Source1 2552314000 460 575V Primary 24V Secondary 150VA Transformer

Product Description

The Source1 2552314000 is a control transformer designed for commercial HVAC systems that operate on high-voltage primary power. This unit accepts a primary voltage of 460 volts or 575 volts and steps it down to a 24-volt secondary output. It carries a 150 VA power rating, making it suitable for powering control circuits in rooftop units, air handling units, heat pumps, and other commercial heating and cooling equipment. Source1 is the genuine OEM parts brand for York, Johnson Controls, and affiliated HVAC product lines. The 2552314000 is a direct replacement for systems originally built with York OEM components, ensuring proper fit and performance without modification. HVAC technicians rely on step-down control transformers like this one to power low-voltage control boards, thermostats, and relay circuits from high-voltage supply lines. In commercial buildings, 460-volt and 575-volt three-phase or single-phase power is common, and the control transformer bridges that high-voltage supply to the 24-volt control circuit that runs the system logic. A failed or undersized transformer can cause erratic system behavior, nuisance tripping, or complete control failure. Replacing with the correct 150 VA rated unit restores reliable control circuit power. The 150 VA capacity provides enough capacity for multiple relay coils and control board loads simultaneously, which is important in larger commercial systems with multiple stages of heating or cooling. Using a genuine Source1 OEM transformer ensures the unit meets original factory specifications for insulation class, thermal protection, and electrical clearances. This part is commonly stocked by HVAC wholesalers and used in preventive maintenance programs as well as emergency service calls.

• Primary voltage rating of 460 volts and 575 volts for compatibility with commercial high-voltage power supplies
• Secondary output of 24 volts to power low-voltage HVAC control circuits, thermostats, and relay boards
• 150 VA power rating supports multiple simultaneous control circuit loads in commercial HVAC equipment
