Product Description:
- CURTIS 1205M-6B403 DC Series Motor Controller
- Upgraded Version of 1205M-6B401 (Part Number: 17721701) & Fully Compatible
60/72V - 400A

EY Features:
- Curtis Model: 1205M-6B403
- Norminal Battery Voltage (Volts): 60V / 72V (Two voltage settings are available. The voltage can be set to either 60 volts or 72 volts. By defaut, it is set as 72 volts, with an allowable working range 48-72V. If it is set as 60 volts, the allowable working range is 39-60V).

The buyer should confirm with the seller the battery system voltage and the throttle type (0-5kΩ, 5k-0Ω or 0-5V). There is no extra cost for reprogramming the controller or other CURTIS programmable devices.

By defaut, we will the controller of setting of 72V / 400A / 0-5kΩ (Throttle Type = 0).

Wiring Diagram:By default, the J5 terminal of 1205M-6B403 controller is not activated. The controller wiring is same to the old 1204M controllers without J5 terminal.

Overview:
- Curtis 1205M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1205M controllers are updated versions of the popular 1205 controllers, with the added functionality of being programmable—via the Curtis Model 1313-4431 Handhold Programmer or 1314-4402 PC Programming Station. This means the controllers  can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.
- Curtis 1205M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.

Features include:
- High-frequency switching and ultra-low voltage drops provide high efficiency and silent operation.
- Simple mounting and wiring with push-on connectors for control signals and plated solid copper buses for power connections.
- Compatible with either a two-wire potentiometer or a voltage throttle.
- Throttle fault protection circuitry disables controller if throttle wires become open.
- High pedal disable feature prevents controller operation if key is turned on while throttle is applied.
- Plug braking diode internal to controller.
- Thermal protection and compensation circuit provides constant current limit over operating range and during under/over temperature cutback; no sudden loss of power under any thermal conditions.
- Undervoltage cutback function protects against low battery voltage, including low voltage caused by external loads.
- Easily programmable through the Curtis Model 1313-4431 Handhold Programmer or 1314-4402 PC Programming Station.
- Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.
