Servo Amplifier

Westwood, Mass. Model 5424AC servo amplifiers internal power supply eliminates the need for a separate isolated dc power supply. Optoisolation between power and signal circuits ensures electrical safety. Users can switch the amplifier between velocity-mode and torque-mode with an external toggle switch or command from a programmable controller.

Westwood, Mass. Model 5424AC servo amplifiers internal power supply eliminates the need for a separate isolated dc power supply. Optoisolation between power and signal circuits ensures electrical safety. Users can switch the amplifier between velocity-mode and torque-mode with an external toggle switch or command from a programmable controller. The 5424AC operates from 90 to 264 V ac at 50/60 Hz. The amplifier develops 20 A peak (10 A continuous) for driving brushless dc servo motors up to 2.5 hp. An internal frequency-to-voltage converter eliminates the need for motor tachometers in many applications. Users can set the maximum values for peak and continuous current as well as peak-current duration.
