80NH2GL is a special type of dual channel, hybrid-bi-directional current control module that has a range of applications, from providing current sensing and protection for high-power industrial motors, to electric vehicle traction and power supply systems, and uninterruptible power supplies (UPS). This versatile control module can also be used for other applications such as solar inverters, grid-interactive inverters, and motor driver applications.

The 80NH2GL is capable of running at a low thermal cut-off temperature of 20U degrees Celsius, and has a maximum operating temperature of 125U degrees Celsius, making it suitable for use in high temperature environments where reliability, durability, and efficiency is needed. Its main features include:

• High current superiority, which makes the module capable of controlling currents up to 600A
• High voltage endurable, allowing up to 500V continuous discharge
• A two-stage current control loop with an internal power module and separate current source/sink circuit
• An integrated PWM module with a frequency range of 150KHz
• Two digital-to-analog voltage limiters for output voltage control
• A built-in temperature sensor that can be used to monitor the module temperature
• A built-in power management unit that can be used to provide backup and redundant power

The 80NH2GL is designed to provide an efficient solution to controlling current in all kinds of motor applications by combining the two-stage current control loop with a dual-channel current control module which allows for less energy waste and improved torque control. The integrated PWM module also offers a high flexibility in terms of configuring the PWM Frequency to match the particular application requirements. Finally, the built-in temperature sensor ensures that the module always operate reliably and efficiently, while the integrated power management unit provides a redundant layer of protection in case of any sudden failures.

The 80NH2GL module is versatile and is suitable for many different types of motor applications. It can be used to control two-phase motors in applications such as electric vehicle traction systems, as well as three-phase motors in applications such as electric welding machines, CNC machines, generators, and pumps. The module can also be used to drive fans and compressors as well as for controlling the power supply and load of UPS, solar inverters, and grid-interactive inverters.

The working principle of the 80NH2GL is based on the two-stage current control loop and the dual-channel current control module. The two-stage control loop is composed of a PWM module and two digital-to-analog voltage limiters that provide the current and voltage control for the module. The two channels of the module are used to monitor and control the current flowing through each phase of the motor individually. They are equipped with analog feedback pins so that the module can adjust the output based on the current feedback from the motor.

The 80NH2GL module also features built-in protection circuits that help protect the module from overcurrent and overvoltage situations as well as from overloads. This module is designed to provide the best performance possible with its high-power capacity and superior monitoring and control features, making it an ideal choice for industrial applications that demand reliable power control and efficient operation.
