UPS systems Uninterruptible power supply

UPS systems

Uninterruptible power supply (UPS) systems are used in almost every area of daily life. UPS systems play a vital role in providing protection against voltage peaks and power cuts. These systems are used whenever it is important to have a consistent, regular and constant supply of power, such as backup power supply systems.

What is an offline UPS systems (VFD) (Voltage and Frequency Dependent)?

The inverter is connected as a replacement power supply parallel to the mains and is only active when required. During normal operation, the UPS system simply keeps the battery charges. The load is supplied directly from the mains by means of a filter. The inverter is in stand-by mode.

If the mains is not available or the mains voltage lies outside the specified tolerance, the power supply is assumed by the battery and the converter following a switching period defined by the manufacturer.

The battery operation continues until the autonomous life of the battery ends.

What is an line interactive UPS systems (VI) (Voltage Independent)?

With line interactive UPS systems, the inverter is used as a replacement power supply parallel to the mains supply and simultaneously charges the battery. Therefore, the inverter serves two operational purposes coupled with the mains supply:

During normal operation, the load from the mains supply and the converter branch is supplied with the appropriate voltage. The converter controls the output voltage and charges the battery when necessary. However, the output frequency is determined by the mains frequency.

If the voltage exceeds or falls below the UPS system’s specified tolerance or in the case of a collapse, the load supply is cut off from the mains by means of a static switch and exclusively provided with an uninterrupted supply of power from the battery and the converter branch.

What is an online UPS systems (VFI) (Voltage and Frequency Independent)?

In online technology, the UPS system is serially connected between the network and the device. In normal operation, the supply is provided through a chain of rectifiers and inverters according to the double conversion principle, with a dual transformation of AC voltage to DC voltage back to AC voltage.

If the mains supply exceeds or falls below the UPS system’s specified tolerance or if there is a complete collapse, the power supply to the device will continue uninterrupted - meaning without any control means - via the battery and the inverter.

How long this operation lasts for depends on the autonomous life of the battery installed.

Customers around the world rely on JOVYATLAS UPS systems to prevent damage or downtime which would otherwise be caused by power failures, excess voltage or undervoltage, frequency variation or harmonics. We provide a comprehensive range of UPS systems to suit almost any application.

Monoblock and modular UPS systems

JOVYATLAS designs and manufactures single phase UPS systems covering a range from 1000 VA to 10 kVA for a wide variety of technical applications. 3-phase UPS systems (tower and 19 inch rackmount) covering 10 kVA to 800 kVA per system. System solutions in the MVA range are also available. We also design and manufacture modular UPS systems in different sizes.
