PXe-UH series Uninterruptible Power Supply | UPS

The PXe-UH series Uninterruptible Power Supply (UPS). Is a double conversion system with a sine wave output that provides a high level of power protection for critical applications.
Its features include:
  1. Double Conversion System: The UPS constantly converts incoming AC power to DC and then back to AC. This process provides a consistent and clean power output, free from most types of power disturbances.
  2. Sine wave Output: A sine wave is a smooth and continuous waveform that closely mimics the form of utility power. Devices, especially sensitive electronics, often prefer sine wave power to function optimally. The PXe-UH series provides a sine wave output ensuring compatibility with a wide range of equipment.
  3. Continuous, Stable, Clean Power: The UPS ensures a steady and clean power supply, which is crucial for the reliable operation of mission-critical equipment in commercial and industrial settings.
  4. Battery Backup: In the event of a utility power outage, the UPS seamlessly switches to battery power to prevent any interruption in the power supply. This is crucial for users who cannot afford downtime.
  5. Protection for Commercial and Industrial Environments: The UPS is designed to meet the power protection needs of both commercial and industrial settings, where reliable and uninterrupted power is often essential for critical operations.
Overall, with these features, the PXe-UH series Uninterruptible Power Supply (UPS) is a robust solution for businesses and industries that require a high level of power protection to safeguard their mission-critical equipment and processes.


PXe-UH series Uninterruptible power Supply
The PXe-UH UPS (Uninterruptible Power Supply) system incorporates a variety of features:
  1. Advanced Digital Controller:
    • The UPS utilises an advanced digital controller to manage its double conversion system. Double conversion systems are common in UPS units and provide a consistent, high-quality power output by converting incoming AC power to DC and then back to AC.
  2. Isolated Transformer at the Output:
    • The presence of an isolated transformer at the output is a crucial feature. This component helps protect both the connected load and the UPS itself from power irregularities, surges, or other electrical disturbances.
  3. User-Friendly LCD Interface:
    • The built-in LCD interface makes it easy for users to interact with and monitor the UPS. This could include displaying important information such as input/output voltage, battery status, and other relevant metrics.
  4. Multiple Communications:
    • The UPS offers various communication options, including Modbus and RS-232. These are standard communication protocols used in industrial automation and control systems, allowing the UPS to integrate with other devices and systems.
  5. Intelligent Slot:
    • The presence of an intelligent slot enables the  UPS to be designed to accommodate additional modules or features. This could include network cards for remote monitoring or other expansion options.
  6. Remote Monitoring and Control:
    • The inclusion of free downloadable software enables the UPS to be remotely monitored and controlled. Users can access critical information and manage the UPS functions from a central location.
The UPS is well-equipped with features that enhance its performance, protect connected devices, and allow for convenient monitoring and control. The emphasis on remote capabilities and communication options makes it suitable for integration into larger systems where centralised control and monitoring are essential.
