The Allen Bradley 1336F-C125-AN-EN-L6 is a sophisticated variable frequency AC drive tailored to enhance the performance of three-phase systems by operating within an input voltage range of 500 to 600 VAC. It is proficient in delivering a continuous power output of 93 kW, accommodating constant torque and variable torque motor capacities at 125 HP, equivalent to NEMA Design B efficiency specifications.
Regarding current rating, this model handles a full-load current of 138 Amps when functioning in constant torque or variable torque modes at the designated voltage.
The drive incorporates several critical safety features to protect against potential electrical faults. It has an automatic trip mechanism that activates at 690 VAC for AC overvoltage conditions, while an undervoltage threshold triggers a shutdown when the input drops below 343 VAC. The DC bus is equally safeguarded with fault detection that initiates at 1013 VDC for overvoltage situations and activates protection at voltages below 498 VDC. Normal operating conditions maintain a nominal DC link voltage of 810 VDC.
Furthermore, the 1336F-C125-AN-EN-L6 includes multi-stage overcurrent safeguards. The software limit is adjustable between 20% and 160%, and a hardware cutoff engages at currents from 180% to 250% of rated values. The drive's open chassis design is rated IP00, signifying that it lacks environmental sealing, suggesting its suitability for clean, controlled environments. For control signal interfacing, it utilizes a 115 VAC standard interface to manage logic inputs and outputs.
