Series CNE
Single-phase encapsulated isolating transformer
Series CNE
Single-phase encapsulated isolating transformer
With galvanic isolation between primary and secondary, the CNE series has excellent attenuation against electrical disturbances.
The windings are fully protected against shocks, dust, dirt and humidity in adverse saline or corrosive environments. Increases the mechanical resistance to electrodynamic winding stresses, extending the life of the insulation. Improves reliability when working in vibrating environments.
Features
- Winding completely protected against shocks, dust, dirt and humidity.
- Transparent cover to protect the connection terminals to avoid the risk of accident due to electrical contact.
- Built-in lifting eyelets or eyebolts.
- Low-loss magnetic core impregnated with anti-rust epoxy varnish.
- Improved reliability when working in vibrating environments.

Uses
For general use as galvanic isolation between mains and load.
For generating a single-phase neutral independent of the mains free from common-mode electrical disturbances.
In two-phase systems to generate a single-phase system with TN-S or TN-C neutral, depending on the type of installation, it requires additional residual current circuit breaker protection.
For isolated two-phase IT systems, additional insulation monitoring protection is required.
