DC-DC adjustable step-down power Supply module ,5A Large current
Areas of application:
DIY mobile power supply, car power, communications equipment power supply, etc.
output current: peak 5A (more than 3.5A work need to strengthen The cooling)
The step-down module can easily reach 4 a, 50 w, add heat sink can reach 75 w, under the condition of extremely high price!!!!!Modules window: 5 a high-power high efficiency low rippleModule performance and features:Module properties: the isolation step-down module (BUCK)4-38 v input voltage: (please try not to exceed 38 v input)Output voltage: 1.25-32 v continuous adjustableOutput current: 0-5 A, it is recommended to use in 4.5 A.Output power: it is recommended that use within the 75 w, more than 50 w please add heat sink.Working temperature: - 40 ~ + 85 degreesWorking frequency: 180 KHZConversion efficiency: up to 96% (efficiency and the input, output voltage, current and pressure difference)Load regulation: S (I) 0.8% or lessVoltage regulation: S (u) of 0.8% or lessPower light: yesShort circuit protection: (limit current 8 a)Overtemperature protection: (overtemperature after automatic shut off output)Input reverse connect protection: no, (such as the need to please in the input string into the high current diode)Installation method: 2 3 mm wire the self-containedConnection mode: welding, V - IN for the input, V - OUT for the outputModule size: 23 mm, 18 mm long 54 mm wide
