The 1388B-AV-20-D from Allen Bradley stands out as a robust servo controller that excels in managing DC servo control applications. Weighing 21 lbs, this unit is designed for installation within a control cabinet or mounted on a panel, ensuring efficient utilization of space. Cooling is facilitated through natural convection, which supports heat dissipation without additional fans or components.

This controller operates with an output voltage of 150V DC, delivering a continuous current of up to 20 Amps. For brief periods, it is capable of handling a peak output current of 50 Amps, accommodating high-demand applications. It provides reliable performance with a continuous power output of 1.5 kW, while achieving a peak power capacity of 7.5 kW, making it suitable for diverse servo motor requirements.

Input specifications detail a nominal voltage of 120 VAC, with support for three-phase input, functioning effectively across both 50 and 60 Hz input frequencies. The minimum circuit inductance specified is 0.5 mH, which is crucial for stable operation, and the system incorporates a 15 Ω internal shunt resistor to enhance performance and reliability in managing electrical loads.
