ABB UPS DPA 250 S4

Description

General features

High efficiency reduces total cost of ownership

• DPA 250 S4 can reduce energy losses by more than 30% compared to similar products in market
• Thanks to 3-level interleaved technology the DPA 250 S4 achieves an energy efficiency of over 97% in a wide operating range
• Extra VFI-double conversion mode maximizes efficiency under low-load conditions

Full flexibility to meet a variety of installation schemes

• Small installation footprint salves space DPA 250 S4 is adaptable to different installation schemes
• Variety of options for energy backup. Including lithium-ion batteries
• The DPA 250 S4’s battery charger is very powerful, ready to support the critical load in the next outage

Uninterruptible power – scalable from 50 kW up to 1.5 MW

• 50 kW power in one UPS module
• 300 kW power in one UPS cabinet
• Up to five frames and up to 30 modules can be paralleled for an amazing 1,500 kW of uninterruptible power.
• Secure ring communication ensures there is no single point of failure in the system

Easy to operate – fast and secure to maintain
