5464-660  控制装置  用于正向或反向作用应用

基本细节:5464-660  控制装置  用于正向或反向作用应用

5464-660这些控制装置可用于正向或反向作用应用，也可用于单个或串联执行器。提供三种不同执行器电流范围的型号，以及高压型号(90至 150 Vdc或 88 至 132 Vac，45 至 440 Hz)和低压型号(20 至 40 Vdc)。高压型号在正面被标识为这样;低压模型则不然。在反向作用系统中，当执行器电压降低时，执行器需要更多的燃料。执行器的电压完全损失将驱动执行器充满燃料。
这允许备用机械球头调速器进行控制，而不是像直动式系统那样关闭原动机。
还提供可选的减速坡道。
当存在此选项时，从额定速度升温到总速的时间约为 20 秒。
如果此选项不存在，则会立即发生这种情况。
这些伍德沃德 2301A 控制器接受高压或低压电源。
低压型号的工作电压为 20 至 40 Vdc，高压型号的工作电压为 88 至 132 Vac 或 90 至 150 Vdc。
低压和高压型号都要求至少15 W 的功率容量。
除非绝对必要，否则请勿从控制柜中取出印刷电路板(PCB)如果必须从控制柜中取出 PCB，请遵循以下注意事项:请勿触摸 PCB 除边缘以外的任何部分。

5464-660 These controls can be used in forward or reverse action applications, as well as single or series actuators. Models are available in three different actuator current ranges, as well as high-voltage models (90 to 150 Vdc or 88 to 132 Vac, 45 to 440 Hz) and low-voltage models (20 to 40 Vdc). High-pressure models are identified on the front as such; Low pressure models do not. In a reverse-acting system, when the actuator voltage is reduced, the actuator requires more fuel. A complete loss of voltage in the actuator will drive the actuator to full fuel.
This allows the standby mechanical ball-head governor to be controlled, rather than turning off the prime mover as in direct-acting systems.
Optional deceleration ramps are also available.
When this option is present, the time to heat up from the rated speed to the total speed is about 20 seconds.
If this option does not exist, this happens immediately.
These Woodward 2301A controllers accept high or low voltage power supplies.
Low-voltage models operate at 20 to 40 Vdc, while high-voltage models operate at 88 to 132 Vac or 90 to 150 Vdc.
Both low and high voltage models require a power capacity of at least 15 W.
Do not remove the printed circuit Board (PCB) from the control cabinet unless absolutely necessary If you must remove the PCB from the control cabinet, follow the following precautions: Do not touch any part of the PCB other than the edges.
