The YR2.DIODE is a decoupling module, which can
be used for various purposes. The most popular
application is to configure a highly reliable and true
redundant power supply systems.
Another interesting application is the separation of
sensitive loads from non-sensitive loads. This avoids
the distortion of the power quality for the sensitive
loads which can cause controller failures.
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).
Alongside with the YR2.DIODE, there exists 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.
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.
