DC Voltmeter Ammeter with LED Display [10A , 100V]

The digital voltage and current display module is a widely used and precise tool for measuring voltage and current in electronic and industrial projects. This multi-purpose module can be used as a voltmeter, ammeter, battery charge current display, and also a voltage meter in various systems. The design of this device is such that it consists of two three-digit seven-segment displays. One of the displays shows voltage up to 99.9 volts with an accuracy of one decimal place, and the other shows current up to 9.99 amperes with an accuracy of two decimal places. The DC voltage and current display, due to its simple and legible design, is a suitable option for use in various electrical projects. This module, with small dimensions of 48×29×22 millimeters and light weight, has the ability to be easily installed in different panels. The measurable voltage range of this module is between 0.0 and 100 volts, and it shows current in the range of 0 to 10 amperes. Its energy consumption is less than 20 milliamps, and it can be used for a long time without putting pressure on the power source.

The two-color panel-mount voltmeter and ammeter module, with the ability to select red and blue or red and red display colors, in addition to beauty, provides suitable legibility in bright and dark environments. This feature allows the user to easily view the data even under difficult working conditions. The length of the connection wires of this module is 15 centimeters, which makes its installation more flexible. The digital voltage and current display, as a modern replacement for old analog voltmeters, has greater accuracy.

Wiring:

• The Thin Red Line (VCC): Power supply input positive (3.5-30V)
• The thin black line (GND): Power supply input negative (3.5-30V) and the measurement signal common ground
• Thin yellow line (VIN): measuring signal input positive (0-100V, 100V version) (0-33V, 33V Version)
• The thick red line (I +): Current input positive (negative power supply must be connected in series)
• The thick black line (I-): Current input negative (negative power supply must be connecte

Note: If the measured signal is below 30V and can be used directly as a module supply adequate power supply (the thin yellow lines and thin red line in parallel).
