Trane TRR2736 Transformer 120V Primary 24V Secondary 35VA

The Trane TRR2736 is a transformer that is manufactured to be used by and only for the HVAC all-in-one equipment. It transforms the normal source of power in people’s homes today (120V) to a lower voltage of 24V. This is less dangerous and ideal to handle in powering a variety of control circuits and parts of your HVAC system. In other words, the transformer is similar to a voltage converter. Try to fit a phone charger that is created for 120 V into a car that operates at a 12 V system. This transformer steps down the voltage to avoid placing a lot of load and pressure on the charger.
