TRNSFMR 40VA 120/208/240

🔧 What it’s used for:

• HVAC systems (furnaces, air handlers, AC units)
• Thermostats and zone controls
• Relays and contactors
• Boiler and hydronic control circuits

⚙️ Why it matters:

Most residential and commercial control systems run on 24V low voltage, so this transformer:

• Supplies safe control voltage
• Isolates control circuits from high voltage
• Ensures consistent operation of HVAC controls

🧠 Simple explanation:

It’s basically a power converter for HVAC systems that takes normal house voltage and steps it down to 24V so thermostats and controls can safely run.
