The Allen-Bradley 1391B-EST45 servo controller is an AC-powered servo controller. This servo controller has an extended speed range which means that it can handle a wider range of applications and motor speeds than regular servo controllers can. Servo controllers like the Allen-Bradley 1391B-EST45 servo controller are made to control industrial motors safely and efficiently. The Allen-Bradley 1391B-EST45 servo controller also has an extended peak torque range in addition to its extended speed range. Its current ratings are 45 Amps of RMS continuous current and 135 Amps of peak current. This servo controller puts out 15 kilowatts of continuous output power and 45 kilowatts of peak output power.
The Allen-Bradley 1391B-EST45 servo controller has an 85% efficiency rating. To ensure that this AC servo controller always operates at full power and as efficiently as possible, always keep the controller properly maintained and install it in industrial environments with the proper ratings. The installation environment should not be more than 3300 feet or 1000 meters above sea level if the controller is going to operate at full power, although the controller can operate at higher altitudes if it is derated. The Allen-Bradley 1391B-EST45 servo controller can operate within a temperature range of 32 to 140 degrees Fahrenheit or 0 to 60 degrees Celsius. It can be stored within a temperature range of 32 to 149 degrees Fahrenheit or 0 to 65 degrees Celsius. The servo controller should be used and stored in an environment that is dry or that has a non-condensing relative humidity level between 5 and 95%.
