Carrier HT01AH857 Transformer 240/480V PRI 120/240V SEC 100VA

The Carrier HT01AH857 is a 100 VA transformer that is used with Carrier HVAC equipment only. It is the regulator of voltage in your system. It works by rectifying the incoming primary voltage, which could either be 240V or 480V, to a secondary voltage that can be used, 120V or 240V. Its flexibility to operate on dual voltage on both the primary and secondary sides makes the HT01AH857 suitable for different uses in carrier HVAC systems. This transformer controls voltage well to ensure that your HVAC equipment gets the right power it needs to run and not overpower it.
