Product Description:
The SCE903N3-000-01 is a servo drive which is intended for controlled and precise motor applications, and it is made by Pacific Scientific. This drive has an input voltage of 90 to 264 VAC for compatibility with global power standards.
The SCE903N3-000-0 servo drive efficiently runs in ambient temperatures of 0 to 25°C to provide optimal performance under controlled thermal environments. This servo drive remains functional in humidity conditions of 10% to 90% non-condensing for reliability in dissimilar industrial climates. This servo drive provides a maximum continuous output current of 5.3 A in convection cooling at 25°C, with stable operation for continuous-duty cycles. In high-demand situations, it supplies a peak output current of 10.6 A for 5 seconds, with operation maintained at temperatures up to 50°C, to accommodate momentary overloads and transient motor requirements. This drive has a peak output power of 5 kW at 400 VAC for 1 second, useful for applications where high torque is needed for short bursts of energy. This drive’s up to 0.75 seconds of maximum delay from the AC line to control supply activation, supports quick system readiness, along with effective power sequencing during startup processes.
The shunt regulator of this drive is designed with a peak power of 8 kW for 350 milliseconds, efficiently handling the regenerative energy in excess upon deceleration. The physical dimensions of the SCE903N3-000-01 drive are 370 mm x 85 mm x 229 mm, enabling integration into space-efficient control panels. This drive also supports cable lengths of motor power up to 50 meters, thus allowing flexibility in motor installation and system design. This servo drive’s external regeneration duty cycle for maximum external regeneration is capped at 10% to keep the shunt regulator well within safe energy dissipation margins. In addition, the internal bus capacitance of this servo drive can handle 27 joules of energy at a 650V nominal bus voltage to ensure electrical stability in transient conditions.
Frequently Asked Questions about SCE903N3-000-01:
Q: Why is the 0.75-second AC line to control delay important?
A: This delay ensures safe power sequencing and protects control circuitry during startup.
Q: What is the purpose of limiting the shunt regulator's duty cycle to 10%?
A: It prevents overheating and allows safe dissipation of excess energy during regenerative braking.
Q: How does the bus capacitance energy absorption of 27 J benefit the system?
A: It stabilizes the internal voltage during transient spikes, protecting sensitive components.
Q: Why does the SCE903N3-000-01 support up to 50 m motor cable length?
A: This feature enables greater flexibility in system design and motor placement without signal degradation.
Q: How does convection cooling affect the continuous output current of SCE903N3-000-01?
A: It allows the drive to deliver 5.3 A continuously without forced air, minimizing installation complexity.
