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

The PX-BLS Series is an AC output Power Source used for mission-critical applications where loss of power would be catastrophic, highly disruptive at best.  The PX-BLS is different to a UPS, as its inverter is both dual input 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:-

 

  1. Dual Input Design:
    • Equipped with a 96V / 110V / 220V / 230V AC power supply
    • Also features a 24V / 48V / 110V / 220V DC power supply
  2. Communication Application Focus:
    • Specifically designed for the high reliability requirements of communication systems
  3. Filling a Gap:
    • Addresses a gap between traditional UPS power supplies and common pure sine wave inverter solutions
  4. Clean, Stable, and Durable AC Power:
    • Utilizes a novel design structure to provide clean, stable, and durable AC power for critical loads
  5. Seamless Conversion:
    • Dedicated communication pure sine wave inverter design ensures seamless conversion between AC and DC power supplies
  6. High Reliability:
    • Offers the same high reliability as the DC power supply system, emphasising its dependability for critical applications
  7. No Conversion Delay:
    • Boasts almost no conversion delay during the power supply transition
  8. 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 needs.  Its dual input inverter design and seamless changeover contributes to its appeal for applications where uninterrupted ac and high-quality power is crucial.
