1336S-BRF10-AN-EN4-L6

The 1336S-BRF10-AN-EN4-L6, a variable frequency drive from Allen Bradley's 1336 PLUS Drives series, provides reliable control over motor functions. This drive specifically supports a voltage rating between 380–480 VAC while also catering for DC applications ranging from 513 to 620 V. It is equipped to handle nominal motor power ratings of 0.75 kW, which is equivalent to roughly 1 horsepower. In terms of control, the unit operates with a control interface of 115 V AC.

Under constant torque conditions, the drive manages an input of 1.7 to 2.1 kVA, drawing 2.6 Amps, while the output reflects similar capabilities with a 1.7 kVA output and 2.1 Amps. For variable torque scenarios, it operates with input levels ranging from 1.8 to 2.2 kVA and 2.8 Amps, ensuring an output of 1.8 kVA and 2.3 Amps to meet dynamic load requirements.

This unit is designed to operate with three-phase power systems; however, it can handle single-phase inputs at a 50% derate. The frequency tolerance ranges from 48 to 62 Hz, accommodating common industrial applications. Power factor variations are substantial, achieving a rating of 0.80 for phases A1 to A3 and 0.95 for phase A4 and above. Featuring an impressive efficiency rating of 97.50%, the 1336S-BRF10-AN-EN4-L6 stands out for reducing energy losses.

Moreover, the drive has a significant short circuit rating of 200 kA rms at 600 V, which adds an extra layer of protection and ensures the device remains operational under fault conditions. Employing a sine-coded PWM control method allows for smooth operation across a range of output frequencies up to 400 Hz, making it suitable for precise motor control applications.
