GZDW Intelligent High Frequency Switching Power Supply DC System
GZDW intelligent high-frequency switching power supply DC system is a power supply screen designed specifically for users with different capacities. The system mainly consists of monitoring module, rectification module, AC/DC monitoring module, battery inspection module, etc. It is mainly used in small and medium-sized power plants, hydropower stations, various substations, and other users who use DC equipment (such as petrochemicals, mines, railways, etc.) in the power system. It is applicable to switch opening and closing, and instruments, meters, relay protection, and fault lighting in secondary circuits.
Product features

Are you Trading Company or manufacturer?
We are professional EV charger manufacturer.
How long does it take to full charge an EV?
This depends on the EV battery size, remaining battery capacity, and the type of EV charger used as well as environmental conditions such as temperature.Typically, an AC charger with an output power of 7–22 kW can fully charge an EV in between 3 and 6 hours.With a 50–200-kW DC fast charger, the charge time can be reduced to 10–60 minutes.
What’s the difference between AC and DC charging?
An AC charger provides AC power, which is then converted to DC power by an onboard charger inside the EV (before it reaches the battery). AC chargers are normally used in slow-charging applications such as home charging. A DC charger converts AC power from the grid into DC power, which is more efficient and supplies the batteries directly. Thus, the charging time is markedly shorter. DC chargers have higher power requirements and therefore a higher installation complexity. As such, the installation cost can be higher than that for an AC charger. DC systems are generally used in commercial/public charging applications where shorter dwell tines are needed
Which EV charger should I choose?
This depends on your situation. Fast DC chargers are ideal for cases where you need to recharge your EV quickly, such as at an intercity highway charging station or rest stop. An AC charger is suitable for places where you stay longer, such as workplace, shopping malls, cinema and at home.
