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 catch, 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 circuits, a operator with an increased motor duty cycle (HD) should be selected
  • 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 and control voltage: 24 V-DC
  • When the output speed is increased (operation with frequency converter), 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 variants 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

* The values given were determined for an even distribution of the cycles. A cycle consists of two movements (opening and closing) and has a deflection of 10 revolutions of the output shaft in each direction. At ambient temperatures between 40°C and 60°C, a reduction of the maximum cycles per hour by 50% must be taken into account.

** For vertically moving doors and roller shutters, a reduction of the specified pull force by a further 20% may be necessary. Possible reasons for this are, for example, additional seals, double-walled profiles or an unfavorable winding ratio where the door height exceeds the door width. In addition, it should be noted that the maximum torque only occurs after one to two revolutions when thick or high profiles are used.

*** Alternative limit switch ratios are available upon request.
