力士乐比例放大器内部全部采用贴片工艺生产，进口元器件,增强了抗干扰性能；集成度高，体积小巧，结构紧凑，除了调节元件，其它均不外露，避免金属件脱落造成短路；内部采用特殊功率器件、优化的电路设计，温升低，摒弃了笨重的散热片；标准导轨放大器为标准导轨安装式，用于驱动两个电磁铁比例阀。放大器对电磁比例阀提供所需电流以校准阀的调整量，使之与输入信号相对应。该放大器用于开环控制系统。放大器通过对电磁铁提供一切换电流，使阀的调整与输入信号（电压或电流）成比例。为保证阀的调整精度，可用放大器上的电位器调整增益和偏流。供给放大器的输入信号通常是由外界电位器或PLC控制单元提供。放大器由斜坡发生器、偏流调整、增益调整、PWM调制、使能控制以及保护电路组成，电流调节范围0-3安，负载阻抗2-45Ω。安装，拆装方便；
