The regulator SR511 is a switch-mode power converter transforming
24 V d.c. to the stabilized voltages 5 V and 2.1 V d.c.
All of these voltages have a common negative terminal.
The SR511 is designed as a plug-in device and is positioned in a
controller subrack to interface with the backplane bus.
Use the regulator in equipment where the regulator output
terminals are connected in parallel to other regulators of the same family.
Thus, n regulators can share the load giving an arbitrary capacity of power,
and where adding an extra regulator to the stack, the (n+1) -redundant
power supply system is derived.
In an Advant Controller 450, use two SR511s to achieve redundancy.
You can exchange one regulator at a time in a redundant regulator
live system without generating malfunction.
Two 24 V power supply networks with a common negative terminal
can connect to the SR511 via the subrack power bus.
The 5 V output is rated 35 A load, exclusive of the current delivered by
the 2.1 V output.
Use the 2.1 V output to power the parallel bus termination.
An SR511 includes a supervisory logic circuitry signalling the normal
status by closing a semiconductor switch, thereby connecting the signal
output terminal to ground via a 100 ohms resistor.
A faulty or missing unit leaves the signal terminal open.
