziqqucu | Adjustable Step Down Voltage Regulator Module 500W CC CV DC 12-95V to 1.5-90V Constant Current Buck Converter

Features:1.The module adopts a step rectification scheme, with extremely high efficiency, with a maximum efficiency of 96%2.The output voltage and current are continuously adjustable3.The maximum input voltage can reach 95V, and the maximum output voltage is 90V4.Input anti reverse connection, positive and negative reverse connection without burning5.There is a soft start switchParameters:Module name: 500w step-down constant voltage constant current adjustable power moduleModule nature: Non isolated step-down moduleInput voltage: 12-95VOutput voltage range: 1.5-90V (can only reduce voltage, cannot increase voltage, output voltage can only be lower than input voltage)Input output pressure difference: 2VOutput constant current: 0.3-18A (continuously adjustable)Output rated current: 15ARated output power: 400wInput overvoltage protection: None (overpressure prohibited)Working temperature: -10~+65 degrees CelsiusWorking frequency: 120KHzConversion efficiency: up to 96% (efficiency is related to input and output voltage, current, and voltage difference)Short circuit protection: Yes (constant current protection)Input reverse protection: Yes (MOS transistor reverse connection)Output anti backflow: None (charging the battery, connecting the output to an inductive load, such as adding anti backflow diodes when connecting to the motor)Precautions:1. If the input voltage exceeds 36V, first turn the ON/OFF switch to OFF, connect the wire, 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. Under natural heat dissipation, the power should not exceed 400W and the current should not exceed 15A. There is a power limit. If the output voltage is high and the input output voltage difference is large, please reduce the current and use it4. If the current exceeds 15A and the power exceeds 400W, please add a fan for heat dissipationVoltage and current adjustment method: (using a tool multimeter and a flat screwdriver)Voltage regulation: turn the blue Potentiometer on the power panel according to the voltage you need, and turn the voltage up clockwise and down counterclockwise;Output current regulation: turn the multimeter or Ammeter to 20A or 10A current gear, adjust the power supply voltage to 5V, turn the constant current Potentiometer counterclockwise for about 10 turns, adjust the current to the minimum, use the multimeter for short circuit output, and then adjust the Potentiometer clockwise to adjust the current to the required current value;The current detection of the module is a low-end detection. Please do not directly short circuit the input negative pole and output negative pole with wires, as the short circuit negative pole power supply may not have constant current, resulting in damage to the power supply and electrical equipment that requires constant current.The module is a step-down power supply that can only reduce voltage but cannot increase it. The input voltage must be higher than the output voltage.Package include:Module X1
