Description:

The static switch product line is a micro-controller driven state-of-the-art switch between the AC mains and the inverter to provide uninterruptible AC power. After an extremely quick detection of a mains fault, the static switch transfers the load almost without cut off to the redundant AC line. A communication and synchronization bus is responsible for the system performance and the Delta inverters are synchronized to the public AC mains. Modular UPS configurations in ON LINE or OFF LINE mode can be realized in combination with Delta inverters and DC power systems with battery backup.
