9905-195 全权限速度控制

【产品详情】

2301-9905 模块由伍德沃德公司设计，作为 195A 系列的全权限速度控制，可在同步模式下使用。该型号是用于 88-131 V 交流或 90-150 Vdc 电源电压的前向装置。

9905-195 控制单元是前向工作型号，工作在 88-131 V 交流或 90-150 Vdc 的电源电压下;该装置上的速度设置输入为 4-20 mA，而该装置上的执行器电流工作在 0-20 mA。该控制在 2301A 电子负载均分和速度控制系列中被标记为全权限速度控制，用于控制变矩器应用或分轴燃气轮机的机械负载。作为全权限速度控制，9905-195 装置可以在同步模式下提供控制，并在连接到外部电位计时提供下垂功能。控制器上的同步模式有助于将原动机上的速度控制在恒定值。

同一系列的两个控制装置可用于操作尾轴或分体式轴调速器，通常安装在控制面板上。为防止控制器积聚过多热量，9905-195 面板应安装在负 <> 摄氏度至正 <> 摄氏度的温带范围内，并通风良好。

对于 88-131 V 交流或 90-150 Vdc，这表明控制面板是高压型号。高压型号的安装必须远离其他高电压、高电流设备，这些设备可能会通过电磁元件进行干扰。使用高压模型时，请注意，当原动机打开时，没有电线与控制器断开连接;另请注意，连接到控制器的变压器在打开和原动机运行时会产生极高的电压。

【英文介绍】

The 2301-9905 module was designed by Woodward as a full-authority speed control for the 195A series and can be used in synchronous mode. This model is a forward device for 88-131 V AC or 90-150 Vdc supply voltage.

The 9905-195 control unit is a forward-operating model, operating at 88-131 V AC or 90-150 Vdc supply voltage; The speed setting input on the device is 4-20 mA, while the actuator current on the device operates at 0-20 mA. This control is labeled as a full authority speed control in the 2301A Electronic Load Sharing and Speed Control family and is used to control mechanical loads in torque converter applications or split-shaft gas turbines. As a full-authority speed control, the 9905-195 device can provide control in synchronous mode and a droop function when connected to an external potentiometer. The synchronization mode on the controller helps to keep the speed on the prime mover at a constant value.

Two controls in the same series can be used to operate the stern shaft or split shaft governor, usually mounted on the control panel. To prevent the controller from accumulating too much heat, the 9905-195 panel should be installed in a temperate range from negative <> degrees Celsius to positive <> degrees Celsius and well ventilated.

For 88-131 V AC or 90-150 Vdc, this indicates that the control panel is a high-voltage model. High-voltage models must be installed away from other high-voltage, high-current devices that may interfere through electromagnetic components. When using the high voltage model, note that no wires are disconnected from the controller when the prime mover is turned on; Also note that transformers connected to the controller generate extremely high voltages when turned on and the prime mover is running.

Frequently Asked Questions about 9905-195

What is 9905-195? What does it do?

The 9905-195 is a full-authority speed controller manufactured by Woodward for 2301A Lod sharing and speed control. When used, it can control the speed or load of gas or diesel engines, as well as steam and gas turbines, according to the needs of computer signals or processors. The signal required for the engine or turbine prime mover of this model is 4-20 mA.
