Why chokes are used

We are keen to design and manufacture complex chokes. As core materials we use ferrite, powder and amorphous solids. When required, we can incorporate production preferences such as vacuum casting or impregnation as well as special casings. Mains chokes minimise system interference produced by rectifiers.

Mains interference from inverter drives is also suppressed in compliance to EN Top quality is guaranteed through precision processing and the use of high quality materials, e. Output chokes are connected in front of inverters to minimise their negative effects. Voltage spikes from in-line motors are reduced to increase motor service life by diminishing insulation loads.

Line chokes are usually series connected to an electrical load. Single and three phase versions are available. They are intended to provide the following important protective functions:. A large range of toroidal commaon mode chokes is available, all type of material are used and especially nancrystalline material which allow a standard range from 0.

All mountings are available, vertical, horizontal, bare coil, and a new range of SMD power chokes. Electrical VFD. All the semiconductors are having some tolerance to stand high transient current but beyond the limit which leads to semiconductor failure. What is Step potential and Touch Potential and Calculation.

Our range extends from the smallest chip inductors and RFID coils to large air-wound coils for currents up to 1, A. Common mode chokes consist of two coils which are wound on a core.

They can be used to prevent electromagnetic interference EMI and radio frequency interference RFI from power supply lines and to prevent malfunctions in electronic equipment. Chip inductors prevent electromagnetic interference between electrical circuits.

They are extremely reliable and have a high Q value. Chip inductors have many applications such as hands-free units, data communication, computer applications, printers, monitors, gaming machines, digital cameras, video cameras, car electronics and low EMI applications.
