Module Convertisseur DC/DC step-up/down
Caractéristiques
Module name: 5A automatic constant voltage constant current step-up/step-down
Module Properties: non-isolated synchronous rectifier step-up/step-down module automatically
Input voltage :DC5-32V
Input Current: 8A (MAX) Peak 10A (can use in Long working hours when input Current:⇐ 6A)
Quiescent Current: 4mA (Operating Voltage Different,There will be errors)
Output voltage: DC1.25-20V continuously adjustable
Output Current: 5A (MAX) (it can be long time susing when natural cooling out put current ⇐3A) For higher output current, two modules can be used in parallel, such as the output to 6A, you can use two modules in parallel, the current of each module can be transferred to 3.5A.
Output current range :0.2-5A
Operating temperature: -40 to +85°C
Operating Frequency: 150KHz
Conversion efficiency: Up to 96% (efficiency and input and output voltage, current, voltage dropout related)
Current protection: yes
Short circuit protection: (enter the 10A fuse) double circuit protection, use more secure.
Over-temperature protection: Yes (over-temperature automatically reduces the output voltage)
Input Reverse Polarity Protection: None, (if required in the input string into diode)
Output anti-anti-irrigation: Yes, for charging plus blocking diode is not required.
Installation: four 3mm screws
Connection: welding output, (V-IN as an input, V-OUT is the output)
Module dimensions: length 60mm* width 40mm* height 30mm
Applications
This module can be applied to relatively large fluctuations in the input voltage, the output requirements are relatively stable area. Such as:
DIY a power supply, input 12V can, output can be 1.2-20V adjustable
the power for your electronic devices, can according to your system set output voltage value
as the Car power supply voltage for your laptop, PDA, or a variety of digital products supply
DIY a laptop mobile power supply: 12V coupled with high-capacity lithium battery pack
the solar panel regulator
to the battery, lithium battery charging
driving high-power LED lights.
Operating Description
regulating potentiometer CV
set CC potentiometer counterclockwise around 30 laps the output current is set to minimum, connect the LED, adjust CC to the desired current.
For battery charging, the battery is discharged, and then connected to the output, adjust to your desired current CC (for sure when Charging the battery completely discharged before being allowed to adjust, because the battery charge remaining in the charge current is smaller.)
Please do not use short way to transfer current, the circuit structure of this module can not be used the way short tune.
