Electromagnetic control components demand inrush currents up to 10 times the transformer's nominal rating without sacrificing secondary voltage stability beyond practical limits. International Series transformers fully comply with IEC and NEMA standards and are available with IEC touchproof covers (IP20).
International Series Control Transformer Features
- cULus, CE, RoHS
- Epoxy encapsulated for cooler operation
- Interleaved copper windings to reduce impedance
- 50/60 Hz +55°C Rise
- +105C insulation system for harsh, heavy duty applications
- Exceeds IEC, NEMA, ANSI, NMTBA, JIC and automotive standards
