Overview

CURTIS 1204M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1204M controllers are updated versions of the popular 1204 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 1204M 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:

In this assemblage, the J5 terminal of new 1204M controllers is not activated. The controller wiring is same to the old 1204M controllers without J5 terminal.

KEY FEATURES

• CURTIS Model: 1204M-4201
  • Norminal Battery Voltage (Volts): 36V (default setting) or 24V
  • 2 Minute Current Rating (amps): 275
  • 5 Minute Current Rating (amps): 200
  • 1 Hour Current Rating (amps): 125
  • Plug Braking (A2 Busbar): Yes
• Assemblage Net Weight: 7.9 kg

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 1313-4331 Handheld Programmer or 1314 PC Programming Station.
• Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.

Installation Dimensions:

Equipped with a foot pedal throttle, the controller assemlage 1204M-4201 offers also a solution for replacing old CURTIS 1204 motor control unit. It may be installed as a direct replacement for CURTIS 1204 controller models listed below:

• 1204-001: 24-36V / 275A, 0-5K throttle
• 1204-004: 24-36V / 275A, 0-5K throttle
• 1204-015: 24-36V / 275A, 0-5K throttle
• 1204-018: 24-36V / 275A, 0-5V throttle
• 1204-022: 24-36V / 275A, 0-5K throttle
• 1204-026: 24-36V / 275A, 0-5V throttle
• 1204-027: 24-36V / 275A, 0-5K throttle
• 1204-031: 24-36V / 275A, 5K-0 throttle
• 1204-034: 24-36V / 275A, 0-5K throttle
• 1204-036: 24-36V / 275A, 0-5V throttle
• 1204-101: 24-36V / 175A, 0-5K throttle
• 1204-102: 24-36V / 175A, 0-5K throttle
• 1204-104: 24-36V / 175A, 0-5K throttle
• 1204-105: 24-36V / 175A, 0-5V throttle
• By default, we provide the controller assemblage 1204M-4201 only with a 0-5K foot pedal throttle EFP-001. If you don't want to used this throttle or need another throttle (for example, 0-5V foot pedal throttle RJSQ-001, 3-wire 0-5K foot pedal throttle JSQD-DWK-003D or ITS type 0-5V throttle FT-02YG), please contact us.
