DC SepEx Motor Controller

Model 1244-6661, 48-80V, 600A

The supplied product, DC SepEx motor controller 1244-6661 is not the original CURTIS product. Fully compatible with CURTIS controller 1244-6661, this controller works with CURTIS handheld programmer 1313-4331, CURTIS PC Station programmer 1314-4402 and DALA handheld programmer.

Overview:

1244 MultiMode™ controllers are separately excited motor speed controllers designed for use in a variety of material handling vehicles. These programmable controllers are simple to install, efficient, and cost effective. Typical applications include low lifts, stackers, fork lifts, reach trucks, personnel carriers, counterbalance trucks, order pickers, boom trucks, and other industrial vehicles.

The 1244 MultiMode™ controller offers smooth, silent, cost effective control of motor speed and torque. A four quadrant, full-bridge field winding control stage is combined with a two quadrant, half-bridge armature power stage to provide solid state motor reversing and regenerative braking power without additional relays or contactors. The 1244 controller can also be specified to be compatible with CAN Bus communication systems.

The 1244-6661 controller is fully programmable via a CURTIS handheld programmer 1313-4331, CURTIS PC Station programmer 1314-4402 and DALA handheld programmer. The programming device provides diagnostic and test capability in addition to configuration flexibility.

Specifications:

• Model: 1244-6661 (fully compatible with CURTIS controller model 1244-6661)
• PWM operating frequency: 16 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• KSI input current (no contactors engaged):
  • 160 mA without programmer
  • 200 mA with programmer
• Logic input voltage: >7.5 V High; <1 V Low
• Logic input current: 10 mA
• Operating ambient temperature range: -40°C to 50°C
• Heatsink overtemperature cutback: 85°C
• Heatsink undertemperature cutback: -25°C
• Package environmental rating: IP64 / IP67

1244-6661 SepEx controller is designed for heavy duty electric vehicles applications, wildly applied in 48V, 60V, 72V and 84V DC power driving system. For more details, please read carefully the 1244 SepEx Controller Manual.

Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1244 SepEx Controller Manual before making the purchase.

Notice: By default, we will deliver the controller with default setting of 72V / 600A / 5k-0Ω. For better applying the controller to your system, the buyer should confirm with the seller the throttle type (0-5kΩ, 5k-0Ω or 0 – 5V, etc.).

Key Features:

• Norminal Battery Voltage (Volts): 48V, 60V, 72V and 80(84)V
• Amature Current Limit (amps): 600
• Amature 1 Minute Current Rating (amps): 600
• Amature 1 Hour Current Rating (amps): 140
• Field 2 Minute Current Rating (amps): 50
• Dimensions: L229xW178xH81 mm
• Net Weight: 3.9 kg

Features Include:

• Full-bridge field and half-bridge armature power MOSFET design, providing
  • infinitely variable forward, reverse, drive, and brake control
  • silent high frequency operation
  • high efficiency
• Regenerative braking, providing longer operation on a single battery charge and reducing motor brush wear and motor heating
• Programmability via the CURTIS handheld programmer 1313-4331, CURTIS PC Station programmer 1314-4402 and DALA handheld programmer
• Complete diagnostics through the programmer and the internal Status LED
• Two fault outputs provide diagnostics to remotely mounted displays
• Continuous armature current control, reducing arcing and brush wear
• Automatic braking when throttle is reduced from either direction; this provides a compression braking feel and enhances safety by automatically initiating braking in an operator hands off condition
• Deceleration Rate, Load Compensation, and Restraint features prevent downhill runaway conditions; speed is controlled to within approximately 20% of level surface value
• MultiMode™ allows four user-selectable vehicle operating personalities
• Programmable to match individual separately excited motor characteristics
• Meets or exceeds EEC fault detect requirements
• Vehicle top speed is controlled and limited in each mode
• Linear temperature and undervoltage cutback on motor currents; no sudden loss of power under any thermal conditions
• High pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startup
• Creep speed adjustable from 0% to 25% in each mode
• Continuous diagnostics during operation, with microprocessor power-on self-test
• Internal and external watchdog circuits ensure proper software operation
• Programmable coil drivers provide adjustable contactor pull-in and holding voltages
• Hour-meter enable output is active whenever the controller is providing motor current
• Optional Electromagnetic Brake Driver provides automatic control of an electromagnetic brake or other similar function
• Optional Reverse Signal Driver provides a low signal any time the vehicle is driving or braking in reverse
• Optional Auxiliary Driver provides a low signal to power an auxiliary contactor or other similar function
• Driver outputs are short circuit protected and provide built-in coil spike protection
• Controller is programmable to provide throttle control of motor speed, applied motor voltage, or motor torque
• Can be configured for CAN Bus compatibility

Other 1244 controller models are available:

• 1244-5561
• 1244-5564
• 1244-5565
• 1244-5651
