The total system is composed of four subsystems: AC power subsystem, DC power subsystem, inverter power subsystem, and communication power subsystem, each subsystem is composed of an independent configuration menu and a real-time data query menu. The size of each subsystem is affected by the total system configuration, so the size of the subsystem must be configured in the total system configuration menu to make detailed parameter configuration for the subsystem. For example, if the number of AC screens is set to 0 in the total system maintenance configuration, the AC subsystem will not be able to enter the AC subsystem for configuration, and the AC subsystem will not have the monitoring function. Because the configuration of the master system is related to the data structure of the whole system, if the maintenance level parameters of the master system are modified, the restart must take effect.

Equipped with a 7-inch large-screen color LCD touch screen, it can query the voltage, current, frequency, active power, reactive power, electricity, harmonics and other power quality status of each main and branch circuit at any time, and can record the load curve changes in real time, as well as the redundancy ability of the system in the event of partial failure

UPS incoming and outgoing power distribution cabinets all adopt Hailian's new GDH NR system, flexible cabinet structure, easy to realize cabinet combination, parallel installation between cabinets, etc.

The inlet and outlet lines of the UPS outlet cabinet are all Schneider NSX series molded case circuit breakers, and the thermal-magnetic trippers are selected, and the upper and lower levels of the circuit breakers are selectively coordinated.

It further integrates the company's new research and development achievements in recent years, especially the multi-loop electric energy metering and monitoring technology, circuit breaker hot swap and phase modulation technology, and large-screen LCD touch screen technology, so that the function of the precision power distribution cabinet is increasingly perfect

Usually, the lighting of the data center is bright, and there are no lighting windows and no suspended ceilings, but the accuracy of the computer room is very high. Therefore, in addition to considering the energy metering control to achieve the purpose of efficient use, the continuity of lighting is also required.

The function of the emergency lighting distribution box is to supply power to the emergency lighting and evacuation indication lighting circuit in the event of an accident (including fire situation).

The UPS3000 LTD3000 series three-in, three-out integrated power distribution integrates UPS power supply, IT power distribution, air conditioning power distribution, lighting power distribution, ATS power supply, UPS input, UPS output, UPS bypass, and UPS maintenance bypass power distribution into a power distribution cabinet through a combination of technical means, realizing the safety, reliability, easy maintenance, and high integration density of the power supply and distribution system, and providing a safe, reliable, stable, and efficient green power supply system for the data center.
