300W 12A Adjustable DC-DC CC CV Converter Step-down Power Supply Module

Features: *Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging). *Made from a dedicated for IC and high- for precision current sensing resistor, proving a more stable constant current, (when 20° to 100° constant current 1A, temperature drift less than 1%). Particularly suitable for driver. *High output current, the max output current can reach 12A. *Four high frequency capacitance, can lower output ripple, enhance the work stabilization. Specifications: Module Properties: non-isolated step-down constant current, constant voltage module (CC ) charging module Input voltage: DC 7-32V Output voltage:DC 0.8-28V continuously adjustable Output Current: 9A 12A (when power tube\'s temperature exceeds 65 degrees, please add cooling fan) Constant current range: 0.2-12A ( adjustable ) Turn lamp current: constant current value * ( 0.1 ) , turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A). Lowest pressure: 1V Output Power: Maximum power is about 300W Conversion efficiency: up to about 95% Operating frequency: 300KHZ Output ripple: 20M bandwidth Input 24V Output 12V 5A ripple around 50mV (Excluding noise) Output short circuit for protection : Yes, constant current Input Reverse Polarity for Protection: None Output prevent backflow: None Wiring: Terminal No-load current: Typical 20mA (24V switch 12V) Load regulation: ± 1% ( constant ) Voltage regulation: ± 1% for Dynamic for response speed: 5% 200uS Potentiometer adjustment direction: clockwise (increase) , counterclockwise (decrease). the potentiometer() closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC) Operating temperature: Industrial grade (-40 °c to +85 °c) ( please note the actual use of the power tube temperature , high temperature heat strengthened please ) Indicator: dual color indicator, charging indicator light is red, the green light means fully charged ( No load is green ) Package Contents: 1 Pcs Converter Module Note: 1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2. Please allow slight manual measurement deviation for the data.
