CURTIS DC Series Winding Motor Speed Controller Assemblage

48V / 60V / 72V (80V) - 550A, maximum motor power rate 17.00 kW @ 80V

This 1221M-6701 controller assemblage is a complete electric vehicle DC Series Motor control system. The assemblage includes:

Mating Connectors & Installation Kit

This controller assemblage is a complete motor control system, including:

• CURTIS controller
• Main contactor
• Forward / reverse contactor
• Fuses:
  • Power wiring fuse
  • Control wiring fuse
• Wiring & connectors (mating connectors are included)
• Heat-sink aluminium alloy installation plate
• Foot pedal accelerator (2-wire 0-5K potentiometer throttle)
• Electric accessories:
  • Coil suppression diode
  • Precharge resistor
• Installation (bolts, washes and nuts) kit Included

For more installtion details, please take reference with the 1221M Controller Assemblage Connectors' Definition (PDF format) and 1221M Controller Assemblage Installation Instruction (PDF format).

Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1204M/05M/09M/21M Manual before making the purchase.

Overview:

With its potentiality of driving high power rate DC series winding motor of upto 80V, CURTIS 1221M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1221M controllers are updated versions of the popular 1209 / 1209B / 1221 controllers, with the added functionality of being programmable - via the CURTIS Model 1313-4331 Handheld Programmer or 1314 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 1221M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.

Wiring Diagram:

 

By default, the controller J5 terminal is not activated. If you want to activate the J5 terminal for using the Rev Input / Main Driver functions, please see the page 7 and 8 of 1204M / 1205M / 1221M controller manual (PDF format).

CURTIS 1221M-6701 series controller assemblage key features:

• CURTIS Model: 1221M-6701
  • Norminal Battery Voltage (Volts): 48V, 60V and 72V (80V)
  • 1 Minute Current Rating (amps): 550
  • 5 Minute Current Rating (amps): 375
  • 1 Hour Current Rating (amps): 225
  • Plug Braking (A2 Busbar): Yes
• Proposed motor power rate: 8.0 - 15.6 kW
• Simple motor connecting labels on assemblage
• Easy installation with components mounted on a heat-sink aluminium alloy installation plate
• Including a foot pedal accelerator (throttle)
• Simple plug-in connctors (1221M Controller Assemblage Connectors' Definition (PDF format))
• Easy to install (1221M Controller Assemblage Installation Instruction (PDF format))
• Reinforced carton package, safe for international delivery
• Assemblage Net Weight: 13.4 kg
• Package Weight: 15.8 kg (including the foot pedal throttle)

Controller features also 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.
• The controller assemblage includes a 2-wire 0-5kΩ potentiometer throttle EFP-001 (controller setting: Throttle Type = "0") (Multiple throttle types can be used with 1221M-6701 controller. If you want to use a throttle type of different type than type "0", for example a 0-5V voltage throttle, please contact us.)
• 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 1313-4331 Handheld Programmer or 1314 PC Programming Station.
• Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.
