Yokogawa AR-PH Arrester for Power Supply

Overview

The Yokogawa AR-PH surge arrester is designed to protect power supplies from transient overvoltages, particularly from lightning strikes or electrical disturbances. It safeguards electronic instruments such as transmitters and receivers by absorbing induced surge voltages. This arrester is suitable for various industrial applications where power supply protection is crucial.
