Voice Coil Motor Driver with PWM Input

800 Series

 

 

Enlarge

The 800 series is a high performance, cost effective DC Motor Driver to implement intelligent Motion Control. The driver incorporates surface mount technology to achieve an exceptional power density.

This driver does not accept any type of feedback. It may be used in open loop applications. This module may also be used as a driver with a controller that accepts feedback and generates "PWM and direction outputs".
Features:
  • Run DC and Voice Coil Motors with PWM and Direction Control Inputs
  • 4 Amp Motor Output
  • +6 VDC to +30 VDC Power Supply
  • 0 ºC to 70 ºC Operating Temperature
  • Light: 0.36 Oz (10 gm)
  • PWM Frequency up to 40 KHz
