The 1AC4002U is a GP-1200 series three-phase variable-frequency drive from Reliance Electric. It is a first-generation AC drive that accepts 460 VAC input and provides up to 2 HP output to a three-phase motor. Some inventories catalog the unit as 1AC4002U-WN-047. The drive features a blank enclosure and carries UL Listed and CSA approval for use in industrial environments. As a general-purpose VFD, it regulates motor speed by adjusting voltage and frequency, enabling smoother starts, controlled acceleration and deceleration, and energy-efficient operation for small- to mid-size three-phase motors in automation and equipment installations.
