Overview

The Dart Controls 57AC15E (SKU: 57AC15E) is a compact, enclosed triac-based variable AC voltage supply designed for single-phase motor speed control in industrial applications. This 240VAC, 15A unit delivers fully variable AC output to regulate speed for shaded pole, permanent split capacitor (PSC), permanent split-phase (PSP), universal motors, or resistive loads. The rugged NEMA 4 housing includes a power on/off switch, indicator lamp, front-access fuse, and input/output cords with plugs for plug-and-play installation. The triac firing circuit adjusts phase angle to vary output voltage, enabling precise speed control without complex wiring. Ideal for vibratory feeders, fans, pumps, heating systems, and lighting, the 57AC15E eliminates the need for capacitor-start motors, which are incompatible with triac controls. Its enclosed design ensures protection against dust and moisture while providing easy access for maintenance. Compatible with fractional HP motors up to 1/3 HP at 240VAC, this control is a cost-effective solution for OEMs and end-users requiring reliable, adjustable AC motor speed control in compact spaces.
