变频调速控制箱
产品概述:变频调速控制箱由断路器、交流接触器、按钮、指示灯、变频器、调速旋钮、显示仪表等组成。具有优异的调速性能和显著的节能效果，尤其在风机、水泵上使用，其节能效果更为突出（一般情况下，速度降低20%，节能可达50%）输入电压：单相220V和三相400V可选。 调速范围：0~300Hz（视电机而定，一般不超过电机额定频率）。 控制方式：现场控制、远程端子控制、多段速控制、模拟量控制等。 显示参数：转速、电流电压、率等。
适用范围:广泛适用于各种场合风机、水泵使用，可实现节能、无级调速、软启动、软停车、对机械和电网无冲击和延长机械寿命等作用。并可按客户要求采用远程、压力、温度、时间控制等多种操作控制方式。 -
Frequency control box
Product Overview: 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.
Scope of application: 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.
