EBS852

Micro processor controlled power electronics with integrated frequency converter

During continuous positioning the power electronic unit varies the motor torque steplessly until the actuator force and the restoring process forces are balanced. High response sensitivity and positioning accuracy ensure an excellent control quality and a long actuator life expectancy.
  • Conventional signal interface (0/4 ... 20 mA / 24 V)
  • Digital communication via RS 232 and HART
  • Additional functions such as process controller, maintenance computer, programmable characteristics
  • Rack installation; protection class IP 20
  • Torque, speed variation and continuous positioning
