Trane TRR1873 Transformer 120V 3A 375Va

The Trane TRR1873 is an automatic transformer for HVAC applications only. It is safe and reliable in terms of modifying the incoming voltage level to a level appropriate to the connected devices. They also play a role of a ‘go-between’ which helps to regulate a 120V AC voltage supply to the HVAC unit in order to enable it to work as expected. Automatic transformers are especially desirable in the case of a fluctuating or incompatible incoming voltage to the HVAC system. Thus, the transformer facilitates a proper supply of voltage to the HVAC equipment to enable it to work more efficiently and competently.
