Performance:
The CLF series generators provide stable process power up to 5 kW. The half-rack supplies operate at any fixed frequency from 20 to 50 kHz. The full- rack models can operate at any fixed frequency from 20 to 450 kHz or auto-tuned up to +/- 15% bandwidth. In many applications, the combination of auto-tune and excess power headroom will allow delivery of power to changing reactive loads without the need for mechanically tuned matching networks.
Applications:
The CLF series is designed to meet the performance demand in RF-driven plasma systems for semiconductor processing. Applications include etch, RIE, parallel plate, ICP, RF sputtering, CVD and PVD, as well as induction and dielectric heating processes in industrial systems. |

Looking into the future!
Finland, Jyvaskala January 2006 Jean Mueller launched their new IP20 protected L-shaped busbar system for the Scandinavian market. This system was especially designed for the Jean Mueller, vertical SL-fuse switch disconnector cassette system to protect people from touching the live copper bars. Next to their already existing busbar solution with flat copper bars this completes the ranges for the Scandinavian market. The question now rises if there is an enclosure solution which can handle both busbar systems into one solution?
The Eldon answer for the ABB and Jean Muller Vertical cassettes
In close co-operation with both ABB and Jean Mueller, Eldon has developed a ready to use market solution for both types of cassettes. The SL-fuse disconnector of JM and the InLine cassette of ABB. The new enclosure type is called MCBAxxxxV for Vertical mounting of the units. Customers who are buying the Eldon Multi-Flex® solution can decide either to build-in the IP20 protected busbar system or the standards flat copper busbar solution. Both will fit.

Work stations
Work stations facilitate the provision of tools, small parts, testing devices etc. directly at the workplace. Their modular structure ensures individual solutions to meet specific
requirements in respect of ergonomics, productivity and operating convenience.
Tool holders
Like work stations, tool holders permit the convenient arrangement of tools and small parts directly at the workplace. Their modular construction ensures individual
solutions to meet specific requirements in respect of ergonomics, productivity and operating convenience.
Energy carrier system
Using the energy carrier system a defined working area of 3 to 18 metres can be continuously supplied with energy (compressed air and/or electricity). The energy is supplied by means of the air hose inserted in the energy chain and/or a power cable.
Data lines can also be integrated. The energy is supplied through fixed tapping stations.
For energy carrier systems rails without tapping valves or connection plates are normally used.
They can be coupled with work stations, tool holders and tool carriages. |

The usual practice for reactive energy correction in industrial electrical systems, consists in connecting capacitors, some times fixed or generally controlled using automatic power factor regulators. However, directly connecting capacitors to the system is not always possible for several reasons, such as:
The existence of harmonic currents, generated by non lineal loads.
The possibility of resonance between capacitors and certain inductive loads or even the reactive dispersion of the supply transformer.
Generation of microcuts or other disturbances in the voltage at the time of connecting the capacitors, if the system's short circuit power is insufficient.
Lessening high frequency command signals transmitted through the system.
It is necessary to add reactances for each of these cases, sometimes to filter disturbances or others to obtain an appropriate rejection of harmonics or high frequency signals and to meet international standards on these events.
CIRCUTOR has developed a complete manufacturing program for power filters to correct the following problems:
Correcting resonance problems
Harmonic rejection in certain parts of the installation
Absorption of harmonics to reduce THD in the installation

Single-Phase EMI/EMC Filter
Single-phase filters for chassis or DIN-rail mounting are key for EMC compliance of higher power office equipment and low to medium power industrial applications. A broad selection of electrical and mechanical features allows a specific choice and deployment for countless applications. |
|
Three-phase and neutral line filters are a compact solution for the interference suppression on the mains input of cabinets and control units of equipment, ranging from industrial applications like machine tools to sensitive medical installations. These typically involve separate and often
insufficiently filtered frequency inverters and SMPS, causing current imbalance and significant interference problems. As individual elements they may be interference-suppressed already. The conjunction of several switching components in the same cabinet and a non-EMC conscious cabling will rise the demand for an additional EMC filter on the mains input of the whole installation. Many times this is the only way to get the CE mark for the cabinet in accordance with the EMC directive. |
