Description
When your HVAC control circuits need a stable low‑voltage supply, the YORK S1‑025‑18452‑700 transformer delivers reliable performance and safety — ideal for replacing worn or failing control transformers in furnaces, air conditioners, and heat‑pump units.
Key Features
- Primary 208–240 V / Secondary 24 V (40 VA) — converts high‑voltage main power down to safe 24 V for thermostats, relays, control boards, and other low‑voltage HVAC components.
- OEM‑grade quality — built by York to meet original equipment specifications, ensuring proper fit, reliable voltage output, and long service life in compatible York HVAC systems.
- Foot‑mount design — compact, sturdy and simple to install in existing control boxes or mounting brackets — ideal for retrofit or replacement jobs.
- Essential for safe control circuitry — without a functioning 24 V transformer, thermostats, relays, and control modules can’t operate safely — replacing this transformer restores proper system control and safety.
