UPS Systems Wärtsilä JOVYTEC L

6000 VA, 8000 VA, 10000 VA

The Wärtsilä JOVYTEC L series UPS systems are equipped with an integrated output transformer for the galvanic isolation of the devices from the input mains. This galvanic isolation is an indispensible requirement in certain operational areas such as the IT sector or in medical environments. Thanks to this capability, the Wärtsilä JOVYTEC L series UPS systems meet the standards for VFI-SS-111. All UPS systems of this series are equipped with a performance-related fan control and a so-called power factor correction (PFC), which provides sinusoidal power consumption. The output voltage of all Wärtsilä JOVYTEC L UPS systems is equally sinusoidal. The user can easily choose one of four different operation modes via control and display panel:

Online Mode

Online Mode according to VFI-SS-111: With this type of operation, the device is permanently supplied with power by means of the inverter, which provides top-quality sinusoidal voltage. In the case of a mains failure, there is no interruption to the supply of power to the device.

Green Mode

In Green Mode operation, the device is normally only supplied via the bypass. However, if voltage fluctuations or a mains failure occur, the inverter will take over the supply to the device. Intelligent software ensures that the switchover takes place with nearly no interruption.

Freewheeling Mode

In Freewheeling Mode, the UPS system’s input frequency can fluctuate. Regardless of the input frequency - which can vary between 45 and 65 Hz - Wärtsilä JOVYTEC L systems constantly supply the device they are connected to with a predetermined output frequency.

Generator Mode

In Generator Mode, the Wärtsilä JOVYTEC L series systems prevent the regular switching when contortions occur in the generator’s output voltage. This mode of operation considerably reduces the load on the batteries. At the same time, a high degree of operational reliability is ensured.
