Feature: 1. OE Number: The part numbers of controller for reference are 1205M 5601, 1205M 5603, please confirm whether it is consistent with the OE you need. 2. Fitment: The 1205M controller is replacement for Curtis, and fit for variour electrical vehicle including forklifts, transporters, if using other vehicles need to be programmed by yourself. 3. Programmable: The motor controller can be programmed using the 1313 4331 handheld programmer or the 1314 PC programming station, the use of the programmer also provides diagnostic and test functions. 4. Smooth and Quiet Operation: The motor controller uses high frequency switching and ultra low voltage drop to enable efficient and quiet motor speed and torque control. 5. Stable Working: Thermal protection and compensation circuits provide a constant current limit over the operating range, preventing sudden power outages and improving overall reliability. Undervoltage reduction prevents the battery voltage from being too low. 6. Easy Installation: The controller comes with push in connectors for easy installation and wiring, as well as a plated solid copper bus for strong power connections. Specification: Item Type: Motor ControllerProduct OE: 1205M 5601/1205M 5603 Operating Voltage: 36V Current: 500A Throttle Type: 0-5V Application: Replacement for Curtis, it can also be applied to forklifts, transport vehicles, etc. (If you use other vehicles, you need to program yourself) Detailed parameters: Nominal Battery Voltage (volt) : 36V 1 Minute Rated Current (ampere) : 500amps 5 Min Rated Current (ampere) : 350amps 1 hour Rated Current (ampere) : 200amps Plug Brake (A2 bus) : Yes PWM Operating Frequency: 15.6kHz Electrical Isolation from Radiator (minimum) : 500 VAC KSI Input Current (unengaged contactor) : 70 mA, no programmer required 130 mA with programmer Logic input current: <2mA Status LED output current (Maximum) : < 2 mA These controllers work with ten throttle types: Type 0:2 Line potentiometer, 0-5KΩ Type 1:2 wire potentiometer, 5KΩ-0 Type 2: Single ended 0-5V input Type 3:2 wire potentiometer, 4.6kΩ - 0 Type 4:2 wire potentiometer, 5.5kΩ - 0 Type 5:2 wire potentiometer, 1KΩ-0 Type 6: ITS input Type 7: Single ended 6.3-10.6V input Type 8: Single ended 6-12 V input Type 9: Single ended 3-wire potentiometer, 0-5KΩ Operating Environment Temperature Range: -40°C to 50°C Storage Environment Temperature Range: -40 ° C to 85 ° C Note: By default, the controllers we deliver are set to 36V / 500A / 0-5KΩ (throttle type = "0"). In order to better apply the controller to your system, the buyer should confirm with the seller the battery system voltage and throttle type (0-5kΩ, 5k-0Ω or 0-5V). Note: The J5 terminal of the new 1205M controller is not activated by default. The controller is wired the same as the old 1204M controller without the J5 terminal . Package List: 1 x Motor Controller Note: 1. Professional installation is recommended, for buyers with no experience in controller application, please consult your vehicle/motor dealer and read CURTIS 1204M/05M/09M/21M manual carefully before purchasing.2. Please double check the part number and fitment of your item, matching information is for reference only.
