Flexibility on the next level: Heinzinger Magnet Power Supplies

Presse |   Presse

Heinzinger has achieved the next level of flexibility in Magnet Power Supply (MPS) technology and design: Power-Stages for MPS, which are flexible and configurable to nearly each customer requirement.

Many customer requests and tender-processes show, that performance of MPS is similar, but never copyable or coverable by standard devices without any customer specific adaptation. Each application is challenging and has its own needs. To act as flexible and short-term as the dynamic market request is, Heinzinger built up a kit of MPS power-stages, which can be connected in parallel as easy as possible.

The basis covers standard parameters, which are explored and proved over many years: e.g. precision up to 1*10-5, current ramping of 300A/second, water-cooling, Ethernet IF for remote- and local operation, minimized overshoot and ripple, etc.

Hereby, the most important customer benefits are ensured:

Flexibility, cost-efficiency, short-term availability and highest reliability.

The power-stages can be combined in one 19” standard-rack, where up to 12 devices can be installed. Each power-stage is able to cover 7.5 kW, thus nearly 100kW can be reached within one rack. Central water-distribution, analog instruments, central customer IF for magnet-read back-signals and auxiliary-input, local operation -> all these features are developed and installed during many years of close partnerships with customers e.g. in accelerator business and their magnet applications.

The MPS are according to IEC 61010 and could be covered by a CB-certificate if necessary. EMC-standards could be applied in case of and confirmed by an external laboratory. 

Typical magnets which are supplied are Quadrupole and Dipole MPS: precise output currents up to 1500A are representative and one of the targets which must be achieved.

Heinzinger has supported well known customers in magnet power applications over many years. Those are located all over the world and mainly in accelerator business for patient-treatment with protons (e.g. Varian Medical Systems) or in particle research and development (GSI, Cern, etc.).
