Product Description:
Pacific Scientific manufactures the SC102-010-T4 as part of its SC100 Brushless Servo Controllers series. The unit is an industrial brushless servo controller that processes tachometer feedback to modulate motor current for precision automation. By converting three-phase mains power into a regulated DC bus, the controller supplies torque and speed commands to synchronous or permanent-magnet servomotors used on packaging lines, robotic axes, and material-handling equipment. Its compact chassis fits in panel racks and integrates with PLCs through discrete logic and analog velocity references.
The controller rectifies a three-phase 230 VAC supply, accepted within a +10/-15% tolerance window, into a nominal 320 VDC bus. In steady-state service, it delivers 12 A of phase current, which matches its stall rating, and it provides up to 3.6 kW of mechanical power across the full 0 °C to 50 °C operating range. Excess regenerated energy is bled through an internal shunt that can dissipate 30 W continuously, while total heat generation inside the enclosure reaches 90 W at full load. With a conversion efficiency above 95%, the design limits panel heating. Tachometer feedback is handled by the Tachsyn processor, which interprets a 4.0 V/Krpm gradient for closed-loop velocity control. Carrier modulation occurs at a 5 kHz switching frequency, and altitude capability extends to 1500 m.
During acceleration, the drive furnishes 15 A for up to five seconds, yielding a momentary output of 4.5 kW and allowing the shunt to absorb 8 kW for 300 ms. The wide input frequency range of 47–63 Hz lets the device run from utility or generator sources without adjustment. Three input phases keep rectifier loading symmetrical, and the rated switching frequency helps reduce ripple torque. Storage limits between -55 °C and 70 °C protect components before installation, while full functional ratings are maintained up to 50 °C ambient. Output may be derated when ambient temperature exceeds this threshold or when cabinet ventilation is limited.
