48V 600amp electric forklift programmable DC series motor speed controller with Pump, model: P153-4804

The CURTIS 1253-8001 provides a cost-effective solution for control of high power DC series-wound hydraulic pump motors. Its system integration features are designed primarily for Class I and Class II material handling vehicles. Typical applications include the pump systems of material handling trucks (counterbalance trucks, reach trucks), aerial lift platforms (scissor lifts, articulating/telescoping booms), and other industrial vehicles.
The 1253-8001 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.

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.
Easily programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
