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 = PSPD 2775 & LSPD 2775
Control Package PDC-2R = PSPD 2774 & LSPD 2774

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
Two DPST-Normally Open relays (supplied by customer) are required to operate the actuator if the Duff-Norton Controls are not present.
