Client
For a number of decades, the company JEMA (also known under the name JEMA Elec) has been the uncontested Belgian specialist in high performance DC power supplies while remaining a benchmark in the production of made to measure coil-based dry and resistance transformers. JEMA's high performance DC power supplies contribute daily to the treatment of hundreds of patients in numerous proton therapy treatment centres (cancer treatment by proton beams) in Europe, Asia and the United States.
Project
In the scope of the proton therapy treatment, JEMA has to develop a very high performance DC power supply. This power supply is involved in the proton beam control and has thus very strong requirements.
Challenge(s)
The stability requirements on the supply output are far beyond the existing DC supplies existing in the market (10mA of precision on a 160A current output). The high power sections have to be integrated in the same package than the fully digital control.
Beside these technical requirements, a strict cost control is asked to DELTATEC within a very thigh schedule.
Solution
To accelerate the development process, DELTATEC designed a system utilizing a standard power supply (off the shelf). However, this power supply did not fully meet the required performance standards.
Therefore, DELTATEC integrated a regulation/calibration and management system, all within a 19-inch rack.
In just 3 months, the system was delivered, meeting expectations perfectly. DELTATEC then took over the production of the system.
