A800D

双通道高压线性放大器

双通道高压线性放大器

概述

Pendulum Instruments双通道高压线性放大器 A800D 包含两个独立的 A800 放大器，它们共享公共接地参考和电源。该装置具有100倍的固定放大倍数，能够输出±400V的双极性高电压。幅度±4 V的信号源可用作输入器件，输入幅度通常应保持在±4 V以内。A800 高压线性放大器配有额定电流为 15 mA 的微保险丝，如果输入电压超过最大值的 500%，该微保险丝将被熔断。

放大器的最大速度（转换速率）取决于负载，如果放大器在其输出电流限值内工作，则其速度（转换速率）为500 V/us，这是A800系列放大器的标准设置。

连续输出电流限制为60 mA，输出功率限制为约30 W。当负载需要超过60mA电流时，放大器将相应地降低输出电压，以保持电流在限制范围之内。
