variable frequency

基本解釋

So, NIRVANA can say is the only true sense have speed of variable frequency drive screw air compressor.
所以，NIRVANA可以說是目前惟一真正意義上擁有調速變頻敺動的螺桿空壓機。
Such as variable frequency drives can be further connected directly to the communications network or hardwired if necessary.
例如變頻敺動器如果有必要的話可以直接被連在通訊網(wǎng)絡或硬線上。
A variable frequency inverter with a RS-485bus communication interface is designed. It has the advantages of simple hardware interface and high reliability of communication.
設計了一種帶有RS-485接口的交流變頻控制器，它硬件接口簡單，通訊可靠性高。

For example, rather than purchase expensive ultra-efficient motors, low cost opportunistic additions to old fans and pumps such as variable frequency drives and demand controls can deliver equal energy savings at a fraction of the cost.
