Standard Features
MAR 10, 50, 90
The percentage of time the electric motor is
energized vs. the time it is at rest, in reversing
duty and with the actuator running at it’s rated
load - maximum published torque.
Duty Cycle
• 12 motor starts (corrections) per minute.
• At the rated duty cycle for that model.
• With the speed of operation a minimum
of 15 seconds for 90° or slower.
• With positioning accuracy of (+/-) 1% of total span.

Note — Multi-turn models are available with the following number of turns:
1.4, 5, 8, 13, 18, 26 or 50. Must be specified when the order is placed.
To operate multiple actuators in parallel from
a single signal requires isolating relays in the
field wiring. Consult factory.
