Superior Electric 3PN116C Variable Transformer

Superior Electric Powerstat 3PN116C Variable Transformer is a single‑phase, manually adjustable autotransformer (variac) that accepts 120 VAC input and provides an adjustable output up to 140 VAC, with a continuous current rating of 10 A and a 1.2 kVA Powerstat rating. Built with Powerkote‑coated coils for durability, this unit sits in the POWERSTAT family and delivers smooth, knob‑controlled voltage changes ideal for benchtop test rigs, calibration setups, motor control experiments, and electronics lab work where precise voltage adjustment matters. The 3PN116C variant is commonly offered with a cord and plug configuration for convenient use with standard outlets, and it’s documented in distributor and datasheet listings as a 120 V input, 140 V output, 10 A device, with knob rotation providing CW/CCW adjustment.
