ABB’s DPA 500 is a high-power, modular and transformer-free UPS system for organizations who need zero downtime. The DPA 500 is the only modular UPS on the market that can easily be scaled up to provide 3MW of clean, reliable power. Each module contains all the hardware and software required for full system operation. They share no common components. Each UPS has its own independent static bypass, rectifier, inverter, logic control, control panel, battery charger and batteries. With all the critical components duplicated and distributed between individual units, potential single points of failure are eliminated.
