مبدل DC-DC کاهنده برای تبدیل 4.5-30 ولت به 0.8-28 ولت 12A

Module Properties: non-isolated step-down module
Input voltage : 4.5-30V
Output voltage: 0.8-28V (adjustable) output must be lower 2V than input.
Output Current: 0 - 12A (MAX)
Input Current: 12A (MAX) (Please enhance heat dissipation if more than 10A)
Output power: natural cooling 100W , enhance heat dissipation 200W (MAX)
Conversion efficiency: 95% 
Operating Temperature: Industrial (-40°c to +85°c) (ambient temperature exceeds 40°c, lower power use, or to enhance heat dissipation)
Short circuit protection: None (Please Install fuses and protection circuits at Input port.)
Input Reverse Polarity Protection: None (Please Series diode at the input port.)
( recommendation：working under 8A would be better. if want it work with 10-12A for long time,please add the fan for cooling )
