ATM's motor driven phase shifters utilize DC motors with integrated, long life gear reductions ideal for High Reliability applications.

The unit will operate with a set DC voltage between 18-30VDC, commonly found in most systems or by a separate DC power supply. Motor speed will vary based on Voltage used. Maximum running current is 250mA & 600mA max starting.

To prevent motor damage, Micro switches are used to stop the motor at the minimum and maximum travel positions
Units are provided with a 9 pin D Sub Male connector allowing for control voltage, end point indication if desired, and follower potentiometer. See connector pin-out details.
These devices are best controlled by an external Double-Pole/Double-Throw (DPDT) switch or the optional ATM External control module.
Any one of ATM's Phase Shifters can be mounted to a motor drive.

Interface

1. Motor Control Voltage
Pins 2 and 7 of the nine pin D Sub male connector will have fixed DC voltage between 18-30 volts applied. To increase phase pin 2 is (+) and pin 7 is (-). To reverse the direction 2 is (-) and 7 is (+). In both directions a stop is provided by means of Micro switches.

2. End Point Indicator *
The switch is also used to provide end point indication by means of pins 1 and 6 developing a voltage when the device has reached the maximum limit, (for 2+ and 7-). Pins will 3 and 8 will develop a voltage when a minimum limit is met. (for 2- and 7+). The developing voltage is equal to supply voltage used.

3. Follower Potentiometer **
A 10K Pot with an output proportional to the position of the motor drive mechanism is available at pins 4, 5, and 9.

* When ordering a Motor Driven Phase Shifter, you will need to create the actual model number, based on the specific phaseshifter of you choosing by adding the suffix -28 at the end of the model number. See our Phase Shifter page to find the 30°, 60°, 90°, 180° or 360° model you wish to start with. Example: P/N P1604 becomes P1604-28 when ordering as a motor driven unit. Any one of ATM's Phase Shifters can be mounted to a motor drive.

Optional External Control Module

An External Drive Control Module, part number MCM-001 shown at right, is available for the motor drive as an optional accessory. It includes:

1.  Crisp tactile switches to control drive.
2. Max/Min position indicator lights.
3. Follower potentiometer terminals.
4.  Self-switching power supply with input of 120 VAC - 240VAC.*
5.  6 Ft, 9 pin cable to interconnect the control box to the motor driven device.

*If supplied power source is not used, an input of 18-30 VDC through the 9 pin connector may be substituted.
