CURTIS 1244-5651 SepEx controller is designed for heavy duty electric vehicles applications, wildly applied in 36V and 48V DC power driving system. For more details, please read carefully the CURTIS 1244 SepEx Controller Manual.

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

Notice: By default, we will deliver the controller with default setting of 48V / 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.).
Norminal Battery Voltage (Volts): 48V (default setting) or 36V

Overview:

Curtis 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 1253 controller is fully programmable through a Curtis Model 1313-4401 Handhold Programmer  or 1314 PC Programming Station. The programming device provides diagnostic and test capability in addition to configuration flexibility.

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 through the 1313-4401 Handheld Programmer or 1314 PC Programming Station

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.
