AERCO Transformers

AERCO Transformers convert line voltage (120 VAC or 240 VAC) to the low-voltage supply needed by control modules, relays, and thermostats in AERCO systems. Engineered for minimal energy loss and long service life, these transformers ensure stable voltage for sensitive electronics. By replacing a faulty transformer with an AERCO unit, service technicians can restore proper control-circuit voltage, eliminate erratic module behavior, and prevent premature component failure.
