double mains filters which provide effective protection against

mains voltage peaks and high-frequency faults.

In case of sustained mains undervoltage or overvoltage within

defined ranges, the automatic voltage regulator (A.V.R.)

further stabilises 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 A. 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.
