Best Constant Power Output

ACEIRMC 3pcs 20A 300W CC CV Step Down Module Adjustable DC 6-40V to 1.2-36V Voltage Regulator Buck Converter Constant Current Power Supply Module

Aceirmc buck converter input voltage range is DC 6-40V, adjustable output voltage range is DC 1.2-36V, can be used to convert 24v to 12v 5v, adjustable output current range is 0-20A, max output power is 300W. The step down regulator can apply to constant output current..
With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. The efficiency can be up to 95%,(measured at 20A, converting 24V to 12V)..
Short Circuit Protection: Self-recovery(cannot short circuit for long time). Plus, when input and output is common grounded, no-load CV output constant voltage,CC output constant current.
Adopting 75V / 80A large current dual MOS tube designed step-down board, Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. Large current 30A connection screw terminals, more convenient to install.
Application: DIY stabilized voltage supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fans, photovoltaic energy, motor, etc....

...ital LCD display on which shows both voltage and current value simultaneously. Which is easy to read and can help the user easily monitor the output voltage, then largely enjoy their DIY work..
General Application --- This voltage step up converter can be used as ordinary step-up module with over-current protection, constant current LED driver module.
Features --- Constant current/voltage mode.
Input reverse connection protection. You can find the PDF Instructions on this page -- Product information -- Product guides and documents -- User Manual [PDF]..
NOTE --- 1). Constant current adjustable means that CC mode only works when the actual load output current is greater than the setting one, otherwise it will work in a constant voltage state, not the current is adjusted to 2A, then it will become 2A for any load being connected. And if the CC value to be adjusted is small, adjust “ADJ-I” counterclockwise a few more times to change. 2). The case is packaged disassembly to avoid damage during transit. It needs to be manually installed..
