Comparison of buck and boost of solar street light controller
What is the difference between the step-down type and the step-up type of solar street light controller:
These two controllers belong to the combination of solar controller and LED light source drive. Both controllers are suitable for the case where the LED light source is not driven. The boost type uses a DC~DC circuit to convert the low voltage 12V or 24V, up to 40~50V, suitable for modules with about 10 strings of LED lamp beads. This model is characterized by high voltage and low current; the step-down type is to reduce the voltage through a DC~DC circuit, and 12V is reduced to 10V Around, this model is characterized by low voltage and large current.
The quality of the step-down and step-up controllers varies from manufacturer to manufacturer. The choice of controller is to find a professional manufacturer of large-scale solar lamps.
