The CJ688TGEI-C is one of the latest models of Coulomb\'s law variable-frequency drive (VFD). Its advantages include a smaller size than other models, full digital control, low power consumption, high efficiency, and a high level of programming flexibility. In this article, we will discuss the application fields and working principle of this VFD.

Developed by Coulomb Technologies, the CJ688TGEI-C is designed to control the speed of three-phase asynchronous motors. It can be used in a variety of applications, including HVAC, pumps, and conveyors. Moreover, it is suitable for controlling large and medium-sized motors.

Despite its small size, the CJ688TGEI-C offers excellent features. It has several preset programs, which allow users to quickly adjust the speed of the motor. It also provides a number of protection features, such as an under-voltage protection, overload protection, and linear output current protection. The CJ688TGEI-C also has an additional feature, which is an adjustable motor reversing switch.

The basic operating principle of the CJ688TGEI-C is simple. It uses pulse-width modulation (PWM) to control the motor\'s speed and torque. This is done by varying the frequency of the PWM signal, which in turn causes the motor to run at different speeds. The PWM signal is generated using a microcontroller, which receives input from a variety of sensors and switches.

The CJ688TGEI-C is a great choice for various applications. It is easy to install and operate, has a long life expectancy, and is highly energy efficient. Moreover, it has a wide range of protection features and can be programmed to operate in various modes. This makes the CJ688TGEI-C an ideal choice for a wide variety of applications.
