Product Details:

Allen-Bradley 1336-B003-EAD-L3-S1 belongs to Rockwell Automation Bulletin 1336 PLUS II series adjustable frequency AC drive, it is a discontinued 3HP (2.2kW) three-phase inverter unit equipped with L3 power line filter and S1 encoder feedback option. This variable frequency drive adopts microprocessor digital control and PWM pulse width modulation technology, rated three-phase input voltage 380/415/460VAC three-phase, rated output current 6A, designed for closed-loop speed and torque regulation of industrial three-phase induction motors. The L3 power line filter suppresses grid electromagnetic interference and harmonic distortion; S1 encoder option supports encoder signal feedback to realize high-precision closed-loop motor speed control.

This 1336-B003-EAD-L3-S1 supports flexible parameter configuration, built-in multiple motor control algorithms and comprehensive fault diagnosis functions. It reserves analog 0-10V and 4-20mA interfaces for remote speed setting, compatible with local HIM operator panel and SCANport communication adapters for parameter configuration and real-time operating data monitoring. The whole unit adopts NEMA Type 1 IP20 cabinet panel mounting structure, complies with UL and CSA industrial certification standards. It is widely used for spare replacement and maintenance retrofit of legacy industrial production lines including conveyors, pumps, fans and packaging machinery requiring precise speed control.

Each Allen-Bradley 1336-B003-EAD-L3-S1 undergoes strict factory testing before shipment, including power-on running test, insulation resistance test and protection function verification to ensure stable performance in industrial automation environments.
