Johnson Controls Series Y63, Y64, Y65, Y66, and Y69 Transformers

Series Y63, Y64, Y65, Y66, and Y69

The Series Y63, Y64, Y65, Y66, and Y69 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 Heating, Ventilation, Air Conditioning, and Refrigeration (HVACR) control systems.

The Y6x Series meets the requirements of UL 1585, UL 506, and CSA C22.2 No. 66, providing compliance in both the United States and Canada. The Y63, Y64, Y65, and Y66 transformers are listed as Class 2 transformers (UL 1585, CSA C22.2 No. 66). The Y69 is listed as a general purpose transformer (UL 506, CSA C22.2 No. 66).

• 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
• choice of primary voltages—meets a wide range of power requirements from 24 VAC through 480 VAC
• color-coded lead wires—provide simplicity and standardization
• cULus listed or cURus recognized—meets US and Canadian requirements for Class 2 transformers (Y63, Y64, Y65, and Y66) and general purpose transformers (Y69)
• built-in, easy-reset circuit breakers— eliminate replacement time and cost caused by burn-out (Y63, Y64, Y66, and Y69)
• open frame Y65 models—serve as ideal models when end bells are not required
