Product Description:
The SC103-001-T4 is a brushless servo controller manufactured by Pacific Scientific as part of the SC100 Brushless Servo Controllers series. Intended for closed-loop motion platforms, it regulates three-phase permanent-magnet motors by modulating DC bus energy and returning excess energy through an onboard shunt. In automated cells, the unit links the drive amplifier to feedback devices, providing velocity and torque control for indexing tables, pick-and-place axes, and packaging machinery. This arrangement lets the controller respond quickly to load changes while maintaining stable closed-loop motion.
A nominal bus of 320 VDC is developed from a 230 VAC supply that may vary by +10%/-15% at 47-63 Hz across three input phases. It can supply 15 A continuously, and the controller supports 4.5 kW of motor output while dissipating 105 W as heat through its chassis. For transient moves lasting up to five seconds, the current rises to 30 A and output increases to 9 kW. Regenerated energy is absorbed by a shunt path rated for 30 W continuously and up to 8 kW during 300 ms events. The distinction between continuous and peak output helps clarify how the controller behaves during steady running and short acceleration bursts. The current loop closes at 800 Hz, and the PWM stage switches at 5 kHz to support linear torque production. Command and feedback are processed by a Tachsyn interface, and the tachometer gradient is 4.0 V/krpm for velocity scaling.
The controller operates with > 95% efficiency, which helps limit waste heat during normal use. Full ratings remain valid from 0 °C to 50 °C, aided by a switching topology that helps control internal temperature rise. When powered down, the unit can be stored or transported from -55 °C to 70 °C without insulation damage or parameter drift. Adequate airflow is still required when the controller is installed in an enclosed cabinet.
