Redundancy Module
Delta Electronics adds two Redundancy Modules, DRR-20A and DRR-40A to its CliQ II series of DIN Rail power management products. They are compatible with both 24Vdc and 48Vdc power supplies, offering redundancy functionality. These modules can also be used for Parallel operation.
The Redundancy function ensures zero system down time for the customer when one of the power supply fails or is being disconnected unexpectedly. Under normal circumstances, both power supplies are each operating at approximately 50% load. When one fails, the other automatically takes over, thus providing 100% load, and ensures that the system continues running
The fault relay function alerts the user of any failure through potential free contacts. The LED lights on the Redundancy Modules also indicate the health of each individual power supply.
