Advantages and features of Vickers amplifiers
Wide input compatibility and high-precision output
Supports differential input (±10V) and wide voltage signal compatibility, input impedance up to 10MΩ, significantly reducing the impact of signal source load.
The output current can reach 2A, and the output voltage range is ±20V when the load is ≥1kΩ, meeting the needs of high-frequency signal processing (bandwidth 500kHz).
Intelligent control function
Integrated adjustable gain (20dB to 60dB), dead zone compensation and dither (jitter) functions to optimize the control accuracy of proportional valves.
Supports digital gain adjustment interface (SPI/I²C), which is easy to integrate with industrial control systems and simplifies control logic.
Modularity and compatibility
Adopts plug-in design, built-in proportional amplifier board, reduces the need for external control components, and reduces system complexity.
Adapts to a variety of control signals (0-10V, 4-20mA), compatible with Vickers full range of proportional valves and solenoid valves.
Multiple protection mechanisms
With short circuit protection, reverse polarity protection and overcurrent/overvoltage protection, the system operation safety is improved.
Fully enclosed IP67 protection design, resistant to harsh industrial environment (-40℃ to 85℃).
Energy-saving and long life
Low harmonic distortion (THD <0.01%) and high power supply rejection ratio (PSRR 120dB) reduce energy consumption and signal interference.
MTBF (mean time between failures) exceeds 100,000 hours, reducing maintenance frequency and cost.
Precautions for use
Heat dissipation and power supply configuration
When continuous high power output is required, a heat sink must be installed to ensure that the chip temperature is ≤125℃4.
Dual power supply ±15V is recommended to avoid limited dynamic range due to single power supply.
Signal and wiring specifications
Signal lines must be shielded separately and grounded in accordance with regulations to prevent electromagnetic interference from affecting control accuracy58.
Wiring must be strictly in accordance with voltage specifications (such as 12V/24V). Long-distance transmission requires increased wire diameter or voltage regulator.
Parameter debugging and calibration
For the first use, the Pro-FX software needs to be used to calibrate the gain, dead zone compensation and other parameters to match the system requirements.
Check the gain accuracy regularly (recommended every 6 months) to avoid deviations caused by component aging.
Environment and protection requirements
Avoid using in environments with strong vibration or high dust concentration to prevent internal components from loosening or contamination.
High temperature conditions require shortening the maintenance cycle and regularly checking the status of seals and connectors.
Maintenance and fault prevention
It is recommended to rotate the spare amplifier to prevent capacitor aging or poor contact due to static conditions.
When the output signal is abnormal, prioritize checking the power supply stability and signal line shielding integrity.
Summary
Vickers amplifiers are suitable for high-precision scenarios such as medical equipment and industrial automation with their core advantages of wide signal compatibility, intelligent control functions and high protection levels. When using them, you need to focus on heat dissipation design, power supply configuration and regular calibration to ensure long-term stable operation.
