ELETRAS: Industrial Control Transformers, Line Reactors & Voltage Stabilizers

International industrial catalog of ELETRAS (Italy): single-phase and three-phase control transformers compliant with CEI EN 61558, potted EL series PCB transformers, line reactors, smoothing chokes, and industrial voltage stabilizers.

Single-Phase and Three-Phase Control Transformers CEI EN 61558

Eletras single-phase and three-phase transformers rated up to 500 kVA meet CEI EN 61558 and UL/CSA standards. The units provide galvanic isolation, control power, and machinery protection. Vacuum varnish impregnation and touch-proof IP20 terminals ensure reliable insulation.

  • Power ratings from 20 VA up to 500 kVA for single and 3-phase grids
  • Full compliance with CEI EN 61558 standards and UL/CSA approvals
  • Electrolytic copper and aluminum windings with vacuum varnish
  • Finger-safe screw terminal blocks with IP20 touch protection

Resin-Encapsulated Transformers for PCB and DIN-Rail Mounting

Eletras EL series transformers are potted with self-extinguishing epoxy resin in UL94-V0 cases. Designed for through-hole PCB and DIN-rail mounting in railway signaling and automation. Solid encapsulation prevents moisture ingress, dust penetration, and vibration damage.

  • Vacuum potted with self-extinguishing epoxy resin to UL94-V0
  • Through-hole PCB pin mounting and standard DIN-rail clip options
  • Dielectric insulation test voltage up to 4 kV between windings
  • High vibration and shock endurance meeting railway regulations

Line Reactors, Smoothing Chokes and Industrial Autotransformers

Eletras line and motor reactors safeguard variable frequency drives and attenuate harmonic distortion in industrial power grids. Gapped-core smoothing inductors stabilize DC currents in rectifier circuits. Compact autotransformers achieve economical voltage matching with low magnetic losses.

  • Precision inductance engineered for continuous currents up to 1000 A
  • Effective attenuation of line harmonics THD and peak switching surges
  • Low-loss grain-oriented silicon steel cores with air-gap design
  • Natural convection air cooling with heavy-duty mounting brackets

Electromechanical Voltage Stabilizers, Industrial Rectifiers and UPS

Eletras voltage stabilizers regulate unstable factory grids with high precision within ±1%. Industrial rectifiers and uninterruptible power supplies supply filtered DC power to critical loads. The assemblies integrate manual maintenance bypass switches and thermal winding protection probes.

  • Tight output voltage stabilization accuracy within ±1% tolerance
  • Electromechanical servo-drive and solid-state electronic switching
  • Integrated manual and automatic bypass for maintenance continuity
  • Overload, short-circuit, and embedded thermal winding protection

Integration of ELETRAS Transformers and Inductors into Industrial Cabinets

ELETRAS industrial control and isolating transformers operate across machine tools, packaging automation, and transport systems worldwide. Galvanic isolation eliminates common-mode ground interference and shields sensitive computer numerical control electronics from line surges.

During switchboard retrofits, electrical designers calculate peak inrush currents from contactor coils to determine optimal transformer VA ratings.
