4A DC-DC Step-down Adjustable Constant Voltage Module

The 4A DC-DC Step-down Adjustable Constant Voltage Module is a power supply module that efficiently converts a higher input DC voltage to a lower output DC voltage, while providing constant voltage regulation. This type of module is commonly used in electronic projects, battery charging, and powering devices that require a stable voltage output.

Applications:

• High-power LED driver.
• Lithium battery(or lead accumulator) charge.
• Vehicle-mounted power supply.
• Low voltage system power supply.
• 6V, 12V, 14V, 24V battery charge.
• On-board laptop power supply.
• Regulated power supply.
• Low voltage power supply system.

Note: If the module temperature exceeds 65ºC, please add a cooling fan,  (It be used at room temperature without a fan)

Features:

• Scope: High-power LED constant current driver, rechargeable lithium batteries 4V, 6V, 12V, 14V, 24V battery charging; nickel-cadmium nickel-metal hydride batteries (battery) charging, solar panels, wind generators.
• Operating temperature: -40 ℃ to + 85 ℃ (please note the actual use of the power tube temperature, the temperature is too high, please enhance heat dissipation).
