Product Description:

The Pacific Scientific SC900 model 47147502, a highly advanced servo drive built to deliver precise performance in industrial environments.

This device offers 24-bit resolution per rotation that results in 0.0013 arc-minute precision, perfect for demanding technical operations. The servo drive maintains position accuracy within ±0.08 arc minutes rms or 2⁻¹⁸ revolutions because it delivers reliable operation through multiple cycles. The system validates different noise reduction methods to reduce output fluctuations. Under no filtering, the noise level stays below 0.3 arc minutes rms, while a 150 Hz single-pole filter reduces it to 0.16 arc minutes rms. The 10 Hz single pole filter provides effective noise suppression to achieve 0.04 arc minutes rms. Sensitive operations require equipment with these outstanding low-noise specifications. The DC offset temperature drift keeps errors within 0.08 arc minute per °C, which safeguards accuracy during temperature variations. The product's precision level stands at ±5.3 arc minutes yet rises to ±25 arc minutes when teamed with a 20 arc minute resolver to meet specific use conditions.

The 47147502 updates software at a lightning speed of 1 millisecond, so system downtime stays minimal and performance changes happen quickly. It handles temperature levels from 0°C to 25°C using natural convection to run at full power while operating under forced air between 0°C and 50°C with a slow power reduction to 60°C to suit industrial needs. The device supports different power input sources since its control power supply accepts voltage ranges from 90 to 264 VAC or 130 to 370 VDC. With a 3% or lower harmonic distortion level, the drive delivers consistent and clean electrical power, which follows EN 61800-3 standards to block outside electromagnetic interference.
