The STACO 3PN1510 is a single-phase variable transformer (Variac) that delivers adjustable AC voltage output from 0–140 VAC with smooth, continuous control. Rated at 2.1 kVA (2100 VA) and 15 A maximum load current, this unit accepts 120 VAC, 50/60 Hz input and provides precision voltage regulation essential for equipment testing, commissioning, and experimental work. The transformer is housed in a ventilated steel enclosure and arrives pre-corded with a NEMA 5-15P plug and 6 ft line cord. Output connects via a fused NEMA 5-15R receptacle. Manual control via knob rotation (clockwise increases voltage) offers 0–100% dial graduation. An illuminated on/off switch provides convenient operation. Benchtop-configured as standard; optional mounting kits (sold separately) support wall or machine installation. Select model variants include integrated analog metering—the 3PN1510BV includes an AC voltmeter with ±5% full-scale accuracy.
