Mating Connectors & Installation Kit

Overview:

This 1204M-5305 controller assemblage is a completed electric vehicle DC Series Motor control system. The assemblage includes:

• controller
• main contactor
• forward / reverse contactor
• fuses
• wiring
• heat-sink aluminium alloy installation plate
• foot pedal accelerator (throttle)
• plug-in connectors
• installation (bolts, washes and nuts) kit Included

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.
