CT-302S9 Controller Product Specification TNC Scooters Sales - Service - Parts CT-302S9 - Technical Parameters Rated Voltage 24 Volts Rated Current 10.5 Amps Rated Motor ≤ 250 Watts Rated Charger ≤ 3.0 Amps Conversion Efficency 95% Under Voltage Protection 20.5 Volts Speed Control Available (Turn or Thumb Throttle) Brake Indicator Available Power Indicator Available Dimensions 88 mm x 50 mm x 35 mm CT-302S9 - Protection Circuits Current Limiting This prevents the motor current from exceeding the specified value avoiding damage to the motor and the controller due to over current conditions. Under Voltage Protection When battery voltage falls to a specified value, the controller cuts off battery output preventing over discharge and extending battery life. (The cutoff value is approximately 20.5 volts, but varies drastically from controller to controller.) Over Speed Prevention While Charging When charging, the controller renders the throttle temporarily inoperable, preventing mistaken manipulation. (This function is not available in some applications.) Power Cut Off During Braking When underway the brake switch signals the controller to cut the battery output.
