YR2.DIODE

Y-Series

Recommendations for the configuration of redundant power systems:

•

Use separate input fuses for each power supply.

•

Use three-phase power supplies to gain functional safety if one phase fails.

•

When single-phase power supplies are utilized connect them to different phases or mains circuits if possible.

•

Set the power supply in “Parallel-Use” mode if this feature is available

•

It is desirable to set the output voltages of all power supplies to the same value.

The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.

1+1 Redundancy up to 10A requires two 10A power supplies and one YR2.DIODE redundancy module.
