ZJKD Special power supply for special equipment
ZJKD Special power supply for special equipment
▲ZJKD Special power supply for special equipment
The special power supply for special equipment adopts soft switching power supply technology, which is suitable for high-power mobile DC power supply system with high power density and strong overload capability, which facilitates migration between different work sites. The surface of the power supply shell is treated with special anti-corrosion and water-repellent treatment, and its integrated internal (full-sealed) integrated structure makes the power supply resistant to extreme environments such as humidity, corrosion, mold, salt spray, vibration shock, high heat and cold. strong ability. Easy to install and connect, output voltage and current can be customized according to user requirements.
