About 1391B-ESAZ45-AQB

The Allen-Bradley 1391B-ESAZ45-AQB is a 45-Amp AC servo controller. It can handle a 300V DC nominal bus output voltage and a circuit breaker input rating (in systemetrical amps) is 1300 A. Its static gain (measured in A/RMS) is 1.5 x Rated Motor Current/rpm, its speed regulation changes at up to 0.05% of the motor’s maximum speed with a 95% load, and its form factor 1.03 or less.

The 1391B-ESAZ45-AQB can operate in an industrial environment with an ambient temperature range between 32 and 140 ^oF (0 and 60 ^oC), and it can be stored in an environment whose ambient temperature range is 32-149 ^oF (0-65 ^oC). It can operate and be stored anywhere with an ambient humidity level between 5 and 95% if the humidity is non-condensing.

The 1391B-ESAZ45-AQB’s deadband rating is 0 and its integral fan output is 50 CFM without a load on it. The servo controller can function fully at an altitude as high as 3300 feet.

From the transformer, the 1391B-ESAZ45-AQB’S input voltage power is 230V AC (3-phase) at 50-60 Hz and +/- 3 Hz while the control voltage is 36V AC single-phase CT. The 1391B-ESAZ45-AQB’s transfer input tolerance is between 10% and -15%.

The 1391B-ESAZ45-AQB has a high controller efficiency of up to 85% at the minimum rated load and at its modulation frequency is 2500 Hz at 10% or -10%. Its drift, when referred to the tach, is a maximum drift of 0.07 RPM per degree Celsius. The 1391B-ESAZ45-AQB’s peak current time will vary with the RMS’s current history.
