电压放大电路板

我们所有的功放板是设计为可以集成到桌面式驱动机箱内,并且在-20/ +150V范围内来驱动压电促动器。我们提供两种放大器:线性放大器或开关功率放大器。

我们也提供嵌入式应用的OEM功放板

压电促动器的线性放大器系列

这系列包括CA45独立放大器和LA75系列功放板。线性放大器是最常规的解决方案来驱动压电促动器。它们被用于容性负载驱动,如压电促动器,噪声极低。

压电促动器的开关功率放大器系列

开关功率放大器可以对压电促动器执行线性连续状态或者纯开/关状态,致动速度非常快。该SA75D是目前市场上在连续模式下最强大的放大器。该SA75系列是新型高功率放大电路板,用于那些要求高无功功率应用(防震,疲劳试验,加工等)如航空,材料科学和生产应用。在压电负载的特殊的拓扑结构中使用高频的PWMSA75提供在连续模式下的高功率和非常低的纹波。这些特殊的功能使SA75放大器非常适合驱动高电容负载,如强大的LXL压电促动器。对于并行测试台的特殊配置,可以通过多通道输出配置来获得。

SP75系列是一个有2个状态的驱动板。它集成了逻辑输入易于编程。
