Smart Power Supply S8AS A New Type of Power Supply That Provides Safety and Maintainability 240- and 480-W power supplies with and digital circuit protectors in a single package. Each branch output tripping current value can be easily set at 0.1-A increments. Startup and shutdown sequence control included. Various monitor displays and alarms (output voltage, output current, maintenance forecast monitor, temperature). Conforms to UL Class 2 Mounts to DIN Rail. For the most recent information on models that have been certified for safety standards, refer to your OMRON website.
