Vertically and horizontally scalable
The DPA 500 provides power protection from 100 to 500 kW (one to five modules) in a single cabinet (vertical scalability). The cabinets can operate in a parallel configuration to form a system of up to 3 MW (horizontal scalability).
True parallel architecture
The advanced UPS design of the DPA 500 provides the highest degree of protection in critical applications where the load needs to be supplied with quality power. This UPS system uses decentralized parallel architecture, providing the highest level of reliability and availability with true redundancy between modules.
