  DPA 250 S4

The DPA 250 S4 features a high-efficiency, modular architecture that delivers exceptional reliability for environmentally conscious organizations requiring zero downtime and a low total cost of ownership.

It is specifically designed for critical, high-density computing environments such as small- and medium-sized data centers.

The DPA 250 S4 sets a new benchmark for UPS technology with advanced features such as transformer-free IGBT converters utilizing three-level topology and interleaving control technology. This enables a market-leading UPS module efficiency of up to 97.6%.

The resulting high efficiency reduces operational costs while minimizing environmental impact.

High efficiency reduces total cost of ownership

  • DPA 250 S4 can reduce energy losses by more than 30% compared to similar products on the market
  • Thanks to three-level interleaved technology, the DPA 250 S4 achieves energy efficiency above 97% across a wide operating range
  • Xtra VFI double-conversion mode maximizes efficiency under low-load conditions

Full flexibility to meet a variety of installation schemes

  • Small installation footprint saves valuable space
  • Adaptable to a wide range of installation requirements
  • Multiple energy storage options available, including lithium-ion batteries
  • Powerful battery charger ready to support critical loads during extended outages

Uninterruptible power – scalable from 50 kW up to 1.5 MW

  • 50 kW power capacity per UPS module
  • 300 kW power capacity per UPS cabinet
  • Up to five frames and 30 modules can be connected in parallel, delivering up to 1,500 kW (1.5 MW) of uninterrupted power
  • Secure ring communication architecture eliminates single points of failure within the system

Easy to operate – fast and secure to maintain

  • Carefully designed electrical and mechanical architecture reduces the risk of human error and simplifies maintenance procedures
  • A module can be removed, replaced and returned to operation in as little as 10 minutes
  • Robust design with practical handling features, including mechanical stoppers that prevent modules from sliding out too far
  • Easy monitoring at both system and module level

Energy saving in action

Featuring superior UPS module efficiency of 97.6% and overall system efficiency of 97.4%, the DPA 250 S4 significantly reduces energy losses that translate directly into electricity and cooling costs.Thanks to its three-level interleaved technology, the DPA 250 S4 maintains efficiency above 97% across a wide operating range, particularly when the load is between 25% and 75% of nominal capacity.

Xtra VFI – optimized double-conversion operation at low load

Under conditions where the load is relatively low compared to the total UPS capacity, the DPA 250 S4 increases overall system efficiency by optimizing the number of modules operating in double-conversion mode.If the load suddenly increases, additional modules are automatically switched online within milliseconds, ensuring uninterrupted protection for critical loads.

Uninterruptible power – scalable from 50 kW up to 1.5 MW

One of the key advantages of a modular UPS architecture is the ability to scale capacity quickly and efficiently.The DPA 250 S4 allows system power to be matched precisely to current load requirements and expanded easily as demand grows.Equipped with smart and secure power connectors, DPA 250 modules can be added or removed while the remaining modules continue supporting the load in double-conversion mode.
