Comparison of AC and DC charging methods
The main types of charging for electric vehicles (EVs) are alternating current (AC) and direct current (DC), which differ in terms of efficiency, speed, and impact on the grid. The following is a deta
• For automatic switching between normal and standby power supplies.
• Relay the work voltage range from 120v to 280v,
it can still work,not appear coil burned phenomenon.
• Small size, with firefighting, power generation and other functions.
• Strong anti-interference ability Quick Transfer reliable performance.
