Trane TRR0579 87VA Transformer 460-600V PRI/24V SEC

The Trane TRR0579 is a transformer whose purpose is for use in HVAC equipment. This device in this case changes the voltage of electricity from higher 460/600 volts to lower 24 volts. This is necessary because many control components in HVAC systems run at low voltage for safety and efficiency reasons. Laws of electromagnetic are used to transfer electrical energy from wire coils to wire coils utilizing a transformer. This particular transformer and has a footprint of about 4.5", which is a relatively small thing. The foot mounting style for safe installation in HVAC systems.
