【Auto Reverse Function】This cassette converter can automatically switch sides of tape while a conversion is underway. Compact Si....

lithium-ion switch to change charging modes between lead-acid and lithium batteries.
converter type: three-stage converter, two-stage converter.
voltage output: 13.2-14.6 vdc, 13.6-14.6 vdc.
standard safety features/protections: over current, over temperature, over voltage, reverse polarity, short circuit, cooling system.

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....
