Specifications:

• PWM operating frequency: 16 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• KSI input voltage (minimum): 16.8 V

Overview:

CURTIS 1266 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 1266 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 Feature:

• CURTIS Model: 1266A-5201
• Norminal Battery Voltage (Volts): 48V (default setting) or 36V
• Amature 2 minute current rating (amps): 275
• Field 2 minute current rating (amps): 20
• KSI input current (typical):
  • 160 mA without programmer
  • 200 mA with programmer
• 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 1266 controller, including 5kΩ 3-wire potentiometers and 0–5V throttles
• Ambient operating temperature range: -40°C to 50°C
• Heatsink overtemperature cutback: starts at 85°C; cutoff at 95°C
• Heatsink undertemperature cutback: 50% armature current at -25°C

Feature 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
• 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
