详细介绍:
力士乐放大器是自动控制系统中的一个重要组成单元,和电动执行机构配套,组成比例式电动控制机构,可广泛用于电力、冶金、化工、轻工等工业部门的自动控制系统中。它可与DDZ-S系列电动执行机构配套, 也可作为一个通用单元,应用在其它类型的电动执行机构上。 与其它类型的伺服放大器比较,有如下特点: 1.电路采用智能控制系统对输入电流与反馈电流进行采样、比较,依据它们的差值大小对电机进行正反转控制。 2.系统对死区和精度进行自动调节,使控制品质最优。 3.也可手动调节死区大小以适应现场实际要求。 4.具有输入信号断路或小于一定值、位置反馈信号断路或小于一定值、反馈信号不跟随或反向变化大于一定值或固态继电器输出短路时,系统自动保护防止执行机构动作错误的功能以及开路报警、断电抱闸等功能。
力士乐放大器是用来控制伺服力士乐比例阀的一种型号放大器。
