Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1268 Controller Manual (PDF format) before making the purchase. Notice: By default, we will deliver the controller with default setting of 48V / 400A. If you need to modify any controller parameter, please send us a message with the list of parameters to be modified (Click here to download the parameter list of default setting of controller 1268-5403, PDF format). Notice: We supply also the 1268-5403 controller assemblage with throttle (foot pedal).

Overview: CURTIS 1268 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 heavy-duty golf carts, personnel transports, burden carriers, and other utility vehicles. The 1268 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: CURTIS Model: 1268-5403 Norminal Battery Voltage (Volts): 48V (default setting) or 36V Amature 2 minute current rating (amps): 400 Field 2 minute current rating (amps): 50 Logic enable and logic power input voltage (minimum): 16.8 V Logic enable and logic power input current (no contactors engaged): 160 mA without programmer; 200 mA with programmer Logic input voltage: 20.0 V High; 7.5 V Low Logic input current 10 mA Throttle Type: various throttles can be used with the 1268 controller, including 5kΩ 3-wire potentiometers and 0–5V throttles. Dimensions: L229xW178xH81 mm Net Weight: 3.9 kg Package environmental rating: IP64, IP67

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
