The UPS is connected to a shockproof socket between the
public utility's mains and the loads to be protected.
Under normal operating conditions, i.e. if PROTECT HOME. is
supplied with mains voltage, the battery charger will ensure that
the battery is always completely charged. In this case the
connected loads are supplied via the line filter, with offers a
effective protection against mains over voltage and mains
voltage peaks.
In the event of a mains failure PROTECT HOME. 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 back feed to the
mains and voltage supply to the pins of the mains connector
are thus reliably avoided.
PROTECT HOME. is an uninterruptible power
supply (UPS) for essential loads such as personal
computers (PCs), satellite TV's, telecommunication
equipment and similar devices. It consists of:
feed protection
failures (for supplying the inverter)
alternating voltage in case of power failure
