DC-AC-480V series Solid State Relay
Features
- Solid-state relays use solid-state optocoupler circuits for design and integrated circuit control. They have features such as high insulation strength of up to 2500VAC at the input and output terminals, internal surge current protection circuits, and LED display of operating status. They are very suitable for long-term use.
