Product Description:

The CU833-002 from Pacific Scientific slots into the PC800 - PCE800 Brushless Servo Drives lineup and brings reliable strength into automation. The continuous output current goes right up to 3.6A RMS at 25-40°C, sticking steady even when operating hours stretch out. Input voltage runs broad here — 323 to 528 VAC, three-phase, letting this model work in places where power fluctuations usually cause problems for other drives. Power output under constant running clocks in at 2.6 kW at 480V with convection cooling, so systems don’t get bogged down during heavier shifts. This servo drive never slacks on torque, either, with the peak output rating reaching 10.6A RMS just when extra kick from the motor is wanted.

For communications or setting parameters, interface choices stick out: this drive speaks using RS-232/485, and for more versatile tasks, also accepts +/-V DC, Step/Dir., and Indexing options. The layout includes efficiency on purpose — power stage efficiency stays high at 97%, keeping heat and wasted energy under control day after day. Only convection is needed for cooling; no loud fans or extra pieces demand attention, cutting down maintenance. Main power supply covers both high and control voltages. Industrial setups with long motor cable runs, sometimes even 50 meters or 164 feet, still stay reliable with this one in place. The shunt regulator, protecting drivetrain components, is ready for fast peaks too, holding up 10 kW for 300 ms when spikes jump out of nowhere.

Even in spots with voltage dips or long duty cycles, this servo drive holds parameters true. A quick-mount case sits firm and lets the drive slide onto control panels with no wrestling.
