Brand N/A Model 03100410 Quantity 1 Color Green Material Glass fiber + Semiconductor Specification 1 Input voltage 8~40V output can be adjusted between 4~32V. 2 On-board heat sink rated output current 3A power up to 90W or so the efficiency up to 95% or more. 3 As is the step-down DC-DC circuit the input voltage needs to be higher than output voltage 4V or more in order to ensure the stability of the output voltage. (Optimum operating voltage is higher than the output input 5~15V). 4 With short circuit overheating protection output short circuit is not afraid even if the circuit will automatically protect; Empty load the static power consumption is only about 10mA Features Buck module Application Buck module English Manual/Spec Yes Other PCB board with high-quality epoxy fiberglass board selected high quality components ensure that the circuit is safer and secure work. Potentiometers are used to ensure 3296 Precision Potentiometer adjustable output resolution up to 10mV high-capacity filter capacitors to ensure low ripple the output is more stable the output voltage samples collected directly from the guarantee lower load regulation. Onboard four 3.5MM convenient positioning hole module mounting. Packing List 1 x DC to DC step-down module (output 4~32V / 3A)
