The power supply system for Advant Controller 450 includes a battery package intended for
current supply for RAM and the system clock in the event of a power failure in the controller
subrack.
The Ni-Ca battery included in Battery Unit SB522 is kept charged by a Backup Power Supply
SB510 or SB511.
SB510 is used at 110-230 V a.c./d.c. supply voltage.
SB511 is used at 24-48 V d.c. supply voltage.
The backup power supply is supervised. Status is available to the controller diagnostic system.
Status is also indicated by LEDs on the backup power supply module front.
Battery capacity is four hours in a single CPU system and two hours in a redundant CPU
system.
For further technical data, see
Chapter 3, Configuration/Application Building
and the respective
module descriptions in
.
Please note that you can use an optional network C, which maintains battery-charging and
supply of the RAM while the power supply is otherwise switched off.
If a longer backup time is desirable, you can also use the alternative backup power supply unit
SB511 connected to a 24 V or 48 V external battery system. Isolation is provided by SB511.
Max input power to the backup power supply is 25 VA. The resulting backup time at for
example 24 V, is then better than 1.5 h per 1 Ah external battery capacity (single processor
module) or 1 h per 1 Ah external battery capacity (redundant processor modules).
The internal battery SB522 must be in position to get the normal diagnostics of the SB511.

The fusing and electronic overload protection of the Advant Controller 450 and its main parts
are illustrated in
(DUWKLQJ
The signal processing electronics in Advant OCS are normally earthed to chassis and all
interference suppression for external signals refers to chassis. If this rule is broken, the system is
sensitive to high-frequency interference, mainly interference from unsuppressed relays, to
contactors and to discharge of static electricity.

Auxiliary equipment in the controlled system is normally powered separately. This means
separate power supply units and fusing. However, given a small current requirement, and if you
follow the rules given in
Section 3.1, Design Considerations
, you can also use the system power
supply unit for field equipment.
The series of power supply units listed in
is, of course, generally applicable.
