The E series solid-state relay is a DC input control, AC zero-crossing conduction, zero-crossing output type of non-contact relay. It has the advantages of small di/dt ratio, stable starting performance, small power grid radiation interference, reduced inductive load back electromotive force when closed, and certain protection for the appliance and solid-state relay. It is the first choice for controlling general appliances such as motors, heaters and incandescent lamps.
The E Series solid state relay from BESTALL offers zero‑crossing AC conduction with DC control, providing low di/dt, reduced electromagnetic interference, and protection for inductive loads such as motors and heaters. The manual describes the relay’s operating principles, key advantages, and typical applications.
Installation instructions include mounting methods, heatsink selection, and wiring details. Technical parameters such as dielectric strength, insulation resistance, operating temperature, voltage drop, leakage current, and current rating are listed for proper selection and safe use. This manual is written in Chinese.
