The Allen-Bradley 1391B-ESAA45 servo controller is expertly crafted for precise control of single-axis servo motors within closed-loop systems, representing the high-quality standards of the 1391B series. Featuring an open frame with a protective front cover, this controller offers seamless panel installation and optimal ventilation through an enclosure. Key attributes include transient input protection, an integral circuit breaker safeguarding all three AC lines, and a shunt regulator for effective energy dissipation during regenerative braking. With a speed of 300 Volts DC and 90 Amps current rating, it's ideal for clean environments, though attention must be given to heat-sensitive cabling due to potential high temperatures around the unit.
