Ieik® 300w 8A Constant Current/voltage Dc Buck Converter 7-40v to 1.2-35v Led Driver Charger Module

Description

Module parameters: Module Properties: non-isolated step-down constant current , constant voltage module (CC CV) charging module Input voltage : DC 7-40V Output voltage :DC 1.2-35V continuously adjustable Output Current: 8A ( when power tube's temperature exceeds 65 degrees, please add cooling fan ) Constant current range :0.2-8A ( 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: 300W, Maximum Conversion efficiency : up to about 95% Operating frequency : 300KHZ Output ripple : 20M bandwidth Input 24V Output 12V 5A ripple around 50mV ( excluding noise ) Operating temperature : Industrial grade (-40 °c to +85 °c) ( please note the actual use of the power tube temperature , high temperature heat strengthened please ) No-load current : Typical 20mA (24V switch 12V) Load regulation : ± 1% ( constant ) Voltage regulation : ± 1% Dynamic response speed : 5% 200uS Potentiometer adjustment direction : clockwise ( increase ) , counterclockwise ( decrease ) . the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC) Indicator : dual color indicator , charging indicator light is red , the green light means fully charged ( No load is green ) Output short circuit protection : Yes , constant current Dimensions : 65 * 47 * 23.5 mm Package include: 1x IEIK® DC Step-down Power Converter
