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.
