The CNC AD16-22DV is a miniature digital indicator voltmeter designed for real-time monitoring of AC voltages between 20V and 500V. With a 22mm panel mount diameter, it fits standard control panels and distribution boards. The device features a bright LED display available in five colors (Red, Green, Yellow, Blue, White), offering clear voltage readouts. Built to withstand harsh environments, it operates reliably under vibration (2–80Hz, 0.7g) and high humidity (≤98%), with a rated temperature of T90. Its continuous working life exceeds 30,000 hours, and it complies with IEC standards for industrial-grade performance.
