VM330 Digital Voltmeter
Discover our ultra-compact mini voltmeter, ideal for precise voltage measurements in the range of 4 to 30 volts. This device is characterized by a clear 3-digit 7-segment display that shows measured values in a 0.36 inch size. The display updates every 0.3 seconds and allows an accurate reading to two decimal places.
With a minimum power consumption of less than 30 mA, this voltmeter offers efficient power monitoring without high energy consumption. In addition, it offers two practical fixing lugs for easy mounting.
For extended functionality, the device can also measure voltages from 0 to 30 V DC when a separate 4 V power supply is connected. Please note that the solder bridge on the back of the
back of the circuit board must be removed to activate the extended measurement function.
