MEAN WELL Slim-line Enclosed Power Supply with Redundancy Operation

Power Supply with Redundant Function
MEAN WELL Power Supply

The rise of modern technologies drives innovation on power supplies that suit the demands of precision instruments.  

Numerous applications requiring 24/7 operations rely heavily on stable and uninterruptible power connection – this includes data centres, telecommunication systems, medical facilities and even households with sensitive equipment, and up-to-date appliances.  

To safeguard continuous operations, it has now become a common practice to have a redundant power set-up in place.  

MEAN WELL UHP series UHP-200R, UHP-350R and UHP-500R are single-output power supplies that come with redundant operation when connected in parallel. They are semi-encapsulated with an RTV silicon material for better heat dissipation and improved shock and vibration performance.  

They are not battery chargers nor inverters and will not work with batteries. 

What is Redundant Power Supply? 

Redundant power supply refers to a back-up power system that can supply the same amount of power as the main power source, in case of power outages. This is done by having two power supplies connected through diodes, as shown below.

This setup allows one power supply to take over if the other fails, maintaining a stable connection. Thus, it is important to note that only one system should be used at a time.   

Pro Tip on Installation 

Before we proceed to the installation tip, below are two terms that you first need to understand so you can safely install your redundant operating system. 

Parallel function – refers to connecting multiple power supplies together to produce higher currents while maintaining the same voltage.  

 

For example, there are two channels set to 2V, but each channel can only source up to 10A. When these channels are combined in parallel, it will provide 2V across the load, but can now deliver up to 20A through the load. 

 

Hot-swapping - means you can add, remove, or replace the power supply while the system is still running and powered on. 

 

Now back on point – when using redundant power with parallel function, your setup must have a hot-swapping feature enabled for when the power systems need to switch. This is so you can prevent short circuits caused by damage from the output of power supplies, which may lead to system breakdown.  

When connected in parallel operation, the maximum load should not be greater than the rated power of any power supply unit (PSU).
