高性价比伺服阀电流放大器
引言： 需要电流驱动的伺服阀与+/-10V电压控制输出的系统连接时需要一个电压-电流转换板。 虽然市面上这种板卡很多，但是真正专业生产这样的放大板的公司并不多见。DELTA的这个放大板，很好的适应了市场的需求。其高性价比得到了国内客户的认可。美国Delta公司的伺服阀放大器接收+/-10V电压信号将其转换为最大+/-100mA电流驱动伺服阀。 Delta 公司提供三种不同规格的电压电流转换器。 输出电流通过旋转开关可以设定，以10mA为间隔，从10mA开始一直设定到100mA的最大输出电流。多个通道可以并联以驱动更大电流的伺服阀。高速型转换器专门用于高动态性能系统。
