Transformers
A transformer is a passive electrical device that transfer energy between circuits through electromagnetic induction. Current flowing through one coil in the transformer produces a magnetic field, which induces voltage in a second coil.

Induction between coils allows a transformer to increase or decrease voltage, making transformers essential for power transmission, distribution and utilization in AC power applications.

Transformers are most often used to decrease supply voltage for low voltage circuits. They are also used to isolate equipment from mains power, maintain constant voltage, measure voltage potential, and measure current.

Y65 Series Image
  • Split-bobbin design provides best primary/secondary isolation
  • Multi-tap primaries reduce stocking requirements and offer application flexibility
  • Choice of foot, plate, or conduit hub mounting provides mounting flexibility
  • Meets a wide range of power requirements from 24 VAC through 480 VAC
  • Color-coded lead wires provide simplicity and standardization
The Y63, Y64, Y65, Y66, and Y69 Series Transformers provide 24 VAC power for loads of 40 VA through 300 VA. These transformers are designed for use on digital controllers, gas controls, ignition systems, motor actuators, staging controls, and most other 24 VAC HVAC/R control systems.
