products made in China electrical open type current transformer
Current Transformers
The E-TAL type series for current transformers comprises various versions for a large number of applications. Strong insulation voltage between the primary and the secondary, up to 4kV/1min, without breakdown.
The insulation resistance should be bigger than 1000MΩ between the primary and secondary windings.
Best-performance core designs in close cooperation with our customers.
Technical support including simulation software to optimize the circuit topology.
