Buying Guide
- What voltage does your cart require? Most 400A controllers cover 36V to 48V systems. Match the voltage to avoid underpowered or overloaded performance.
- Which motor controller family is in your cart? Curtis 1268 SepEx, ITS-based controllers, and model 2CN090/1205 variations have specific compatibility. Pick a model confirmed to fit your cart’s controller family.
- Throttling input type matters. Some controllers use 0-5KΩ throttle ranges or ITS inputs. Ensure the throttle type matches your cart’s sensor for reliable speed control.
- Installation complexity. Some options are plug-and-play replacements; others require wiring harness checks or minor harness adaptation. If you’re not confident, choose a model marketed as easy install.
- Load and hill performance. For heavier loads or steep grades, select a controller that supports the full 400A while maintaining thermal protection to prevent overheating.
- Model compatibility check. Replacements often list several compatible part numbers (e.g., 1268-5403, 12685403). Confirm the exact part number on your old controller before ordering.
