What are the main differences and functions between DC screen and AC screen? 

These are all things we need to consider, so what are the specific circumstances? 

1、 Different definitions. AC distribution panel (referred to as AC panel) is a branch switch control distribution cabinet composed of voltmeter, ammeter, switch (or automatic switch), fuse, signal light, circuit, etc., according to different electrical equipment and different electricity consumption. It can monitor the total voltage, current or branch voltage and current usage in the entire power system, and switch branches according to the required situation. The DC screen is mainly used to provide DC power to high-voltage switching mechanisms, control systems, comprehensive protection, instrumentation, and emergency lighting.

 2、 Output is different. The input power of both the AC screen and the DC screen is AC power, but the output is different. The AC screen outputs AC power, while the DC screen outputs DC power. After an AC power outage, the AC screen does not output, but the DC screen can still output DC power. 

3、 Different properties: The AC screen is essentially a low-voltage distribution cabinet, with AC input and output, usually matched with the DC screen to provide power distribution for the DC screen and distribution room; The DC screen converts AC into DC to charge the battery. When there is a power outage in the city, the battery pack supplies power to the high-voltage switching mechanism, control system, and comprehensive protection system through the bus.

4、 Different uses: The function of the communication screen is to display the operating status of various high and low voltage distribution cabinets. Generally, there are current and voltage displays, as well as opening and closing indicators on it.
