Description
YUKEN AME-D-10-100-20
Technical Specifications Power supply 24V DC; command signal input supports 0-10V voltage or 4-20mA current; output driving current range matched with proportional valve solenoid; built-in closed-loop feedback interface; operating temperature 0°C to +50°C; IP20 protection; adjustable gain, ramp and dead zone parameters.
Functional Features Receive external setpoint signals from upper industrial controllers. Convert setpoint signals into stable driving current for proportional hydraulic valve solenoids. Accept valve spool displacement feedback signal to form closed-loop control. Adjust response speed and output characteristics through internal parameter setting. Provide fault diagnosis of power supply, signal input and feedback circuit. Output alarm switch signal when abnormal state is detected. Support parameter setting and status viewing through dedicated debugging software.
Application Scenarios Injection molding machine hydraulic control, metal sheet stamping equipment, hydraulic press, engineering machinery proportional hydraulic system, material testing machine hydraulic loading control.
Performance Parameters High linearity of output current relative to input command; fast response of current regulation; low current ripple; stable closed-loop control accuracy for spool position.
Material Composition Internal PCB uses FR-4 flame-retardant multilayer circuit board; power drive chips are industrial power semiconductors; signal sampling chips are high-precision operational amplifiers; outer shell is aluminum alloy for heat dissipation; terminal blocks use nickel-plated copper contacts.
Structural Characteristics DIN rail mounting rectangular housing. Top and bottom wiring terminal blocks for power, command signal, feedback signal and alarm output. Internal aluminum base plate transfers heat generated by power devices. Front panel equipped with status LED indicators and parameter adjustment interface.
Working Principle The amplifier collects external control setpoint signal and spool position feedback signal, calculates the difference value between setpoint and feedback value through internal control algorithm, adjusts the output current of the power drive circuit, changes the electromagnetic force of the proportional valve solenoid, and controls the opening of the valve spool, so as to adjust the pressure and flow of the hydraulic circuit.
Installation Requirements Mount the amplifier on standard DIN rail inside the electrical cabinet. Wire 24V DC power, command signal cable and feedback signal cable to corresponding terminals. Set valve rated parameters, gain and ramp time in debugging software. Conduct no-load signal test before connecting to proportional valve. Adjust closed-loop parameters according to actual hydraulic response.
Precautions for Use Separate low-level signal cables from high-power hydraulic motor cables. Do not exceed the maximum output current of the amplifier. Ensure good cabinet ventilation for heat dissipation. Disconnect power before parameter modification and wiring change.
