Overview
The Acme Electric T181057 buck-boost transformer is a rugged single-phase isolation transformer rated at 0.25 kVA (250 VA). Designed for voltage regulation and low-voltage isolation, this unit steps down from 120×240V AC primary to 16/32V AC secondary. Its encapsulated construction and compact wall-mount design make it ideal for lighting control, low-voltage circuits, and system voltage correction in industrial and commercial environments.
