New Slimline Redundancy Modules from MEAN WELL

ADM is stocking MEAN WELL’s new range of slimline redundancy modules, the DRDN20 and DRDN40 series.

MEAN WELL slimline redundancy modules

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).  

The below table sets out the orderable part numbers: 

Part Number / Link

Output Voltage Range

DRDN20-12

9~14VDC 

DRDN20-24

19~29VDC 

DRDN20-48

36~60VDC 

DRDN40-12

9~14VDC 

DRDN40-24

19~29VDC 

DRDN40-48

36~60VDC 

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 manufacturer’s warranty.
