A Modular UPS is where a unit is able to provide N+1 or N+X redundancy as well as being able to grow as power requirements increase. This is achieved by adding additional modules which can slot into a chassis on an individual basis. Modern-day modular parallel UPS solutions enable organizations to simply, and cost-effectively, increase their UPS power, improve availability and enjoy the long?term benefits of scalable UPS solutions that can grow insensible incremental steps as the organization grows. The result is improved efficiency, lower cost of ownership, and better customer service through high availability. We have the world's best OEMs APC Schneider & Eaton Modular online ups solutions which start from 60 KVA to 500 KVA. Each UPS module has all the hardware and software needed for autonomous operation – rectifier, inverter, battery converter, static bypass switch, back-feed protection, control logic, display, and mimic diagram for monitoring and control. With all the critical components distributed between individual units, potential single points of failure are eliminated.
