MEAN WELL’s Rack Mount Power Supplies Deliver up to 128KW

High Power Rack Mount System

By connecting MEAN WELL’S rack mount power supplies in parallel you have a power solution that can be scaled from 12.8kW to 128kW, making it suitable for different industries and applications.

In fact, MEAN WELL power supplies are currently being used to power a photon source synchrotron.

The synchrotron’s power system supplies DC power for the RF amplifier system, providing ultra-high energy for electrons to be accelerated to near light speed.  

Overview of the Synchrotron 

The following image shows a common ring structure of a synchronous (electron) accelerator. The inner ring is a booster ring, and the outer is a storage ring from which multiple experimental stations branch out.

The ultra-high brightness and wide bandwidth spectrum of light sources (far-infrared to hard X-ray) generated by the synchrotron, make it an indispensable tool for leading-edge fundamental scientific research in the field of biomedical technology and in industrial applications.  

It has contributed to the development of lithium materials achieving longer lasting battery life, which is essential to the development of electric vehicles. It also helps to develop a deeper understanding of nanotechnology, which is a key to the development of semiconductor materials and biomedical products. 

MEAN WELL’s High Power Integrated Rack Mount Power Solution 

The synchrotron uses multiple sets of 96kW high-power power supply systems.

The output from the power system drives the solid-state RF power amplifier clusters.

This generates high-frequency energy for boosting electrons to travel at nearly the speed of light. The maximum DC power output of the whole system is up to 800kW! 

To match the RF power required by the storage ring and for best power efficiency, the output voltage of the power system must be adjustable within a modulation range of 42Vdc to 54Vdc, so that each operating point receives the specific RF power level required to achieve best results.  

The MEAN WELL DRP-3200-48 rack mount power supplies are available with a built in CANBus interface for digital communications, this is used to precisely trim the voltage output.

During experiments, the bus voltage of each set of power systems needs to be adjusted synchronously where they are not connected in parallel. The accuracy of the output power is limited to +/- 1% after trimming. This requires a power supply with digital control. The DRP-3200-48’s CANBus interface allows for the remote control and monitoring of the system via Ethernet. 
 
Another important feature of the DRP-3200-48s is their extremely high efficiency, which is vital for energy savings and environmental protection. An increase of 0.5% in efficiency of every single power supply in an 800kW system, will bring substantial economic savings and environmental benefits over the lifetime of its operation.
