Variable Transformer 15A (1500VA) | 0–130VAC Benchtop Variac with LCD Voltmeter | SC-15M

1500VA Heavy-Duty Variable Autotransformer (15 Amp) | Model SC-15M

The SC-15M is a high-performance 1500VA variable autotransformer designed for precise AC voltage adjustment on standard 120V industrial, laboratory, and workshop circuits. Delivering a smooth, adjustable output from 0 to 130VAC at up to 15 Amps continuous duty, the SC-15M maxes out standard 15A branch circuits without requiring expensive 20A dedicated lines.

Why Choose the SC-15M?

• Optimized for Standard 15A Outlets: Provides maximum continuous power draw (1500VA) permissible on standard NEMA 5-15 wall receptacles—ideal for motor speed testing, heating elements, and industrial equipment development.
• Real-Time LCD Monitoring: Features a high-visibility digital LCD voltmeter to eliminate guess-and-check dial adjustments and protect sensitive equipment from over-voltage.
• Rugged & Circuit-Protected: Heavy-duty ventilated steel enclosure equipped with dual AC output receptacles, lighted power switch, and quick-replace overload fuse protection.
