GENERAL DESCRIPTION

SHORT-FORM DATA

The YRM2.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 YRM2.DIODE has a monitoring circuit included and
is the perfect solution when the power supply has no
DC-OK function. Two LEDs and two relay contacts signal
when one of the two DC-input voltages is not in range
due to a non-functioning or disconnected power supply.
In addition to the YRM2.DIODE is the YR2.DIODE which
has no monitoring circuitry included. This is the perfect
fit when the power supply itself is already equipped
with a DC-OK signal (e.g.: DIMENSION Q-Series).
Large screw terminals allow an easy installation and a
huge international approval package for a variety of
applications makes this unit suitable for nearly every
situation.
