stabilizes the load voltage. As a result, voltage fluctuations in the public utility's mains are reduced to a level which is acceptable for the loads. This is performed without recourse to the internal energy storage, something which in turn has a positive effect on battery availability.

The static bypass switch is activated in the event of a mains failure. The inverter then takes over the voltage supply of the connected loads, in order to prevent the risk of data loss or damage to the loads. PROTECT B. supplies voltage until the battery is discharged, allowing you to shut down your IT system properly and switch it off. The standby time mainly depends on the connected loads. If the mains power supply is back to normal values, the UPS will switch back the loads to mains supply. The battery charger will then recharge the battery.

For safety reasons (as required by German standards, VDE), the mains input in the unit will be disconnected by a two-pole switch in the event of a mains failure. Energy backfeed to the mains and voltage supply to the pins of the mains connector are thus reliably avoided.

Furthermore, additional protective measures ensure effective protection for the data/network interface.
