The Energy Reservoir DSSB 170 is a capacitor unit intended for use with
24 V direct supply (without d.c./d.c. converter). In the event of mains
power failure, the unit provides the system with energy necessary for
storage of important data.
DSSB 170 is built up on a 19-inch apparatus plate.
The controller and the first I/O subrack require one energy reservoir.
Additional I/O subracks need a second unit.
The following description refers to the block diagram (next page).
The capacitor charging current is limited with a low-resistance power resistor.
The energy stored in the capacitors is discharged via a resistor when the unit is
disconnected from the mains power supply and the load.
Unregulated d.c. supply is connected at the terminals X1:1 - 4. The output
X2:1 - 4 supplies the 5 V regulator units with 24 V.
A serial diode prevents the energy stored in the unit from leaking back to the
supply mains in the event of a power failure.
