Product Description:
The SC903-031-01 Servo Drive is designed by Pacific Scientific for precision control. It supports dynamic motor applications with robust performance. It operates efficiently in various industrial automation systems.
The SC903-031-01 servo drive operates within a voltage range of 90 - 264 Vac and is suitable for both single and three phase systems. It delivers a peak output current of 15 A for up to 5 seconds at 50 °C and maintains continuous output current of 7.5 A under convection cooling at 25 °C and forced air cooling at 50 °C. The peak output power reaches 4.5 kW at 240 VAC for 1 second while continuous output power is 2.2 kW under the same voltage and cooling conditions. This drive exhibits high power stage efficiency of 96 % at continuous power. Its shunt regulator handles a peak power of 6.0 kW for 300 mSec and continuous power up to 50 W with forced air cooling at 50 °C. The maximum external regeneration duty cycle is 12 %. Bus capacitance energy absorption is rated at 15 J from a 320 V nominal bus and the output current ripple frequency stands at 20 kHz.
The SC903-031-01 servo drive supports a transformer suggested kVA of 3 to 4 kVA with a maximum AC line capacity of 100 kVA. It handles an inrush peak current of 340 A with a pulse width of 2 msec using a 20 A 250 V time delay fuse. The minimum motor inductance is 2.0 mH while the maximum inductance reaches 2 H. This SC900 Servo drive includes extensive protection circuits and diagnostic tools for easy setup along with an IGBT power stage that operates with high-frequency PWM.
