Description:
The regulator SR511 is a switch-mode power converter transforming24 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 acontroller 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.
