Power source circuit board - REGGAE
REGGAE GTbz/GTbzxxx communicators are powered by
alternating supply grid 230 V / 50 Hz The power source
circuit board is used to create direct current power vol-
tage 13 8 V for the REGGAE GT communicator The out-
put of direct current voltage from the power source cir-
cuit board is backed up by a VRLA accumulator 12 V
Powering the REGGAE GTbz/GTbzxxx communicators
Direct current power voltage 230 V is brought into the
communicator through the terminal plates marked „L“,
„N“ and „PE“ The maximum power consumption of the
communicator from the alternating current supply grid
is less than 150 mA
Back-up accumulator
The back-up accumulator is connected to the red and
black conductors of the power source circuit board (with
end fasteners) The power source circuit board ensures
the operating state of the accumulator – this means char-
ging and connection/disconnection of the accumulator
from the direct current output from the power source
circuit board The maximum charging supply of the accu-
mulator is limited to 435 mA During operation of the
power source circuit board at alternating grid 230 V, the
accumulator is constantly charged at a voltage of 13 8 V
The power source is designed to serve VRLA accumula-
tors 12 V with a capacity in the range of 1 2 to 7 5 Ah
The power source circuit board ensures automatic dis-
connection of the accumulator in cases where its open
circuit voltage falls below 8 9 V during operation of the
communicator by the accumulator (this means at times
of loss of alternating current supply voltage 230 V) Even
during the absence of alternating current supply voltage
230 V it is possible to put the communicator into opera-
tion by connecting an accumulator with an open circuit
voltage of more than 11 5 V
Supply output AUX
Supply of output AUX is achieved by using the terminal
plates marked „AUX“ and „GND“ This output is meant for
possible supply of the circuit of the voltage insulated in-
puts I1 to I7 on the circuit board of the REGGAE GT com-
municator During operation of the communicator using
the alternating grid 230 V the AUX output allows direct
current voltage of 13 1 – 13 8 V During operation of the
communicator using the back-up accumulator, voltage
of the AUX output may fall to a value of 8 5 V The maxi-
mum power consumption of the AUX output is 50 mA
The AUX output is not insulated from the remaining parts
of the communicator and so its usage for supplying any
of the inputs I1 to I7 leads to the breach of the insulation
of the inputs involved
The AUX output is protected from short-circuiting by a
return safety fuse This guarantees the limiting of power
coming from the short-circuit of the output to less than
100 mA
