The cased plug‑in models feature a ventilated steel case, input line cord and plug, fused NEMA rated output receptacle, and an illuminated on/off switch. They are connected for output voltage increase with a clockwise rotation, and the dials are graduated from 0‑100% of the voltage setting.
For application flexibility, two field modification kits have been added. The 3PN‑MK kit allows either the 3PN221B or 3PN501B to be wall, bench top, or machine mounted. The 3PN‑SK kit provides an adjustable voltage stop for either the 3PN1000, 3PN1200, or 3PN1500 series. Cased plug‑in models are also available with a pivot and jewel AC voltmeter or ammeter (with ±5% full scale accuracy) conveniently located atop the enclosure for easy readout.
