Power Supply Requirements

The power supply for any and all EZ-Qube modules should meet the following requirements:

  • Certified as a NEC Class II device
  • Capable of detecting and properly handling short circuit and overload of its DC power output
  • Capable of supplying 24VDC at a minimum of 5 A for 1.5 seconds (BOOST Mode starting current time)

Power Supply Grounding

Power Supply Sizing

The current loading on the power supply for a group of EZ-Qubes 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
Power supply load at rated torque at maximum speed 2.5 A 3.5 A
Power supply load during motor starting period 3.0 A 5.0 A
Duration of motor starting period 1.5 sec 1.5 sec
