Product Description:
The Pacific Scientific SC723A-001-PM72012 Controller features an output current of 15 amperes at 50°C for peak operation over 5 seconds. Its shunt regulator delivers continuous power of 40 kW and its ripple frequency is maintained at 20 kilo hertz ± 15%. Its velocity offset is adjustable to zero that enables accurate speed calibration in industrial automation applications.
The SC723A-001-PM72012 controller current loop bandwidth falls between 750-3000 hertz. It has a 12 bit RDC with ±22 arcmin accuracy and 1024 ppr enhances precise position feedback for resolver feedback systems. It utilizes a control logic power input voltage of 90 to 264 Vac at 47 to 63 hertz for one phase operation. Its continuous stall output current at 50°C is 7.5 A and it uses a brushless resolver for feedback mechanism. This module's bus power input voltage is rated for 120 Vac or 240 Vax at 47 to 63 hertz for both single and three phase operation. Its RMS bus current at 240 Vac with 3 phase input is 9 RMS that allows it to manage current accurately. It has a peak output power value reaching 4.5 kW at 240 Vac over 5 seconds with three phase input. It is a torque/velocity controller w/encoder emulator that makes it well suited to integrate in industrial automation.
This SC723A-001-PM72012 controller has a continuous power level code of 7.5 amperes and peak value of 15 amperes. Its velocity input command is ±10 volts and its efficiency remains above 95% at 50% output voltage and rated continuous current. It has a form factor of less than 1.01 that makes it easily placed in a compact environment.
Frequently Asked Questions about SC723A-001-PM72012:
Q: What does the 20 kHz ripple frequency mean for output performance?
A: A 20 kHz ripple frequency ensures minimal interference with motor control signals. It also reduces audible noise and helps maintain smoother torque output.
Q: Can the SC723A-001-PM72012 handle brief high-load events without triggering faults?
A: Yes, it delivers 15 A peak for 5 seconds, allowing safe handling of momentary high current demands. This supports load surges during acceleration or positioning without shutdown.
Q: How does adjustable velocity offset affect tuning accuracy?
A: It allows fine correction of any zero-speed drift in analog velocity inputs. This improves control precision in sensitive low-speed applications.
Q: What is the benefit of a 750–3000 Hz current loop bandwidth?
A: It enables fast current regulation response that enhances torque control accuracy. Higher bandwidth supports better performance in dynamic motion profiles.
Q: Why is a 12-bit RDC with ±22 arcmin resolution important?
A: It ensures precise rotor position detection when using resolvers. This level of accuracy directly influences velocity and torque loop stability.
