ABB’s SG Series is one of the most efficient and reliable three-phase UPS systems available, providing outstanding output performance and reliable power protection for your critical application needs. SG Series UPS solutions are designed and optimized to provide high efficiency at part-load conditions too.

• High efficiency: up to 94.6 percent in double conversion mode and up to 99 percent in eBoost mode. eBoost is available on 160-500 kVA models
• eBoost operation minimizes losses and can save annual power and cooling costs of up to $300k for a 5 MW data center (based on typical figures)
• The PurePulse IGBT rectifier keeps your supply network clean and compact by shrinking the circuit breaker, cabling and generator

The SG Series UPS ensures low input current harmonic distortion and excellent output voltage regulation and dynamic response, thus reducing operational costs – all in an environmentally friendly solution.

Easier installation and configuration flexibility

• True front access for operation and maintenance reduces mean time to repair (MTTR)
• Small footprint
• The redundant parallel architecture delivers reliability, redundancy and scalability
• Up to six UPS frames can be paralleled

High performance and availability

• Enhanced output performance that protects and supplies even the most sensitive IT loads with a lagging-leading power factor (0.9) without derating
• Excellent dynamic performance and low output voltage distortion
• Inverter zig-zag isolation transformer provides outstanding short-circuit capability and load galvanic separation
