Product Overview
The 1606-XLBRED20 is a redundancy module, which can be used to build 1+1
and N+1 redundant systems. The 1606-XLBRED20 redundancy module has two
input channels, which can be connected to power supplies with up to 10 A
output current. The module has one output, which can carry nominal currents
up to 20 A.
The module is suitable for power supplies with constant current overload
behavior and any kind of “hiccup” overload behavior. The 1606-XLBRED20 is
well suited for use in a redundant system in which the power supply itself is
equipped with a DC-OK signal.
Another application for this redundancy module is to separate sensitive loads
from non-sensitive loads. This avoids the distortion of the power quality for
the sensitive loads, which can cause controller failures.
