About 1388B-AV20

The 1388B-AV20 servo controller is a controller unit manufactured by Allen-Bradley/Rockwell Automation. These servo controllers are offered in 2 versions: Series A and Series B. As can be seen from the product code and letter “B” added to the series number, this product is a Series B model. All 1388 controllers have a set of standard features and identical mounting equipment and functions. The 1388B-AV20 servo controller also includes features such as logic supply under voltage detection, a tachometer voltage input range of 3 to 135 Volts DC, a shunt regulator and power bus regeneration circuit, an MOV protected input, a line/DB contactor, a complete PMW servo amplifier, RMS armature thermal overload detection, and a dynamic braking resistor.

 

The 1388B-AV20 servo controller has a weight of 10.4 kilograms or 23 pounds and it is designed for industrial environment. The operating temperature range of the unit is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) while the storage temperature should be between 0 and 65 degrees Celsius (32 and 149 degrees Fahrenheit). Like other controllers from the series, the 1388B-AV20 servo controller also has a nominal output voltage of 150 Volts DC. The continuous current of the unit is 20 Amps while its peak current is 50 Amps. In addition to that, the continuous power output and peak power output are 1.5 kilowatts and 7.5 kilowatts, respectively. The 1388B-AV20 servo controller has a minimum circuit inductance rating of 0.5 mH and an internal dynamic braking resistor with a resistance of 1.5 Ohms. The power rating of the internal dynamic braking resistor is 100 Watts. The external shunt resistor of the 1388B-AV20 servo controller has a power capacity of 675 Watts.
