基本細(xì)節(jié):5464-660? 控制裝置? 用于正向或反向作用應(yīng)用

5464-660這些控制裝置可用于正向或反向作用應(yīng)用，也可用于單個(gè)或串聯(lián)執(zhí)行器。提供三種不同執(zhí)行器電流范圍的型號(hào)，以及高壓型號(hào)(90至 150 Vdc或 88 至 132 Vac，45 至 440 Hz)和低壓型號(hào)(20 至 40 Vdc)。高壓型號(hào)在正面被標(biāo)識(shí)為這樣;低壓模型則不然。在反向作用系統(tǒng)中，當(dāng)執(zhí)行器電壓降低時(shí)，執(zhí)行器需要更多的燃料。執(zhí)行器的電壓完全損失將驅(qū)動(dòng)執(zhí)行器充滿燃料。
這允許備用機(jī)械球頭調(diào)速器進(jìn)行控制，而不是像直動(dòng)式系統(tǒng)那樣關(guān)閉原動(dòng)機(jī)。
還提供可選的減速坡道。
當(dāng)存在此選項(xiàng)時(shí)，從額定速度升溫到總速的時(shí)間約為 20 秒。
如果此選項(xiàng)不存在，則會(huì)立即發(fā)生這種情況。
這些伍德沃德 2301A 控制器接受高壓或低壓電源。
低壓型號(hào)的工作電壓為 20 至 40 Vdc，高壓型號(hào)的工作電壓為 88 至 132 Vac 或 90 至 150 Vdc。
低壓和高壓型號(hào)都要求至少15 W 的功率容量。
除非絕對(duì)必要，否則請(qǐng)勿從控制柜中取出印刷電路板(PCB)如果必須從控制柜中取出 PCB，請(qǐng)遵循以下注意事項(xiàng):請(qǐng)勿觸摸 PCB 除邊緣以外的任何部分。

5464-660

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.
