This is a practical power supply kit; the voltage display or voltmeter function can be switched freely by switching the toggle switch! The output power supply has a wide range, adjustable between DC1.25-14.5V, and can output a higher voltage than ordinary power supply kits! With the voltage measurement function, it can test the voltage at any point of the external module by turning the toggle switch to the voltage test terminal.

Product Features:
1. 1.25-12V adjustable regulated output, output current 200mA, suitable for powering small DIY circuits.
2. One adjustable signal generator output. It is convenient to provide pulse signals to the test circuit.
3. Logic pen function. Convenient to test the logic level of the circuit.
4. Equipped with a 1-way buzzer. You can test the continuity of the wire (connect the wire to the positive and signal input terminals of the power supply; the buzzer will sound if the wire is connected). You can also test low-frequency signals (input the signal from the signal input terminal; if there is a signal, the buzzer will sound)
