Description of Product

7KW DC Charging Pile

This is a 7KW DC charging pile. It uses a single - phase L/N + PE input system, with an input voltage range of 176 - 264VAC, a frequency of 50/60Hz, and a maximum input current of less than 34A. The maximum output power is 7KW, and the power can be adjusted from 3.5KW to 7KW via software control. The output current ranges from 0 - 20A, and the voltage is 250 - 750VDC, with a constant - power output range. It has voltage and current regulation functions, both with an accuracy of less than ±1%. The operating temperature ranges from - 40°C to +75°C, and derating is required above +55°C. It adopts forced air cooling, with a relative humidity not exceeding 95% and no condensation. Derating is needed when used at altitudes above 2000 meters, making it suitable for various environments.
