Description: Accurate and Reliable Measurement: The DC Voltage Meter uses a redundant ADC chip for high measurement accuracy up to 0.1% FS. It has a wide measurement range, capable of measuring DC voltages from 11V to 310V. The meter provides stable and reliable measurements with strong anti interference capabilities.Clear LED Display: This voltage meter features a large sized LED digital tube display, making the numbers easy to read. It displays voltage values, units, and working state among other information.Easy Installation: With its standard installation method, the LED Voltage Meter Indicator is easy and quick to install. Its compact design saves space.Intelligent Recognition and Automatic Adjustment: The Digital Voltmeter intelligently recognizes the input voltage range and automatically adjusts the decimal point position in the display accordingly. Depending on different voltage ranges, it automatically selects the appropriate measurement accuracy.Multiple Protection Features for Safe: The Din Rail Mount Digital Voltage Meter comes with multiple protection features including overvoltage protection, overcurrent protection, short circuit protection etc., ensuring safe usages of this device at all times. Both input and output ends use an isolated design for added safe.
