Product Description:
Pacific Scientific’s SC105-001-M current loop bandwidth of 800 Hz nominal accelerates feedback response. Its continuous stall output power of 9 kW sustains motor drive under locked rotor conditions which eases low‑speed control in heavy machinery. Efficiency showing over 95% at rated continuous power minimizes energy loss and lowers temperature rise and extends component life. A shunt regulator power continuous rating of 60 W handles steady regenerative currents to protect internal electronics elements from undervoltage conditions.
Input voltage tolerance at 230 VAC (+10%, –15%) across 47–63 Hz adapts to fluctuating line supplies, ensuring consistent start‑up under diverse power grids. The thermal management is processed with fan‑cooled technology that maintains optimal operating temperatures and preserves performance under sustained load. A mass of 16 lbs. facilitates single‑person installation which speeds up integration into control panels. Delivering a peak output current of 60 A for up to 5s and with 3 input phases, it balances power delivery across windings and also smooths torque output. The controller possesses peak output power of 17 kW over five seconds that delivers short‑duration surge capability and addresses rapid acceleration demands.
The 320 V DC is a nominal bus voltage by this brushless servo motor and a temperature between 0°C to 50°C matches typical plant climates which removes extra cooling requirements. The shunt regulator handles brief energy surges with a 15-kW power peak sustained over 300 ms, thus effectively suppressing voltage overshoots caused by transients. Further, a continuous stall output current of 40 A defines sustained current handling and avoids drive derating in stall conditions. Switching frequency set at 5 kHz to optimize PWM resolution, thus refines current waveform fidelity at high speeds. The relative humidity tolerance from 5 to 95% (non‑condensing) keeps the controller resilient in moist environments.
Frequently Asked Questions about SC105-001-M:
Q: What makes the SC105-001-M ideal for industrial servo control applications?
A: Its 800 Hz current loop bandwidth provides fast torque regulation during rapid load changes, making it ideal for precision-heavy machinery and automation systems.
