AC Tech Q14100B Industrial Variable Speed Drive

The AC Tech Q14100B is a 100 HP (75 kW) industrial variable speed drive (VFD) designed to control three‑phase motors from a 400–480 VAC power source. This unit is part of AC Tech’s Q‑series family and accepts 50/60 Hz input to provide a variable‑frequency, variable‑voltage output that can drive AC motors rated up to about 460 VAC. The model supports standard three‑phase motor control in industrial environments, enabling smooth start/stop, adjustable speed, and energy‑efficient operation for varying loads. Some configurations of the Q14100B are offered with an MCH BYPASS option, which provides a dedicated bypass path for service or fault conditions without removing power from the motor. With a 100 HP rating at 480 VAC, the drive is intended for medium‑horsepower industrial installations and can integrate with typical motor control panels and automation systems for applications requiring precise speed control and reliable performance.
