CURTIS DC SepEx Motor Controller Assembly

Model: 1266A-5201, 36-48V, 275A

Model: 1266R-5351, 36-48V, 350A

Specifications:

• Proposed SepEx motor power rate:
  • Model 1266A-5201:
    • 36V system: ≤ 3.8 kW
    • 48V system: ≤ 4.7 kW
  • Model 1266R-5351:
    • 36V system: ≤ 4.5 kW
    • 48V system: ≤ 5.4 kW
• simple motor connecting labels on assemblage
• easy installation with components mounted on a heat-sink aluminium alloy installation plate
• foot pedal accelerator (throttle), pre-wired for assemblage
• simple plug-in connctors
• Easy to install (1266A / 1266R CURTIS DC SepEx Controller Assemblage Installation Instruction (PDF format))

This 1266A-5201 / 1266R-5351 controller assemblage is a completed electric vehicle DC SepEx Motor control system. The assemblage includes:

• controller
• main contactor
• fuses
• heat-sink aluminium alloy installation plate
• foot pedal accelerator (3-wire potentiometer throttle JSQD-DWK-003D)
• plug-in connectors
• installation (bolts, washes and nuts) kit Included
• harness (optional. If you need the harness, please check the speed sensor connector form of your motor.)

If you need the harness, please check the speed sensor connector form of your motor. By default, we will provide the AMP flat type 3-Pin connctor.

For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1266A / 1266R Controller Manual before making the purchase.

We may reprogram the controller for adapting itself to your vehicle's specification. You may send us the list of parameters to be modified (example: for setting the speed limit, we may need to know the tire diameter, gear ratio, number of magnetic poles in the speed sensor magnet and speed expectation). There is no extra cost for reprogramming the controller.

Overview:

CURTIS 1266A / 1266R controllers are separately excited motor speed controllers designed for use in a variety of transport vehicles. These programmable controllers are simple to install, efficient, and cost effective. Typical applications include golf carts and small utility vehicles.

The 1266A / 1266R controller offers smooth, silent, cost effective control of motor speed and torque. The speed sensor input allows superior closed-loop control for regulating vehicle speed. Unique braking parameters allow simple, intuitive deceleration tuning. A full-bridge field winding control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and regenerative braking power without additional relays or contactors.

Key Features:

• Assemblage Net Weight: 4.6 kg (with foot pedal throttle)
• Package Weight: 6.4 kg (reinforced carton package, safe for international shipment)

Features Include:

• Regenerative braking, providing longer operation on a single battery charge and reducing motor brush wear and motor heating
• Adjustable brake rates, for smooth pedal-release braking
• Two user-selectable vehicle operating personalities, with vehicle top speed controlled and limited in each mode
• Motor parameters are programmable to match the characteristics of the specific motor being used
• Vehicle speed control is enhanced through feedback from a Hall effect speed sensor
• Anti-rollback function, providing improved control when throttle is released on hills
• Anti-stall function helps prevent motor commutator damage
• High pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startup
• Complete diagnostics through CURTIS 1313-4331 Handheld Programmer or 1314 PC Programming Station and through the built-in Status LED, for quick and easy testing, diagnostics, and parameter adjustment
• WalkAway™ braking feature limits any stopped or key-off rolling to a very low speed
• Auxiliary driver can be programmed for either an electromagnetic (EM) brake or a WalkAway™ relay
• Coil driver provides adjustable pull-in and holding voltages to WalkAway™ relay or EM brake
• Two fault outputs provide diagnostics to remotely mounted displays
• Reverse signal driver provides a low signal any time the vehicle is traveling in reverse
• Driver outputs are short circuit protected and provide built-in coil spike protection
• Brake/Drive Interlock meets ISO stopping distance requirements
• Warning buzzer sounds steady in reverse, intermittent during WalkAway™ braking
• Splash resistant plastic cover
• Meets or exceeds EEC fault detect requirements
