Y63, Y64, Y65, Y66, and Y69 Series Transformers
Code No. LIT-1922175
Y65 Series Transformer
Description
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.
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).
Refer to the Series Y63, Y64, Y65, Y66, and
Y69 Transformers Product Bulletin
(LIT-125755) for important product application
information.
Features
• 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
Repair Information
Do not make any field repairs to transformers.
For a replacement transformer, contact the
nearest Johnson Controls® distributor or
sales representative.
