HE42BU/12

HE42BU/12 is a type of variable frequency drive (VFD) specifically designed for usage in hazardous environments. This VFD is designed to control electric motors in hazardous area applications such as petrochemical plants, off-shore oil rigs, locomotive traction, etc. The HE42BU/12 is certified for safe installation and operation in such hazardous environments and is praised for its high performance and maximum safety features.

The HE42BU/12 variable frequency drive consists of two main sections: the main drive unit and the power section. The main drive is the brains of the VFD and is responsible for receiving and processing the signals received from the operator’s terminal. The power section is responsible for taking the signals received from the main drive and transferring them to the motor. The power output of the HE42BU/12 can be adjusted to levels between 4-12 Amps.

The HE42BU/12 is suitable for general motor control applications, such as in cranes or conveyors. The VFD has a wide-ranging operating frequency between 0.5 and 600 Hz and is able to handle up to 50 HP motor ratings. It also has both high and low speed settings for controlling motor speed. It also features a dynamic torque boost system that helps to maintain the torque output of the motor at low speeds.

The HE42BU/12 also has several safety features to protect against overvoltage, undervoltage, motor overload, excessive temperature, etc. It also features variable speed control for better motor control, such as speed ramping and dynamic braking. There is also a logic inputs feature that can be used to program the motor parameters.

The working principle of the HE42BU/12 is relatively simple. When the variable frequency drive receives an input signal from the operator’s terminal, it adjusts the power output to the motor according to the desired speed. The speed of the motor can be adjusted using the variable frequency drive by changing the frequency of the electric signal to the motor. The frequency of the electric signal is directly proportional to the speed of the motor.

The HE42BU/12 variable frequency drive is a reliable and highly accurate VFD, suitable for tackling the most demanding operations in hazardous areas. Its wide range of features and safety certifications make it an ideal choice for industrial motor control applications, where maximum safety and efficiency are paramount.
