ESCRIPTION
The YR2.DIODE is a redundancy module, which can be
used to build 1+1 and N+1 redundant systems. It is
equipped with two input channels, which can be
connected to power supplies with up to 10A output
current and one output, which can carry nominal
currents up to 20A. The module is suitable for power
supplies with constant current overload behavior as well
as any kind of "Hiccup" overload behavior.
The YR2.DIODE is the perfect solution to use in a
redundant system, if the power supply itself is equipped
with a DC-OK signal (e.g.: DIMENSION Q-Series). In
addition to the YR2.DIODE is the YRM2.DIODE which
has a monitoring circuitry included. LEDs and relay
contacts signal when one of the two DC-input voltages
is not in range due to a non-functioning power supply.
Another interesting application for this diode 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.
Unique quick-connect spring-clamp terminals allow a
safe and fast installation and a large international
approval package for a variety of applications makes
this unit suitable for nearly every situation.
