The YR2.Diode is a decoupling module, which can be used for various purposes. The most popular applications
are redundant power source systems and separation of sensitive loads from non-sensitive loads, which can
distort the power quality of the 24V bus and causes controller failures.
Short-form Data Approvals
Input 1 DC 10-60V, 0-20A continuous operation
DC 10-60V, 0-30A for 4s
Input 2
DC 10-60V, 0-30A for 4s
Output 0-20A continuous operation
0-30A for 4s
Voltage drop 0.9V V
Peak current 150A for 10ms each input
Reverse current < 2mA each input
Dimensions 32 x 124 x 102mm width x height x depth
Ensure that the continuous output current does not exceed 25A.
Check the short-circuit current of the power sources and if the power source
can deliver more than 25A, use an appropriate fuse on the output.

Use appropriate copper cables, that are designed for an operating temperature of
60°C (for ambient up to 45°C) and 75°C (for ambient up to 60°C) minimum.
Follow national installation codes and regulations! Ensure that all strands of a
stranded wire enter the terminal connection! Up to two stranded wires with the
same cross section are permitted in one connection point.
