GZDW-2 intelligent wall mounted DC power supply device
The GZDW-2 intelligent wall mounted DC power supply device produced by our company is an intelligent integrated cabinet power supply designed specifically for substations, switch stations, and user terminals. By adopting parallel current sharing technology, uninterrupted power supply maintenance can be achieved. Suitable for industrial and mining, petroleum, chemical, construction and other fields as well as user terminals, it can be used as the operating power supply and control power supply for high-voltage switches, relay protection automation devices. It can also be used
As a low-voltage backup power supply. The system is equipped with 4 lead-acid batteries, which have functions such as battery activation, battery detection, overvoltage and overcurrent protection.
Product Features
1. The battery has automatic activation detection and comprehensive system protection functions.
2、 The output current distribution is uniform and stable, ensuring balanced output of each battery and avoiding the impact of individual battery failures on the overall battery life.
3、 Parallel system, multiple parallel devices can achieve multiple backup solutions, making the power supply system more reliable.
4、 It can achieve continuous power maintenance and is easy to maintain. Moderate capacity, suitable for placing batteries in a single cabinet.
5、 The cabinet has a small volume and can be installed on the wall in narrow spaces.
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.
