Features: This is a non-isolation DC regulated power converter module with long service life. High power and stable output, it converts 4-32VDC to 1.2-32VDC. High quality components ensures high conversion efficiency, up to 98%. Designed with terminal blocks for easy and convenient wiring. It has constant voltage and constant current function, and supports short circuit protection. Specification: Type: Non-isolated step-down module (BUCK) synchronous rectification Input Voltage: 4-32V (limitation 36V) Output Voltage: 1.2V - 32V continuously adjustable Minimum Difference of Input/Output Voltage: 1V (input voltage should be higher than output voltage) Output Current: 0-10A (within 6A for long-term use of natural cooling, temperature should not exceed 60. Please reduce rated values if ambient temperature is high) Output Constant Current: 0.3-10A (adjustable) Operating Temperature: -40 to +85 Frequency: 150KHz Maximum Conversion Efficiency: 98% (Efficiency is related to input/output voltage, current and voltage difference) Short Circuit Protection: Support (limit current is constant current ) Reverse Input Protection: No, please connect to a diode in series at input if needed Output Flow-back Protection: No, please connect to a diode in series at input if needed Weight: 30g / 1.1oz (approx.) Package list: 1 * Module Voltage and Current Setting: 1, Set the output voltage:According to the float charging voltage value of the charged battery, or the voltage value of LEDs in series, regulating constant-voltage potentiometer (CV), to set output voltage to the required voltage. (setting when no load) 2, Set the constant current value:rotate CC potentiometer counterclockwise about 20 circles, then connect load with the ammeter, set CC potentiometer to required current value. Do not use the method of short circuit to directly regulate the constant current value. Note: When setting constant current, the voltage should be higher than 1.2V, otherwise constant current function will not work.
