PXe-BLS Dual Redundancy Pure Sine AC Source for mission critical loads

The PX-BLS Series AC output Power Source is used for mission-critical applications where loss of power would be catastrophic or highly disruptive at best.  The PX-BLS is different to a UPS, as its inverter is power from two energy sources, meaning it is both dual input fed and intelligent – designed to draw energy from 2 or more ac or dc sources. Rack mountable and easy to install, its key features are listed below:-

Dual Input Design:

  • Equipped with a 96V / 110V / 220V / 230V AC power supply
  • Also features a 24V / 48V / 110V / 220V DC power supply

Communication Application Focus:

  • Specifically designed for the high reliability requirements of communication systems

Filling a Gap:

  • Addresses a gap between traditional UPS power supplies and common pure sine wave inverter solutions

Clean, Stable, and Durable AC Power:

  • Utilises a novel design structure to provide clean, stable, and durable AC power for critical loads

Seamless Conversion:

  • A dedicated pure sine wave inverter that ensures seamless conversion from both AC and DC power supplies

High Reliability:

  • Offers the same high reliability as DC power supply systems, emphasising its dependability for critical applications

No Conversion Delay:

  • Boasts minimal conversion delay during its changeover from available energy sources of ac or dc

No Need for Static Switch:

  • Eliminates the need for a static changeover switch in the conversion process

In summary, the PX-BLS Series Inverter meets the demanding requirements of critical applications, like communication systems, by offering a triple redundant reliable fail-safe solution for critical power supply applications.  Its dual input inverter design and seamless changeover contributes to its appeal for applications where uninterrupted ac and high-quality power is crucial.
