Considerations Before Choosing a 480VAC Conveyor System
Before choosing a 480VAC conveyor system, it’s important to evaluate your facility’s power infrastructure, load requirements, and operational goals. These systems are best suited for large-scale, continuous operations where high torque and long conveyor runs are necessary. You’ll also need to account for installation costs, electrical safety standards, and maintenance resources.
In many cases, a 24VDC conveyor system can achieve the same throughput with lower energy use, quieter operation, and simpler controls - making it a better fit for modern, flexible facilities.
Energy Consumption
-
AC Conveyor Systems consume 2–3x more energy than a comparable 24VDC MDR system handling the same throughput.
-
Energy usage increases with conveyor runtime and the weight of the load. Continuous-duty, heavy-load lines can quickly become expensive to operate.
-
24VDC MDR systems use low-voltage motors and distributed drives, meaning only active zones consume power. This makes them much more energy-efficient, especially in facilities with stop-and-start operation or intermittent use.
-
For heavy-duty, long-distance, continuous conveyors, AC systems remain the standard due to their torque and durability, but energy costs will be higher.
-
For medium-duty, modular, or intermittent conveyors, such as in e-commerce, order fulfillment, or automated sortation lines, 24VDC MDR systems are preferred because they minimize energy waste and reduce operating costs.
Safety
AC conveyors operate on high-voltage power, requiring strict adherence to electrical safety standards. Safety compliance is not a one-time step - it must be considered at every stage to ensure safe operation, reduce risk, and meet regulatory requirements.
To ensure safe operation:
-
Emergency stops, safety relays, and interlocks must be properly integrated into the control system.
-
Motors and drives should be enclosed or guarded to prevent contact.
-
Regular inspections of belts, rollers, and moving parts help prevent pinch-point injuries.
-
Training staff on lockout/tagout procedures is essential for maintenance.
-
Sensors and photoeyes should be configured to stop the conveyor immediately in case of product jams or unsafe conditions.

How is control different in a 24VDC MDR conveyor system?
A 480VAC conveyor depends on a central PLC and large motor drives. In contrast, a 24VDC conveyor uses decentralized zone control.
-
Each conveyor zone has its own 24VDC motorized roller and small controller board.
-
Logic is built into each zone, so cartons accumulate, start, and stop automatically without a large PLC.
-
Wiring is simpler, with low-voltage cables instead of high-voltage conduit.
-
Expansions or layout changes are easier because new zones can be added without major rewiring.
In short:
-
480VAC = centralized control, high power, more complex wiring.
-
24VDC = decentralized control, modular zones, safer and more flexible.
This is why many facilities retrofit sections of AC conveyors with 24VDC MDR conveyors - they reduce wiring costs, increase safety, and simplify future expansions.
Choosing the Right Conveyor System
480VAC conveyor systems remain the workhorse of industrial material handling - built for power, endurance, and reliability. They excel in heavy-load, long-distance, or continuous-duty environments where high torque and uptime are critical.
However, as energy efficiency and flexibility become higher priorities, and MDR (Motor-Driven Roller) performance continues to exceed expectations, many facilities are transitioning portions or all of their operations to 24VDC MDR technology for lighter-duty, modular, or accumulation zones.
A well-designed system can successfully blend both: 480VAC conveyors where strength and transportation matters most, and 24VDC MDR where control and efficiency drive performance. This hybrid approach maximizes throughput, minimizes operating costs, and extends system life.
