MDF 05-14-12

The operators of the MDF series are suitable for 3-phase current (3-phase alternating current) and, with a complete series from 100 to 2000 Nm in this range, offer the right solution for every on-site situation. In addition, special solutions for individual customer requirements can be realized flexibly and quickly at any time.

MDF 05-14-12

Features:

  • Rolled worm shaft
  • Emergency operation via emergency hand crank "KU" (1-sided) or "KU-KU" (2-sided up to 420 Nm & 12 rpm) or emergency hand chain "KE
  • Easy conversion from crank to chain
  • Integrated safety gear, independent of position and speed, maintenance- and wear-free, integrated cushioning
  • Pendulum foot support
  • Supply: 230/400 V/3~/50 Hz
  • Thermal protection in the motor winding
  • For gate systems with above-average switching operations, select an operator with increased motor duty cycle (HD).
  • Pluggable connectors
  • End position setting via electronic absolute encoder (AWG) or mechanical limit switches (MEC)
  • Version with external control, can be combined with extensive control program. Supply: 230/400 V/3~, frequency: 50/60 Hz, control voltage: 24 V-DC
  • When the output speed is increased (operation with frequency inverter), the output torque is reduced. In this case, the following applies: An increase of the output speed by 10 % causes a reduction of the output torque by 5 %.
  • Special designs such as other voltages and frequencies, different output speeds, higher degrees of protection and hollow shaft Ø on request
  • ATEX version available (see chapter "Operators for hazardous areas")
  • For temperature ranges below -20 °C there is suitable oil and electric heating on request
