The BPC PowerTower Green can be scaled in vertical modular steps up to 1200kVA of power in a single frame, providing a cost effective method of building any data centre without oversizing that can result in energy waste. 


The BPC PowerTower modular UPS operates a true hot swap technology where each power module is automatically synchronised to the load sharing of the system. The monitoring module, static transfer switch (STS) modular are also design to be hot swappable, making system maintenance easy.

The process of replacement or vertical scalability is easily achieved and hot swapping means no downtime and the service/operating personnel do not require any special skills. 


The PowerTower Green CMS offers a flexible install so assembly time is greatly reduced. Bottom and top entry with generous cable management will simplify the more difficult installation. 

Options are available for Galvanic Isolation Transformer cabinet, front 10" colour screen display, improved battery management, frequency conversion, conformal coating, input & output switchgear


The PowerTower Green CMS Series offer today's data centre management the opportunity for sustainability and future growth. With flexibility and scalability combined with lower cost of service contracts, short and long term, we can increase savings on overall operations.

  • AC - AC efficiency >96%
  • DC - AC efficiency >98%
  • Input power factor 0.99
  • N+X module level redundancy 
  • Multi-level decentralised control technology
  • Battery discharge management
  • Space saving high density design
  • Monitoring function
  • 1/3, 3/1, 1/3 and 3/3 configuration options


The PowerTower Green can deliver one of the highest power density up to 450kW/m² and requires minimal space clearance around the unit so floor space required in data centres for UPS can be kept to an absolute minimum.


The PowerTower Green offer true online efficiency over 96% at even 50% load, significantly reducing system running costs and site air-conditioning expenses, thus helping to reduce the organisations carbon footprint.
