Description

DC-DC converter 1.5A – 3-35V – step-down – LM317

Freely adjustable inverter from 4.2V to 40V – to adjustable voltage from 1.2V to 37V. This device allows for a safe, stable power supply for electronics such as FPV cameras. LM317 circuit used, which is an adjustable positive voltage stabilizer circuit.

(NOTE potentiometers have a wide scale of approx. 50 turns )

Comments

• The device regulates voltage by lowering (not raising) the voltage. The supply voltage must be greater than the consumer voltage.
• Incorrect connection of power supply polarity causes damage to inverter
• This device is for experienced do-it-yourselfers, basic electronics knowledge and soldering skills are required. The company is not responsible for damages resulting from lack of soldering skills or poorly made electrical installations.
• Check the output voltage and adjust with the proper potentiometer and only then connect the receiving device
