IV. POWER SUPPLIES
IV.1. DS200
The system operates on 230 VAC / 50 Hz mains input that is processed by SPS200 and
SPS248 Power Supply modules. Therefore, a single SPS200 and an SPS248 have been
included in each rack within the basic hardware structure of the system.
Yet, the DS200 system can be fed by an external AC/DC power supply of 56 VDC, if
necessary. In that case, since the SPS200 AC/DC power supplies are not used, the SPS248
DC/DC power supplies may be used as a backup, upon wish. (In that case, the BPL200-
SPSX backplane must be used, too.)
IV.1.A. THE AC/DC POWER SUPPLY - SPS200
Definition:
SPS200 is a Switched Mode Power Supply that operates on the mains voltage (SMPS).
Appearance of the SPS200 AC/DC Power Supply is illustrated in the figure below.

The SPS200 AC/DC Power Supply converts 230 V AC to -56V DC, which is the input value
for the SPS248 DC/DC Power Supply. SPS200 can also feed the system through batteries
and it can charge the batteries while being fed from the mains. In addition to that, it protects
the exchange from adverse factors that may affect through the electric system.
