CURTIS Controller 1253-4804 Controller with High Efficiency

The CURTIS 1253 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 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.

The 1253 controller is fully programmable through a CURTIS 1313-4331 Handheld Programmer or 1314 PC Programming Station. The programming device provides diagnostic and test capability in addition to configuration flexibility.
