 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
