1. Power selection
The power of the distribution box can be customized according to the actual demand. The standards are 10kW, 20kW, 40kW, 60kW, 100kW, 120kw, 150KW, 160kW, 180kW, 200kW, 250KW, 300kW, etc
2. Output channel number selection
Under normal conditions, the cable from the distribution box to the panel is 3 * 2.5mm ², with single output current of 16a and single output power of 3.5kw.
10kW distribution box, 3-way output
20kW distribution box, output 6 channels
30kW distribution box, output 9 channels
40kW distribution box, output 12 channels
60kW distribution box, output 18 channels
80kW distribution box, output 24 channels
100kW distribution box, output 30 channels, and so on.
Of course, when considering the output wiring of air conditioner, fan and lighting, add the number of output channels
3. Selection of control mode (Reference)
The control modes include: time control, card multi-function card control, PLC control, APP / E cloud control, etc. which control mode should be selected?
Time control (the first generation): it is the most common, high quality and cheap. It can set more than 4 start-up and shutdown time periods every day. The time period from week 1 to Sunday can be different. The disadvantage is to change the time again. People need to enter the screen operation. Suitable for small indoor display screen
Time control (generation 2): in addition to the characteristics of the first generation, wireless (WiFi) control function, voice (voice) control function, smoke + smell + fire (sensor 3) protection function are mainly added
Multi function card control: it can start and close the display remotely, with temperature, humidity and brightness prompts. It is not convenient for joint control and multi control. Suitable for ordinary display
PLC full intelligent control (the first generation): the control of the screen is more comprehensive, which can be single control, multi-level joint control. Remote manual + time control + automatic control can be used to monitor the power consumption of the screen body, temperature + humidity and current + voltage of the screen body at any time. It can realize the central control, with 7 electric protection functions and LCD touch control. Suitable for small spacing display and large display
PLC full intelligent control (the second generation): in addition to the features of the first generation, it mainly adds overload protection function, voice control function, smoke + smell + fire light (sensor 3) protection function, which can be controlled on a large scale
Cloud control (APP / E) (the first generation): it can realize Internet control, LAN control and 4G network control. The mobile phone can control multiple electric cabinets at the same time, and the computer can control electric cabinets in different regions and cities at the same time
Cloud (2nd generation): in addition to the features of the 1st generation, it can record and query the operation conditions of different electric cabinets, including personnel operation records, alarm records and operation electric parameter records. Parameters can be stored in the cloud for a long time and printed at any time. It can be linked control and encrypted control of electric cabinets in all different regions, pre quote some potential hazards, and send them to the mobile terminal at the same time
4、 The difference of selecting distribution box between indoor panel and outdoor panel
The outdoor panel is generally installed on the roof, park, road and field. It is a certain distance from the control room. Therefore, it is recommended to select multi-function card control, PLC control or app / E cloud control anti type
Lightning protection, temperature protection, smoke protection, tripping protection, computer-side alarm, etc. shall be considered for outdoor panel
Indoor screen, can choose timing control, PLC control, simple and safe. It can be used in schools, swimming pools and places with large flow of people
Consider leakage protection, temperature protection, smoke protection, computer-side alarm, etc
