full galvanic isolation transformer (standard Comet equipment)

This option is required to achieve a downstream neutral system different from the upstream neutral system. The transformer, installed in a cubicle of the same design as the Comet cubicle, must be positioned:

between the low voltage switchboard and the input power switch for Comet series 11 and series 33 (see figure 26);

between the Comet load output terminals and the load for Comet series 31 (see figure 27).

Comet TM 5 - 30 kVA specifications

MGE UPS Systems Comet TM 5 - 30 kVA is a reliable and efficient uninterruptible power supply (UPS) designed to ensure the smooth operation of critical systems in various applications. This UPS is particularly suited for data centers, telecommunications, and industrial environments that require high availability and robust power protection.

One of the main features of the Comet TM series is its modular design, which allows users to scale the UPS capacity as needed. This flexibility is crucial for businesses that anticipate growth or fluctuating power requirements. The UPS is available in a range of capacities, from 5 kVA to 30 kVA, allowing for tailored solutions that fit specific power needs.

The Comet TM is equipped with advanced double conversion technology, which provides clean and reliable power, isolating the connected equipment from input voltage disturbances. This technology ensures that any fluctuations in the mains supply, such as voltage sags or surges, do not affect the operation of sensitive electronic devices. Additionally, this UPS features a wide input voltage range that contributes to improved efficiency and reduced energy consumption.

An impressive aspect of the Comet TM is its high-efficiency mode, which optimizes energy consumption while maintaining power quality. This mode reduces operating costs and contributes to lower carbon footprints, making it an environmentally friendly choice. Furthermore, the UPS incorporates intelligent battery management systems, which enhance battery performance and extend their lifespan. This is essential in minimizing downtime and ensuring that backup power is readily available when needed.

The user-friendly interface of the Comet TM allows for easy monitoring and management of the system. With graphical displays and comprehensive alarms, users can promptly identify potential issues and take corrective actions. Remote management capabilities are also built into the system, enabling users to monitor and control the UPS remotely, which is particularly beneficial for businesses that operate across multiple locations.

In summary, the MGE UPS Systems Comet TM 5 - 30 kVA is designed for organizations that need reliable power protection and high efficiency. With its modular scalability, advanced double conversion technology, high-efficiency mode, intelligent battery management, and user-friendly interface, the Comet TM series stands out as a robust solution for critical power applications. Its combination of features ensures that businesses can maintain uninterrupted operations while benefiting from cost savings and a reduced environmental impact.
