PZ9A150UXXXC03
by Sanyo Denki
The Sanyo Denki PZ9A150UXXXC03 is an AC servo amplifier from the PZ BL Super Servo Amplifiers series, designed to deliver high-performance motion control in demanding industrial applications. This unit features a rated voltage of 380 VAC and a rated output current of 150 A, ensuring robust power delivery to connected servo motors. Its primary function is to amplify command signals into precise motor drive currents, making it ideal for CNC machines, robotics, and other automated systems requiring accurate speed and torque control.
Built with a forced-air cooling method to maintain optimal operating temperatures, the PZ9A150UXXXC03 operates efficiently at an input frequency of 50/60 Hz and achieves an efficiency of ≥95%. It employs a PWM switching frequency of 8 kHz for smooth current waveforms and reduced audible noise. The amplifier withstands a dielectric strength of 1500 VAC for 1 minute and maintains an insulation resistance of ≥10 MΩ at 500 VDC, ensuring electrical safety and reliability. Overload capacity reaches 150% of nominal current (short-term), and built-in protection features guard against overcurrent, overvoltage, and overtemperature conditions.
This device supports both digital and analog control signals via its versatile communication interface. It operates reliably in ambient temperatures from 0 to +40°C and can be stored between –20 and +65°C under non-condensing humidity of 20–90%. Weighing 20 kg, the amplifier integrates easily into existing rack or panel layouts. Certified by TÜV and UL, it meets international safety standards for industrial automation. By combining high power density, advanced protection, and broad compatibility with systems such as ABS-RII and ABS-E, the PZ9A150UXXXC03 enhances system responsiveness, reduces downtime, and delivers consistent performance across diverse manufacturing environments.
