2A Buck Step-down Power Converter Module DC 4 ~ 40 to 1.3-37V with LED Voltmeter

This is LM2596 2A Buck Step-down Power Converter Module DC 4 ~ 40 to 1.3 ~ 37V, it comes with a built-in voltmeter display and uses an advanced microcontroller.

Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 ~ 40V and an adjustable output range of 1.3 ~ 37V.

Notes: Maximum current is dependent on input and output voltages, ambient temperature and cooling. To achieve maximum ratings an external heatsink may be required. Maximum LM2596 operating temperature must not exceed 125°C otherwise permanent thermal damage can occur.
Features :
Input reverse polarity protection
Built-in output short protection function
The built-in thermal shutdown function
Press the right key to let the display show the input or output voltage. when the right “OUT” led light, it shows output, the left “IN” led show input.
Power-off memory function, show that road after power voltage values measured for the last time
Press the touch button for 3 seconds to turn off the LED display, touch the button again to turn on the LED display
The band terminals, no iron can also be easy to use, and retention wire connection point

DC-DC Step-Up Boost Converter 10-32V to 12-35V 6A Adjustable Power Supply Module

This versatile DC-DC boost power supply/converter module steps up any input voltage from 10V to 32V to any output voltage from 12V to 35V at up to 150W output power and 6A current.

This 150W DC-DC Boost Converter 10-32V to 12-35V 6A Step-Up Adjustable Power Supply is well into the heavy-duty end of the spectrum @ 150W; as you can tell by the huge toroidal inductor and dual heatsinks.

It is especially useful for automotive 12V applications, where standard 12V battery power can be boosted to 19V for use as a laptop computer power supply, or to 18V or 24V for other applications requiring higher voltages.

Please note there is no reverse polarity protection. A series diode is recommended. For high loads this might not be an option; so be cautious of the input polarity or you might fry the module!

Specifications and Features :-

Input voltage :10-32V
Output voltage: 12-35V (adjustable)
Output Current: 10A (MAX)
Input Current: 16A (MAX) (Please enhance heat dissipation if more than 10A)
The non-isolated step-up power conversion module
Onboard LED illuminates when the voltage is applied to the module
Equips Multi-turn Potentiometer.
Easy to drive 65W 90W dual-core notebook.
The output voltage is continuously adjustable on OUT+ and OUT- screw terminals (Output voltage must be greater than input voltage)

Applications:-

DIY adjustable output vehicle power supply. Provide 12V input, the output voltage can be continuously adjusted from 14V to 35V (output voltage cannot be lower than the input voltage).
Universal car laptop power supply. Provide 12V input, the output voltage is adjustable to your notebook to work. Can easily drive dual-core or quad-core notebooks at 19V and up to 6A output current.
Boost Charger, to convert your car’s 12V power to greater than 12V, such as 18V or 24V
Power supply for your electronic devices, as long as the voltage is adjusted to the voltage and does not exceed the module’s rated current.

Note:-

Set the output voltage to the desired level using a voltmeter before connecting it to your equipment or load.
Short circuit protection: None, please use caution to protect the module from overcurrent
Input reverse polarity protection: None, please use a diode in series with the input to protect against input reverse polarity
