Description
The MARS 44517 Transformer 120/208/24024V 40VA is a step-down control used to convert higher line voltage into low-voltage power for circuits. It works by electromagnetic induction, reducing input to a stable capacity for safe operation of thermostats, relays, and control boards. It is mounted inside the control compartment and wired into the electrical supply and secondary control circuit. The unit ensures consistent control voltage delivery, supports system switching, and supports maintaining stable operation of low-voltage components during continuous heating and cooling cycles in HVAC systems such as furnaces, air handlers, and refrigeration units.
