The Allen-Bradley 1336S-BRF20-AE-EN4-L4 drive is a 2 Horsepower rated 1336S PLUS variable-frequency drive. Drives from the 1336S PLUS series support the advanced sensorless vector algorithm for motor control and they offer output power ratings ranging from a minimum of 0.37 kilowatts to a maximum of 448 kilowatts. The output power rating of the 1336S-BRF20-AE-EN4-L4 drive is 2 Horsepower or 1.5 kilowatts. The input voltages supported by the drive are 380 to 480 Volts AC or 513 to 620 Volts DC. Input protection is enabled on the drive with the drive programmed to trip at 570 Volts AC and at 280 Volts AC, which are the respective high-voltage and low-voltage thresholds. Voltage protection is also enabled on the drive bus. The high-voltage and low-voltage thresholds for the drive bus are 810 Volts DC and 400 Volts DC.

The input current ratings for the 1336S-BRF20-AE-EN4-L4 drive are 4.6 Amps and 4.8 Amps for constant and variable torque, respectively. The output current ratings are 3.8 Amps and 4 Amps for constant and variable torque operation, respectively. English is the language supported by the drive-mounted language module. Control I/O on the 1336S-BRF20-AE-EN4-L4 drive are compatible with the TTL contact. The 1336S-BRF20-AE-EN4-L4 drive is available in an IP 20 (NEMA) or EMC rated enclosure with an A2 type of frame and it weighs 12.1 pounds. The dimensions of the drive frame are 290 x 215 x 180.5 millimeters. The 1336S-BRF20-AE-EN4-L4 is engineered for use with 3-phase electrical systems with symmetrical line voltages. The drive incorporates surge suppression for protection against high voltages between the line and ground which could occur because of lightning. Isolation should be provided for systems with a high probability of line to ground voltages.
