4.7. Power Supply Sizing
The current loading on the power supply for a group of Ai2 Modules depends upon the Motor Type selected.
Each of the motor types available has an associated rated current that the motor will draw at rated torque
and maximum speed. Each motor type also has an associated allowed current draw that is available for a
period of time upon the initial starting of the motor. Theses current values and starting times are shown in
the following chart:
ECO BOOST
BOOST
8
Power supply load per Motor Port at rated torque at maximum speed 2.5 A 3.5 A 3.5 A
Power supply load per Motor Port during motor starting period 3.0 A 5.0 A 8.0 A
Duration of motor starting period 5.0 sec 1.5 sec 3.0 sec

Please note that the current values shown are per Motor Port, so if both Motor Ports are
being used on a given Ai2 Module, the current load seen by the power supply for that
module will be double the value shown.
*
The current values are at rated speed and at rated torque. The current will be less if rated
torque is not required by the motor.

Pulseroller assumes the user is aware of MDR power requirements for the application and
that the user and/or installer have properly sized 24VDC power supplies and wiring based
upon all applicable codes and standards. Pulseroller also assumes installation will follow
proper equipment grounding practices. “DC common or -”on all power supplies should
always be connected to ground. Improper power supply sizing and/or improper grounding
practices may produce unexpected results
