MEAN WELL’s New Range of Slimline Redundancy Modules

9 July 2020

MEAN WELL has recently launched two new series of slimline redundancy modules. 

The DRDN20 and DRDN40

Both series have 2 input channels and 1 output channel, and are available in 12VDC, 24VDC, or 48VDC models.   

The input channels have voltage alarm relays to allow you to integrate the module with a PLC, or other control system.   

The DRDN20 series has a power output of up to 20A per channel (continuous), whereas the DRDN40 gives you up to 40A (continuous).   

These new redundancy modules can be used in conjunction with a MEAN WELL DIN rail power supply as part of a 1+1, or N+1 redundancy system.  

The new MOSFET design has resulted in a lower voltage drop of 0.3V, as opposed to 0.6V on the older DR-RDN20 redundancy module.   

You also have the advantage of a wide operating temperature range of -40 ~ +80°C, with no derating up to 60°C.   

The MEAN WELL DRDN20 and DRDN40 redundancy modules come with a 3-year warranty.
