Detailed introduction of digital display intelligent temperature controller
feature Precise temperature control: Using high-precision temperature sensors and advanced control algorithms, it is possible to accurately measure and control temperature, and the temperature control accuracy can usually reach between ± 0.1 ° C and ± 1 ° C. Digital display: Equipped with a clear digital display screen, the current temperature value is visually displayed […]
Soft starter for single-phase motor working principle
The soft starter uses a thyristor as a voltage regulator and is connected in series between the power supply and the controlled motor. By controlling the conduction Angle of the thyristor, the input voltage of the motor is gradually increased from zero to the preset function relationship until the end of starting, and the motor […]
Bypass soft starter in detail
Working principle When starting, the soft starter is connected to the motor circuit, and gradually increases the output voltage by controlling the on-angle of the thyristor, so that the motor current slowly rises from zero, so as to realize the smooth start of the motor and reduce the impact of the starting current on the […]
Soft starter for single-phase motor
action Reduce the starting current: When the single-phase motor is directly started, the starting current is usually large, which may cause an impact on the power grid, resulting in voltage fluctuations, affecting the normal operation of other equipment. By gradually increasing the input voltage of the motor, the soft starter makes the motor starting current […]
Detailed introduction of 37kW soft start cabinet
Working principle Voltage ramp start mode: In the early stage of the soft start cabinet, by controlling power electronic devices such as thyristors, the output voltage rises slowly according to the preset ramp curve, gradually increasing from the lower voltage to the rated voltage of the motor. The motor current also gradually increases, avoiding the […]
Inverter secret
6. How many meters below the highest installation elevation of the frequency converter in the plateau area? Generally, the frequency converter is marked to be installed below 1000m above sea level 7. What is inverter overcurrent? Overcurrent refers to the frequency converter overcurrent. That is, the output current of the inverter or the current of […]
Seg 300 bypass soft starter
Performance characteristicsSoft start function: Through the use of voltage reduction and other technical means to achieve the smooth start of the motor, to avoid the starting current on the power grid and the motor itself caused a large impact. Effectively reduce the starting current, reduce the impact on the power grid, so that the power […]
Inverter
Frequency converter is a power electronic device, mainly used to change the supply frequency and voltage of AC motor, so as to control the speed and output power of the motor. Inverter is widely used in various industrial automation control systems, such as fan, pump, compressor, conveyor belt and other equipment speed control. At the […]
Soft starter 4 advantages
Various startup modes Soft starting technology has a variety of starting methods, so that the relevant staff can choose the corresponding starting method according to the actual situation, so as to flexibly start the motor, avoiding the fixed nature of traditional starting technology. In addition, the soft start technology is more flexible and changeable, and […]
