Description

Product Overview

KP5-VA rated voltage AC 380V, frequency 50/60Hz, supports full range monitoring of three-phase voltage, with a measurement accuracy error of ≤ 2% for each phase voltage, ensuring accurate perception of power grid anomalies. The product is equipped with a flexible parameter adjustment system: the overvoltage protection value can be customized within the range of 400V~450V (default 420V at the factory), and the undervoltage protection value covers the range of 320V~360V (default 340V at the factory). It also supports logic settings for phase loss and reverse phase sequence protection. Provide adjustable functions of 1-500S recovery delay and 0.1-30s action delay, effectively avoiding the impact of frequent start stop on the equipment.
Made with industrial grade components, the electrical lifespan is up to 10 ⁵ times, the mechanical lifespan is up to 10 ⁶ times, the protection level is IP20, and it can operate stably in ambient temperatures ranging from -30 ℃ to+70 ℃ and at altitudes below 2000m. Equipped with a three-phase voltage dynamic display window, all parameter configurations can be completed through simple buttons, balancing professionalism and ease of use. It is the core component that ensures the safe and stable operation of the three-phase distribution system.
