LM2596 DC to DC Buck Step Down Power Module 4.2V-40V to 1.25V-37V DC-DC Converter with LED VoltMeter Display

Overview:

• With voltage meter display, voltage meter error of± 0.1V, the range of 0~40V. (note: to ensure that the voltage meter accuracy, please make sure that the input voltage is 4.2V or more).
• Low light touch button switch measurement input or output voltage, and a light show is voltage measurement which road, and keep the last set, even if the power switch on again.
• Voltmeter fine-tuning: hold down the button about 1-2s into fine-tuning mode, can remove button on the calibration at this time. (please do not use standby function, usually).
• Low voltage meter can be closed, long press button closure voltmeter (minimum power loss).
• Input voltage: 4.2 ~40v (input voltage must be higher than to the output voltage of more than 1v).
• Output voltage adjustable range 1.25V ~37V adjustable (input voltage must be higher than to the output voltage is more than 1V).
• Maximum output current can be as high as 3A, normal and stable-working current in 2A.
• Low the internal oscillation frequency, 150KHZ belong to the second generation of switch voltage regulator, low consumption, high efficiency.

What's in the Package:

• 1pcs LM2596 DC to DC Buck Step Down Converter Module with LED Voltmeter
