Electrical Performance and Stability
Voltage Flexibility
The 36–48V operating range allows this controller to work across different battery configurations commonly found in Genie lifts. Whether the machine uses a 36V or 48V battery pack, the controller automatically accommodates the system without additional adapters.
High Current Capacity
With a 500A maximum current rating, the controller handles:
- Heavy loads at full extension
- Steep grades and uneven terrain
- Continuous duty cycles
This high current tolerance reduces the risk of overheating and power loss during demanding operations.
SepEx Motor Control Advantages
SepEx motor systems separate the armature and field circuits, offering improved control over speed and torque. The AIVWUMOT controller fully supports these advantages:
- Smooth acceleration from standstill
- Consistent torque under varying loads
- Enhanced braking control
- Improved directional switching
For aerial lifts, these features translate into safer, more predictable movement at height.
Build Quality and Durability
Industrial-Grade Construction
The controller housing is designed to withstand:
- Vibration from continuous machine movement
- Temperature fluctuations in outdoor environments
- Electrical stress from repeated high-current cycles
Internal components are selected for stability and long service life, making the controller suitable for rental fleets and high-use equipment.
Environmental Resistance
While installation location varies by lift model, the controller is built to tolerate:
- Dust exposure
- Moisture from condensation
- Normal wash-down procedures
Proper mounting and sealing further enhance longevity.
Installation Considerations
The AIVWUMOT controller is intended as a direct replacement for the listed Genie part numbers. In most cases, installation involves:
- Powering down and isolating the battery system
- Removing the existing controller
- Transferring cables and connectors
- Securing the new controller in place
- Verifying correct operation
Because the controller matches OEM electrical specifications, additional programming is typically unnecessary.
Safety and Operational Reliability
Built-In Protective Functions
High-quality DC motor controllers incorporate protective logic to prevent damage to the lift and electrical system. While internal firmware details are proprietary, controllers in this class typically include:
- Overcurrent protection
- Thermal limiting
- Controlled ramp-up and ramp-down
- Fault detection and shutdown behavior
These safeguards help protect motors, batteries, and wiring during abnormal conditions.
