Hardware - SIMADYN D
Edition 04.2011
Test sockets to check the 3 output voltages 5 V, +/-15 V
(short-circuit proof)
The line supply voltage is connected through the 3-pole screw/plug-in
terminal X1.
The connection assignment is printed on the front panel:
Above the voltage selector switch (Slide switch) can be switched to between
an input nominal voltage from 230 V and 115 V.
The in each case valid value becomes visible with transfer of the switch.

For SR12.x:
In = 16 A max..
I²t= 6 A²s
Is = 32 A
(inrush peak)
For SR24.x:
In = 32 A max..
I²t= 10 A²s
Is = 64 A
(inrush peak)
For SR12.x: (AC230V)
In = 1.2 A max..
I²t= 0.6 A²s
Is = 6 A
(inrush peak)
For SR24.x: (AC230V)
In = 2.7 A max..
I²t= 1 A²s
Is = 9 A
(inrush peak)
X2 pins 1 - 4 Monitoring the power supply and fan assembly (relay)
X3 pins 1 - 2 Feed for an external back-up battery
X4 pins 1 - 2 Reset: A reset is initiated by jumpering the contents (optional to
using the reset button)
The specified current In is the current that can occur at a maximum insertion
of the subrack. The power supplies are in part oversized, and have a higher
maximum input current (Chapter: Technical dates).
NOTES
The
protective conductor
must be connected at connector X1, pin 3.
It is not sufficient to connect a protective conductor at the subrack.
It must be a slightly accessible circuit breaker in the supply circuit.
Interface modules
with binary output function
SB70, SB71
should be
powered-up approximately 200 ms before the modules are powered-up
to prevent power-on effects.
This is achieved by
simultaneously powering-up
the subrack power
supplies (this requires approximately 200 ms to establish the voltages)
and the interface modules.
