Working Principle

Material & Structural Characteristics

• Main circuit board: FR-4 flame-retardant PCB with surface-mount power semiconductor components
• Outer housing: ABS flame-resistant industrial plastic black enclosure with vertical ventilation slots
• Adjustment components: Sealed dust-proof rotary potentiometers with metal adjustment shafts
• Wiring terminals: Screw-type brass terminal blocks with anti-loosening spring washers for power, input, and load wiring

Core Advantages & Highlights

1. Differential input circuit delivers superior noise rejection in heavy industrial hydraulic machine environments
2. Adjustable dither amplitude eliminates proportional valve hysteresis for ultra-precise flow/pressure regulation
3. Full overcurrent and short-circuit protection prevents permanent proportional solenoid coil damage
4. Front-panel accessible tuning potentiometers enable on-site hydraulic loop response calibration without disassembly
5. Optimized circuit design exclusively matched to 10 Ω standard YUKEN proportional valve coils

Applicable Industries

Installation Mandatory Requirements

1. Mount vertically inside hydraulic control cabinet with minimum 20 mm top/bottom ventilation clearance
2. Separate high-current valve load wiring from low-level analog command signal wiring by minimum 15 cm distance
3. All analog command wiring must use shielded twisted-pair cable with single-point shield grounding
4. Install mains surge protection device on the AC 100 V power input terminal to suppress grid voltage transients
5. Complete gain and ramp time calibration after full wiring connection before hydraulic system pressurization

Operation & Maintenance Precautions

1. Do not connect solenoid coil loads with resistance values outside the 9–11 Ω design operating range
2. Keep amplifier housing free of hydraulic oil mist contamination to prevent internal circuit short-circuit failure
3. Avoid ambient humidity exceeding 80% non-condensing to prevent PCB trace corrosion
4. Disconnect AC 100 V mains power before adjusting front-panel calibration potentiometers
5. Replace internal power switching semiconductors immediately upon persistent overcurrent fault activation
