Custom AC Current Sensors
Current Sense Transformers for sensing AC loads are used in numerous applications.
Individual requirements for the power to be sensed and the physical dimensions
of the component often define the final form factor of the part. Most components
in this category have some level of customization.
ZETTLER MAGNETICS offers a variety of solutions for this type of component:
Zero to hundreds of amperes sensed, and frequencies ranging from 50 Hz to 400 Hz. Our solutions to specific custom requirements include the use of conventional material such as lamination, or materials such as iron powder, internally-gapped cores.
A variety of mounting solutions, as well as core geometries, are available.
ZETTLER MAGNETICS offers custom designed inductors for a wide variety of applications from low to high frequencies. Custom designed options use numerous materials, core geometries, and mounting solutions including:
- Horizontal and vertical mount toroids
- EE and U core design chokes
- Air core bobbin wound
- Radial and axial leaded chokes
- Surface mount inductors
- Printed circuit mount inductors
- High voltage inductors
- Shielded ferrite type inductors
