Delta Electronics SSW 230V-6kVA, SSW 230 V - 20 kVA User Manual

The Static Switch Product Line

SSW 230V-6kVA →

SSW 230 V – 20 kVA →

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.
