The SPS200M AC/DC-DC/DC Power Supply first converts 230 V AC to –56 VDC within itself.
Then, it converts the -56 VDC output to the voltage levels of +5 VDC, -5 VDC and -48 VDC
that are required for system operation. Besides, there is a ringer transformer on it for
generating ringer signal (67 Vrms.) The power supply can also feed the system through the
battery and it can charge the battery while being fed from the mains voltage. In addition to
that, it protects the exchange from adverse factors that may affect through the electric
system.
SPS200M Power Supply contains a metal casing to which the Power Card is connected.
