變頻電箱 變頻調(diào)速控制箱由斷路器、交流接觸器、按鈕、指示燈、變頻器、調(diào)速旋鈕、顯示儀表等組成。具有優(yōu)異的調(diào)速性能和顯著的節(jié)能效果，尤其在風機、水泵上使用，其節(jié)能效果更為突出（一般情況下，速度降低20%，節(jié)能可達50%）輸入電壓：單相220V和三相400V可選。 調(diào)速范圍：0~300Hz（視電機而定，一般不超過電機額定頻率）。 控制方式：現(xiàn)場控制、遠程端子控制、多段速控制、模擬量控制等。 顯示參數(shù)：轉(zhuǎn)速、電流電壓、率等。
廣泛適用于各種場合風機、水泵使用，可實現(xiàn)節(jié)能、無級調(diào)速、軟啟動、軟停車、對機械和電網(wǎng)無沖擊和延長機械壽命等作用。并可按客戶要求采用遠程、壓力、溫度、時間控制等多種操作控制方式。

Frequency conversion electric box The variable frequency speed control box consists of circuit breaker, AC contactor, button, indicator light, frequency converter, speed control knob and display instrument. It has excellent speed regulation performance and remarkable energy saving effect, especially on fans and water pumps, its energy saving effect is more prominent (generally, the speed is reduced by 20%, energy saving can reach 50%). Input voltage: single phase 220V and three Phase 400V is optional. Speed range: 0~300Hz (depending on the motor, generally does not exceed the rated frequency of the motor). Control mode: field control, remote terminal control, multi-speed control, analog control, etc. Display parameters: speed, current and voltage, rate, etc.
It is widely used in various occasions for fans and pumps. It can achieve energy saving, stepless speed regulation, soft start, soft stop, no impact on machinery and power grid and prolong mechanical life. Remote control, pressure, temperature, time control and other operational control methods can be used according to customer requirements.
