Power supply system SITOP PSU8600
The PSU8600 basic module has four 24 V feeders that are switched-off individually
in the case of overloading. An expansion module CNX8600 for four additional 24 V
branches with selective monitoring is connected to the basic module. You can set
the current response thresholds individually for each output. A buffer module
BUF8600 is plugged in for so-called brownouts. In addition, the UPS8600 UPS
module, in conjunction with the BAT8600, is available for power failures over a
longer period of time.
