Product Introduction

The TOVS-16Z is a compact voltage monitoring and protection device designed for AC 100–300V systems with a maximum load current of 16A. It combines real-time voltage measurement with adjustable overvoltage and undervoltage protection to safeguard connected equipment from abnormal power conditions. Key features include automatic recovery after fault conditions, a clear voltage display, and user‑adjustable voltage calibration (±9.5%). Protection thresholds, action times, and recovery delays are fully configurable, allowing precise adaptation to different applications. With a robust electromechanical life of 100,000 operations and low power consumption under 2W, the TOVS-16Z delivers reliable and intelligent voltage monitoring and protection.
