Closed Loop Current Sensors
Closed-loop current sensors with VAC-invented magnetic probe as zero field detector for highest accuracy. VAC current sensors cover three orders of magnitude of rated current between 1.5 A and 1,700 A.
Nanocrystalline Common Mode Chokes
Common mode chokes (CMCs) based on nanocrystalline VITROPERM® offer highest attenuation in compact designs for a wide range of EMI requirements. The broad portfolio of standard types offers solutions for 1-phase and 3-phase applications as well as 4-fold CMCs.
Differential Current Sensors
Closed-loop differential current sensors with VAC-invented magnetic probe for highest accuracy. VAC differential current (DI) sensors cover differential currents from 30 mA up to several Amps.
Amorphous and Nanocrystalline Cores
Tape-wound toroidal and oval cores made of nanocrystalline VITROPERM® or amorphous VITROVAC® offering low losses over the full permeability range between µ~3,000 to µ>100,000.
Current transformers for 50 Hz/60 Hz energy meters require core materials with highest permeability and linearity.
