III. Product Features

1. Energy Efficiency and Environmental Protection

The module operates with high efficiency across the full load range, with a full-load efficiency exceeding 96%. It also features ultra-low standby power consumption, effectively reducing energy consumption. This not only saves costs but also contributes to environmental sustainability.

2. Ultra-Wide Input and Output Ranges

• AC Input Range: The wide AC input voltage range of 260Vac – 530Vac allows it to adapt to various grid environments. Whether in areas with unstable voltage or different grid standards, the module can operate stably.
• DC Output Range: The DC output voltage range of 50Vdc – 1000Vdc meets the rapid charging requirements of multiple types of electric vehicles and battery packs. It can flexibly adjust to different battery voltages for efficient charging.

3. Wide Constant Power Output

Achieving constant power output within the range of 300Vdc – 1000Vdc ensures stable charging for various electric vehicles during fast charging. This stable power supply helps protect the battery and improve charging efficiency.

4. Low-Voltage High-Current Output

Below 300Vdc, the module can maintain a maximum output of 133A, satisfying the fast charging needs of more devices. This feature makes it suitable for a wider range of applications, including some special electric vehicles or equipment with high current requirements.

5. High Power Density

With a power density greater than 65W/in³, the module saves space inside the charging pile, reduces the  it occupies, and lowers construction costs. This is crucial for the compact design of modern charging piles.

6. Safety and Reliability

• Emergency Stop Function: It can quickly respond to emergency stop commands of the system, ensuring the safety of the charging process. In case of any emergency, the module can be stopped immediately to prevent potential hazards.
• Multiple Protection Functions: The built-in discharge circuit automatically discharges residual charges, and the battery backflow protection function effectively protects the battery, ensuring the reliable and safe operation of the system. These protection measures enhance the overall stability and safety of the charging process.
• Intelligent Air Duct Detection: It intelligently detects the smoothness of the system air duct. When the air duct is blocked, it automatically limits power and gives an alarm, improving equipment reliability. This helps prevent overheating and other issues caused by poor air duct conditions.
• High Environmental Reliability: Key circuits are treated with glue coating, significantly improving performance in terms of salt spray prevention, moisture resistance, and mildew resistance. The module can adapt to various harsh environments, ensuring stable operation in different climatic and environmental conditions.

7. Low Noise

The module offers three noise mode settings to meet noise control requirements in different environments, providing users with a quiet usage environment. This is especially important for charging piles installed in residential areas or noise-sensitive locations.

8. Intelligent Monitoring and Convenient Operation

• It can output corresponding DC voltage/current according to different monitoring settings, providing flexible charging control.
• The fan speed reporting function allows users to adjust the fan speed of the entire charging pile according to the module’s fan speed, further optimizing noise. This intelligent operation improves user experience and system efficiency.

IV. Working Mode

Low-Voltage Mode

When the monitoring system sets the module to low-voltage mode, the module operates fixedly in this mode. In this mode, it can output a maximum voltage of 585V and a maximum current of 133A. When the monitoring system sends a voltage command exceeding 585V, the module will not respond, ensuring stable operation within the set low-voltage range.

V. Product Principle

The internal circuit of the SEG1K0135S2 charging module is mainly divided into two parts. The first part is responsible for rectifying the wide-range three-phase AC input voltage into an internal high-voltage bus and completing the correction of indicators such as PF and THD. The second part is responsible for converting, isolating, and rectifying the internal high-voltage bus, and outputting corresponding DC voltage/current according to different monitoring settings.

Choosing the SEG1K0135S2 charging module from Imax Power means choosing an efficient, safe, and reliable electric vehicle charging solution. We are committed to providing high-quality products and services to create a green travel future together with you.
