Patented Spring Type |
| 12 VDC motor is
totally enclosed, permanent magnet type. Magnets act as a
secondary brake for added safety. This type of motor is smaller, cooler
running, more efficient and has higher duty cycles than series-wound
motors. Lower current draw provides for longer battery life.
The motor is also equipped with a thermal overload device that opens and
resets automatically. The rotation is reversible by reversing the
two color coded leads. Torque is the same in either
direction. |

24 VDC motor is
totally enclosed, permanent magnet type. This type of motor is
smaller, cooler running, more efficient and has higher duty cycles than
series wound motor. Lower current draw provides for longer battery
life. Rotation is reversible by reversing the two color coded
leads. Torque is the same in either direction. The motor is
also equipped with a thermal overload device that opens and resets
automatically. |
|
Controls
are also available for these actuator models as follows: |
- Control Package PDC -1R = MPD6905
- Control Package
PDC-2R = MPD6904
|
|
Additional
Notes |
- Some actuator surface temperatures may reach
230°F at or near maximum allowable duty cycle.
- The thermal overload resets in 10
minutes.
- All ratings are normal and based on
the actuator being broken in for approximately 2500 inches of travel.
- Duff-Norton PDC series control box
or 2 SPDT Relays (supplied by customer) are required to operate the
actuator.
