SSW Series static switch

Description

The Delta SSW Series static switch is an electronic switch between the AC mains and the Delta API 1500A series modular inverters to provide an uninterruptible AC power for the equipment. Two standard static switch modules rated for 7.5kVA and 30kVA are available. The static switch is responsible for the system performance and the Delta API 1500A series modular inverters are synchronised to the AC mains. For energy cost saving reasons, the static switch can be configured to offline mode, where the AC utility is connected to the equipment directly. The inverters will be backup energy source in case of AC utility quality decrease or AC utility failure. Installation is simplified as all Delta static switches have their connectors at rear and are hot-pluggable. Fan cooling with speed control ensures near-silent operation.

Main features

• Energy saving up to 5 % due to architecture
• Energy saving up to 14 % due to Offline system configuration
• High-quality AC supply to critical telecom equipment in harsh environment due to Online system configuration
• High-performance AC line quality monitoring
• Inbuilt AC overvoltage protection
• Very fast switchover at mains failure
• Synchronisation of the inverters to the AC utility

Applications

SSW Series static switch is used in Delta CellD, MidD,
CabD and OutD systems for:
• Backup AC power for infrastructure equipment
• Network base stations
• Wireless applications
• Fixed line applications, data communications
