## Description

Mini module for fast DC voltage monitoring, with 0.28 inch blue display and clear 3-character readout. Measures 0-100VDC, operates at 4-30VDC and uses 3-wire connection for simple installation with common ground. Low power consumption below 20mA, automatic decimal point and mounting lugs for stable mounting.
Mini voltmeter module with 0.28 inch display, Blue color, which can display a voltage between 0 and 100VDC.
It is provided with 3 wires, two for power and the third for voltage measurement. Attention , the supply voltage is between 4 and 30 VDC . The supply is made through the Red and Black wires. The third wire (White or Yellow, depending on the batch) will be placed on the Cathode (+), which actually measures the voltage. To work, it is necessary that the circuit has a common GND.
The module has mounting ears. of 33mm.
The decimal point moves automatically.
