Resideo AT120A1004 Transformer 120/208/240V-PRI 24V-SEC 20VA

The Resideo AT120A1004 Transformer is used to reduce electrical voltage for use in different HVAC systems. It operates by taking in primary voltage of 120/208/240V and produces a secondary voltage of 24V with a power of 20VA. In the working process, power is received at the higher primary voltage and transformed to a lower secondary voltage suitable for HVAC control circuits. This makes it possible to have durable operations of systems like thermostats, relays and air conditioning units. The advantages include increased efficiency in the use of energy, less strain on the HVAC parts, and a constant supply of power that is used in increasing the longevity of the system.
