Power supply system SITOP PSU8600
Another variant uses the SITOP PSU8600 power supply system. The basic unit
with four selectively monitored outputs is extended by an expansion module with
four selectively monitored outputs (CNX8600). Using the (BUF8600) buffer module,
it is possible to bypass brownouts. If the short-term bridging with the buffer module
is not sufficient, a longer period can be bridged with the UPS module (UPS8600)
and the batteries connected to it (BAT8600).
