Product Description:
As a new member of Pacific Scientific’s renowned SC100 Brushless Servo Controllers lineup, the SC104‑001‑M introduces as a high‑precision motion solution. The module’s regulator delivers 30 W of continuous power to support stable thermal performance. A peak shunt regulator capacity offering 15 kW (300 ms) shields the system from sudden voltage surges. Featuring an efficiency of greater than 95 percent at a rated continuous power, it maximizes energy savings and minimizes heat generation.
It works on 3 input phases and ensures balanced current delivery and smooths motor operation. A nominal bus voltage of 320 VDC supplies consistent drive headroom which manages high‑voltage applications. Delivering short-burst torque for swift acceleration, the gadget unleashes an output power of maximum 17 kW (5 s). Drive’s peak output current reaches 60 A (5 s) that can handle transient high‑load conditions. Continuous stall output power of 6 kW for this controller maintains moderate loads which enables prolonged low‑speed operation. Also, the continuous stall output current of 20 A maintains torque under stall conditions thus protects against motor stalls. A current‑loop bandwidth of 800 Hz delivers tight current regulation to enhance dynamic response.
Switching occurs at 5 kHz which balances efficiency and switching losses. Weighing 16 lbs., this product variant eases rack mounting and handling. Ambient temperature range of 0°C to 50°C suits typical industrial environments. Dimensions of the controller measures at 16 × 12 × 10 inches provide a compact footprint, and hence it simplifies panel integration. Operating on an input voltage of 230 VAC (+10 percent, -15 percent) within a 47-63 Hz frequency range, it easily aligns with international mains power standards. The customization option of standard controller denotes base configuration while the option code of Hall sensor or Brushless tachometer interface allows direct feedback integration. Its high‑frequency PWM current control method achieves precise torque delivery. Also, the module uses a screw-terminal connection that further enhances vibration resistance.
Frequently Asked Questions about SC104-001-M:
Q: What does the SC104‑001‑M’s continuous power rating indicate?
A: This continuous power rating specifies the 30W regulator power the controller can deliver indefinitely under thermal limits. It ensures uninterrupted operation during standard duty cycles without triggering thermal shutdown.
Q: How does the SC104‑001‑M handle brief power surges?
A: It employs a shunt regulator peak capacity of 15 kW for 300 ms to absorb transient overvoltage, which protects internal electronics and connected motors from sudden current spikes.
Q: How many phases supply the SC104‑001‑M’s AC input?
A: The 3 input phases feed the controller and balances phase currents and reduces input harmonic distortion for smoother motor torque production.
Q: Why is high efficiency important for the SC104‑001‑M servo motor?
A: The device’s efficiency exceeding 95% at rated continuous power minimizes wasted energy as heat, which reduces cooling requirements and supports higher ambient operating temperatures.
Q: What benefits arise from a 320 VDC nominal bus voltage?
A: A 320 VDC bus from SC104‑001‑M offers ample voltage headroom for high‑speed motor operation, which delivers consistent torque output across the full speed range.
