Product Description And Application

WBV414U01 converts AC input voltage into a load independent output signal dc (0)4-20mA. It has adopted electromagnetic isolation principle and average measurement method for real time measurement of AC voltage (sine form) from electric net or electric circuit.

The product has certain advantages of total galvanic isolation between input/output and auxiliary power, high accuracy, low drifting by temperature, and wide temperature bearable range, etc.
