Source1 2547239000 Hvac Control Transformer 208 240V to 24V 100VA 60hz

Product Description

The Source1 2547239000 is a control transformer designed for HVAC systems that require a reliable step-down voltage conversion. It converts primary input voltages of 208 or 240 volts down to a 24-volt secondary output, which is the standard control voltage used across a wide range of heating, cooling, and air handling equipment. The unit is rated at 100 VA, giving it enough capacity to power the control circuits found in most residential and light commercial HVAC applications. It operates at 60 Hz, making it fully compatible with standard North American electrical systems.

Control transformers like the Source1 2547239000 are a core component in HVAC electrical systems. They power the low-voltage side of the control circuit, which includes thermostats, contactor coils, relay coils, and safety switches. Without a properly functioning transformer, the control system cannot send signals to start or stop the compressor, blower motor, or other equipment. When an HVAC technician diagnoses a system that fails to respond to thermostat commands, a failed control transformer is one of the first components to check. This unit is a dependable replacement option that fits common wiring configurations used by major equipment manufacturers.

The dual primary voltage rating of 208 and 240 volts gives this transformer added flexibility. It can be wired for either voltage depending on what the local supply circuit provides. This is particularly useful in commercial settings where 208-volt three-phase power is common. The 24-volt secondary output and 100 VA capacity align with industry-standard requirements, making this a straightforward drop-in replacement for service technicians. Proper installation requires matching the primary tap to the supply voltage and ensuring the secondary load does not exceed the transformer rating.

• Step-down transformer converts 208V or 240V primary input to 24V secondary output for HVAC control circuits
• 100 VA rating supports thermostats, contactor coils, relay coils, and other low-voltage control loads
• 60 Hz operation is compatible with standard North American residential and commercial HVAC systems

Product Highlights

The Source1 2547239000 control transformer provides reliable 24-volt power for HVAC control circuits from 208 or 240-volt supply lines. Its 100 VA capacity and 60 Hz rating make it a dependable replacement for residential and light commercial heating and cooling systems.
