High quality Curtis DC Motor 48V-96V circuit Controller With Robust Reliability

Product Description

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

Feature 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 1313-4431 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
