LM2596 Step Down DC / DC voltage regulator with display from 4-40V to 1.25-30V

Features

• With voltmeter display
• Advanced microprocessor, voltmeter error ± 0.05V, range 0 ~ 40V.
• Note: To ensure the accuracy of the voltmeter, please make sure the input voltage is above 4V
• Tap the button to toggle between input and output voltage measurement, and there is a light to show which voltage is being measured and the setting is saved, even if the power is turned off and on again
• The voltmeter can be turned off by tapping the left button
• With terminal blocks, it is easy to use without a soldering iron, and the connection points of the solder wires are reserved
• Input voltage 4.0 ~ 40V (The input voltage should be 1.5V higher than the output voltage.)
• Adjustable output voltage range 1.25V ～ 37V continuously adjustable (the input voltage should be 1.5V higher than the output voltage)
• The maximum output current can be up to 3A, and the normal stable working current is 2A
• Uses 150KHz internal oscillation frequency, belongs to the second generation switching voltage regulator with low power consumption and high efficiency
• With overheat protection and short circuit protection function
