CURTIS 1253-8001 Motor Speed Controller DC 80V Programmable PMC Forklift Pump
CURTIS 1253-8001 Controller
80(72-84)V DC Series Motor Controller
Hydraulic Pump Motor Controller
- Curtis Model: 1253-8001 (HELI / HANGCHA Model: EVC255-8001)
- Norminal Battery Voltage (Volts): 80(72-84)V DC
- The buyer should confirm with the seller the battery system voltage and the throttle type (0-5kΩ, 5k-0Ω or 0-5V).
- By defaut, we will the controller of setting of 80V / 600A / 0-5kΩ (2-Wire Potentiometer Throttle).
Notice: By default, we will deliver the controller with default setting of 80V / 600A / 0-5kΩ. 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.)

- 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 Model 1313-4431 Handhold Programmer or 1314-4402 PC Programming Station. The programming device provides diagnostic and test capability in addition to configuration flexibility.
