Product Description
The Allen-Bradley 1336 PLUS Sensorless Vector drive is a microprocessor-based adjustable frequency AC drive from the 1336S series. The 1336 PLUS line supports three-phase induction motors and employs pulse width modulation control with programmable carrier frequencies. The series accommodates input voltages of 380 to 480V AC at 50 and 60 Hz, with output frequency ranging from 0 to 400 Hz. Sensorless vector control technology provides speed and torque regulation without the need for external encoder feedback. Physical construction includes a ventilated enclosure with dual rear-mounted cooling fans and a metal mounting bracket base, consistent with a B1/B2 frame configuration in the 15 to 30 HP range. The full catalog number is located on the internal control board mounting plate and was not externally visible at the time of listing; buyers should verify the complete catalog number prior to installation. The 1336 PLUS series is discontinued by Rockwell Automation and is supported by the industrial surplus market.
