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. 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 programming device provides diagnostic and test capability in addition to configuration flexibility.

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, 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. 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 controProduct Description. 80V DC Series Motor Controller. Hydraulic Pump Motor Controller. Norminal Battery Voltage (Volts): 80V DC. By defaut, we will the controller of setting of 80V / 600A / 0-5kO (2-Wire Potentiometer Throttle). The Curtis 1253 provides a cost-effective solution for control of high power DC series-wound hydraulic pump motors. The 1253 accepts inputs from up to four Speed Select switches and also from an analog throttle. Its internal microprocessor-based logic controller provides maximum flexibility at minimum cost. Its performance characteristics can be tailored through an array of programmable parameters. Norminal Battery Voltage (Volts): 80V. Programmable Undervoltage Cutback (Volts): 54-70. Overvoltage Cutoff (Volts): 102. PWM operating frequency: 15.6 kHz. KSI input voltage: 28-60V DC. KSI input current (no contactors engaged). 60 mA without programmer. 130 mA with programmer. Logic input current. Status LED output current max. Heatsink overtemperature cutback: linear cutback starts at 80°C; complete cutoff at 120°C. Heatsink undertemperature cutback: 50% current below -25°C. Throttle Type: 0-5K O (default setting), 5K-0 O, 0-5V or single-ended 3-wire potentiometer (1kO to 10kO range). Dimensions: L196xW146xH77 mm. Net Weight: 2.6 kg. Storage ambient temperature range: -40°C to 85°C. Smooth and Quiet Control. Programmable acceleration rates provide smooth application of pump motor torque. 15.6 kHz PWM frequency for near-silent operation. Easily programmable through a Curtis programming device. Four Speed Select inputs SS1. SS4 with individually programmable top speeds. Programmable throttle input for precise speed control with a variety of signal sources. Programmable turn-off delay allows SS4 to be used for power steering. Adjustable minimum speed setting to ensure pump lubrication and to maintain steering system pressure. Robust Safety and Reliability. Interlock feature disables the controller when operator is not present. Programmable startup lockout prevents inadvertent operation. Seamless integration with Curtis gauges models 803, 841, 906, and enGage. IV for lift lockout function. Lift lockout disables the controller at low battery state of charge. Redundant watchdog timer circuits ensure proper software operation. External Status LED output for easy troubleshooting. Short-circuit protection on main contactor driver. Precharge control prevents pitting of contactor tips at startup. Thermal cutback provides protection to the controller. Rugged housing meets IP54 environmental ratings. Thank you for your support.
