CURTIS DC SepEx Motor Speed Controller

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

Specifications:

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

With a transfer connector (convert kit), the 1266A-5201 can easily replace the 1510A-5251 SX (Seperately Excited or SepEx) motor speed controller (Part Number 102806201, CURTIS Model Number 1510A-5251). The two controllers have the same installation dimension.

We supply the converter for 1510A-5251. When you buy a controller 1266A-5201 with convert kit, we will reprogram the controller for obtaining the same configuration of a 1510A-5251.

For more details of replacement of the controller 1510A-5251, please contact us.

For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1266 Controller Manual (PDF format) and 1266 Controller Datasheet (PDF format) before making the purchase.

By default, we will deliver the controller with default setting of 48V / 275A. Various throttles can be used with the 1266A-5201 controller, including 5kΩ 3-wire potentiometers, 0–5V throttles, and electronic throttles. For more controller parameter details, please take a look at the 1266A-5201 controller default setting parameter list.

For activating the 1313-4331 Handheld Programmer or 1314 PC Programming Station, J1-8 and J1-16 terminals should be connected to "B+" of DC power source (minimum 16.8V, maximum vehicle system voltage); "B-" busbar should be connected to "B-" of DC power source (minimum 16.8V, maximum vehicle system voltage).

Notice: We supply also the 1266A-5201 controller assemblage with throttle (foot pedal).

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 Features:

• CURTIS Model: 1266A-5201
• Norminal Battery Voltage (Volts): 36V / 48V
• Amature 2 minute current rating (amps): 275A
• Field 2 minute current rating (amps): 20A
• 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
• Package environmental rating: IP5X
• Dimensions: L198 × W114 × H68 mm
• Net Weight: 1.9 kg

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
