Pure Sine Wave Inverter

The PX-BLS Series Pure Sine Wave Inverter is a sophisticated and versatile solution designed for communication applications. Rack mountable and east to store, 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, emphasizing 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 switch in the conversion process.

In summary, the PX-BLS Series Inverter is tailored to meet the demanding requirements of communication systems by offering a reliable and efficient solution for power supply needs. Its dual input design and seamless conversion capabilities contribute to its appeal for applications where uninterrupted and high-quality power is crucial.
