York S1-025-49714-000 Transformer

The York S1-025-49714-000 Transformer is a heavy-duty 460V to 24V transformer specifically engineered for industrial and commercial HVACR applications. This 75VA control transformer provides the necessary power delivery for low-voltage control circuits, including contactors, relays, and diagnostic boards found in York rooftop units and chillers. Designed as a foot mount control transformer, it allows for secure, vibration-resistant mounting within electrical cabinets. This unit serves as the direct replacement for S1-025-25974-700, ensuring that contractors can maintain original equipment specifications without requiring field modifications or auxiliary mounting hardware. When navigating high-voltage systems, maintaining stable 24V secondary output is critical for the longevity of sensitive control components. This York replacement part is built to handle the thermal demands of continuous operation, effectively stepping down 460V primary line voltage to the 24V secondary required for modern HVACR control logic. Its robust construction minimizes electromagnetic interference, ensuring a clean signal for equipment automation.
