The power supply module forms the voltages
required for the relay modules and the auxiliary
relay module. The power supply module is
located behind the system panel of the protec-
tion relay and can be withdrawn after removal of
the system panel.
The power supply module is available in two
versions as follows:
SPGU 240A1:
- rated voltage U = 110/120/230/240 V ac
n
U = 110/125/220 V dc
n
- operative range U = 80...265 V ac/dc
SPGU 48B2
- rated voltage U = 24/48/60 V dc
n
- operative range U = 18...80 V dc

The voltage range of the power supply module
fitted in the relay is marked on the system panel
of the relay.
The power supply module is transformer con-
nected, i.e. the primary side and the secondary
circuits are galvanically isolated. The primary
side is protected by a fuse F1, located on the PC
board of the module. The fuse used in SPGU
240A1 is 1 A (slow) and that one used in SPGU
48B2 is 4 A (slow).

when the power supply module is in operation.
The supervision of the voltages supplying the
electronic circuits are integrated into the relay
modules. A self-supervision alarm is received, if
a secondary voltage deviates from its rated value
by more than 25%.
