SITOP modular,
PSU8600 power supply system
Modular system, buffer (BUF8600)
■
Overview
The BUF8600 buffer modules with maintenance free energy
storage units are part of the SITOP PSU8600 modular system
and are designed to bridge short-term power failures. They
automatically take over the DC power supply in case of a line
voltage failure. You can connect up to two BUF8600 buffer
modules to the PSU8600 basic unit. Connection takes place on
top of the modules without any wiring by means of the System
Clip Link, a connecting plug for system data and power supply.
Main product highlights
•
Reliable bridging of short-term power failures up to maximum
20 s (at 24 V DC and full load)
•
Buffer module with maintenance free electrolytic capacitors
for bridging short-term power failures (brownouts) between
100 ms and max. 600 ms (at 24 V DC/40 A)
•
Buffer module with maintenance free double-layer capacitors
for bridging longer power failures between 4 s and max. 20 s
(at 24 V DC/40 A)
•
The two buffer modules can be combined as required.
•
Easy connection without wiring overhead
