Model 1253 is a high-power hydraulic pump controller which provides both digital input and analog throttle based control of DC series wound motors. It features microprocessor based logic with programmable parameters and offers maximum flexibility for minimum cost.
FEATURES
Smooth, Silent Control
• Pulse-Width-Modulation control with programmable acceleration rates provides smooth application and release of pump motor torque.
• 15.6 kHz PWM frequency for near silent operation.
Programmable and Flexible
Easily programmable through the 1311 handheld programmer or 1314 PC Programming Station.
External Status LED output for easy system troubleshooting.
Four Speed Select inputs with individually programmable fixed speeds.
Programmable analog throttle input for precise speed control with a variety of signal sources.
Programmable turn-off delay allows SS4 input to be used for power steering. Adjustable minimum speed setting to maintain steering system pressure and pump lubrication.
Lift lockout input to disable the controller at low battery state of charge.
Seamlessly integrates with Curtis model 803, 906, 841, and enGage® IV displays for lift lockout functions.
Separate Interlock input to disable the controller when the operator is not present.

Product Description:
- CURTIS 1253-4804 Controller
- 48V DC Series Motor Controller
- Hydraulic Pump Motor Controller
- Upgraded Version of 1253-4803 / EVC255-4803
Key Features:- Curtis Model: 1253-4804 (EVC255-4804)- Norminal Battery Voltage (Volts): 48V 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 48V / 600A / 0-5kΩ.- For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1253 DC Series Motor Controller Manual before making your purchase.Features include:- Smooth and Quiet Control: Programmable acceleration rates provide smooth application of pump motor torque. 15.6 kHz PWM frequency for near-silent operation.- Programmable Flexibility: 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.Easily programmable through the Curtis Model 1313-4431 Handhold Programmer or 1314-4402 PC Programming Station.SPECIFICATIONS:- 1253-4804 CONTROLLERS:- Nominal input voltage: 48 V- PWM operating frequency: 15.6 kHz- Electrical isolation to heatsink (min.): 500 V- KSI input current (no contactors engaged): < 60 mA without Curtis Model 1313-4431 - Handhold Programmer; <130 mA with Curtis Model 1313-4431 Handhold Programmer- Logic input current: <1 mA- Status LED output current (max.): 5 mA- Throttle type: 2-wire 0 - 5kΩ, 2-wire 5kΩ - 0, or 0 - 5V- Storage ambient temperature range: -40°C to 85°C (-40°F to 185°F)- Operating ambient temp. range: -40°C to 50°C (-40°F to 122°F)- Package environmental rating: IP54- Weight: 2.6 kg (5.7 lb)- Dimensions (L× W×H) : 196 × 146 × 77 mmPackage List:- 1x CURTIS 1253-4804 DC Motor Controller Application Vehicle Example
CURTIS 1204M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1204M controllers are updated versions of the popular 1204 controllers, with the added functionality of being programmable-via the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.
CURTIS 1204M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.
