The Allen Bradley 1336F-BRF10-AJ-DE is specified as an adjustable frequency drive suitable for three-phase systems. Its voltage input can range from 380 to 480V AC. It is designed to support various torque loads and delivers continuous torque at 0.75 kW (1 HP) with an output current of 2.1 A. In the case of variable torque applications, it optimizes operation at an output current of 2.3 A while sustaining the same power rating.
Protection features include overvoltage and undervoltage trip levels set at 570V AC and 280V AC, respectively. The nominal DC bus voltage under standard conditions is 648V DC. Operational performance is robust, with an impressive efficiency rating of 97.5% at the rated current and voltage.
The control methodology used is a sine-coded PWM that allows adjustment of the carrier frequency, which can vary between 2 and 8 kHz. The communication capabilities of this drive include support for DeviceNetâ„¢, Remote I/O, and RS232/422/485 interfaces, enabling versatile connectivity options.
Built to withstand industrial environments, its enclosure conforms to NEMA Type 12 / IP54 standards, which ensures resistance to dust and other particulates. When enclosed, this unit's operational temperature range spans from 0°C to 40°C (32°F to 104°F), making it suitable for various installation conditions. This drive enhances control and flexibility for precise motor management in demanding applications.
