Acme TF-2-17437-S Single-Phase Buck-Boost Transformer TF Series

Product Description

Overview

The Acme TF-2-17437-S is a high-quality single-phase dry-type buck-boost transformer, designed to provide precise voltage adjustment for commercial, industrial, and light-duty electrical equipment. Engineered for indoor and outdoor use, this transformer ensures stable operation where line voltages slightly deviate from nominal ratings. Its compact design, weatherproof NEMA 3R enclosure, and wall-mount capability simplify installation in both retrofit and new electrical systems.

Key Features

• Voltage Adjustment: Capable of both boosting and reducing line voltage to match equipment specifications

• Compact and Efficient: Smaller and more energy-efficient than equivalent isolation transformers due to partial load transformation

• Rugged Construction: Encapsulated core and coils with electrostatic shielding minimize noise and vibration

• Wide Voltage Range: Multi-tap primary allows operation across 190–440 VAC

• Weatherproof Enclosure: NEMA 3R-rated for indoor/outdoor installation

• Thermal Management: Class H insulation supports safe operation at 115°C temperature rise

• Quiet Operation: Encapsulation reduces operational hum, suitable for commercial and institutional settings

Technical Specifications

Applications

• Commercial and industrial lighting systems where supply voltage differs from equipment rating

• Air conditioning units, motors, and pumps requiring precise voltage correction

• Retrofit electrical installations in commercial buildings

• Small machinery and electronic devices sensitive to under- or over-voltage conditions
