1391-DES45-DI-AQB-A

The Allen-Bradley 1391-DES45-DI-AQB-A servo drive is an AC-powered digital servo drive has an M-contactor coil voltage rating of 24 Volts DC and a nominal bus voltage rating of 300 Volts DC. It weighs about 34 pounds, its power factor rating is 95% minimum, and its efficiency rating is 85% minimum with a rated load. The Allen-Bradley 1391-DES45-DI-AQB-A servo drive operates best at a maximum altitude of 3300 feet above sea level in a temperature range of 32 to 140 degrees Fahrenheit. When it is not in use, this digital servo drive can be stored in a temperature range of 32 to 149 degrees Fahrenheit. In storage and in operation, the Allen-Bradley 1391-DES45-DI-AQB-A servo drive should be kept away from corrosive substances and high levels of moisture. It is made for dry environments or environments with non-condensing relative humidity at a level between 5 and 95%.

The Allen-Bradley 1391-DES45-DI-AQB-A servo drive is protected from damage by built-in circuit breakers with an input circuit breaker trip rating of 38 Amps RMS and a circuit breaker interrupt trip rating of 1300 symmetrical Amps. This servo drive should be mounted in an enclosure for protection, and this enclosure should have a ventilation system that uses cool or filtered air to keep the drive from overheating. This digital servo drive is also cooled by its built-in fan, and this fan must be able to operate without obstruction. The Allen-Bradley 1391-DES45-DI-AQB-A servo drive can be used at altitudes above 3300 feet if it is derated by 3% for every additional 1000 feet of altitude.
