SANDI SERIES charging module is for electric vehicle charging station. With single-phase non neutral conductor AC input, it has the advantages of high efficiency, high power density and low harmonic. Functional details 1. Hot plug Plug technology is applied to the charging module to provide convenience for installation and maintenance. The access of the charging module to the system shall not disturb the output voltage of the system. 2. Advanced current sharing technology Under constant voltage working mode, the charging modules can share current automatically within 10S, with degree of unbalance less than �±0.5A. 3. Control of input limited power Refer to Fig. 1-10 for the relation between the output power and input voltage of the charging module. When the input voltage is within 360 Vac ~ 450 Vac (return difference is less than 5V), the module can output the maximum power of 20 KW; when the input voltage is within 260 Vac ~ 320 Vac, the module can still work normally under limited power mode. 4. Control of output constant power When there is a rated input voltage, the output power of the module is 20 KW. Refer to Fig. 11 for the relation between the output voltage and the output current of the module. The SD75050 module uses two operating modes with output voltage ranges of 50 to 750V. The module only selects the operating mode based on the value of the received demand voltage, and does not select the operating mode based on the actual output voltage. 5. Temperature limited power 6. Regulation of output current limiting point 8. Regulation of output voltage The output voltage of the module can be regulated constantly through the external monitoring module, with regulation range of 50Vdc ~ 750Vdc and minimum regulation step of 0.1 Vdc. 9. Fan control The built-in processor of the module can regulate the speed of the fan according to the internal temperature and output current of the module. 10. Protection of input overvoltage/ voltage shortage 11. Output overvoltage protection The overvoltage protection point is 260Vdc ~770Vdc (�±10 Vdc). Default is 778Vdc.The module can be started after manual intervention upon overvoltage protection. 12. Over-temperature protection The environmental over-temperature protection point is 80�°C. When the DC panel has a temperature over 100�°C, the module will stop working; when the DC panel has a temperature below 90�°C, the module will automatically work again. 13. Protection of internal bus fault When the internal bus voltage of the module is beyond the overvoltage/ voltage shortage protection point, the module will be powered off automatically. At this time, there is no output from the module and the fault indicator light is on. 14. Short circuit protection In case of short circuit of the module, it will be subjected to protective shutdown and the red indicator light of the panel is on, and this condition will be transmitted to the monitor of the "module fault".

The cable design conforms to the requirements of national standard GB/T12706-2008 and IEC60502 recommended by international Electrotechnical Commission. The normal operating temperature of the conductor of polyvinyl and XLPE insulated cable is 70â?? and 90â?? ,Xlpe cable not only has excellent electrical performance, high working temperature, large transmission capacity, but also has the advantages of simple structure, small outer diameter, light weight, easy installation and use, and unrestricted laying drop. It is widely used in industrial and mining enterprises and urban power grid.

The characteristics of the new type of ocean power cable are as follows: the cable core is composed of insulated cable core and waterproof filling rope twisted together; An inner sheath layer, an armoring layer and an outer sheath layer made of polyolefin are successively arranged on the outer core of the cable from inside to outside. With high softness and according to the characteristics of sea salt fog, strong light, wind and rain, easy to mildew. The above environmental factors are fully considered in the selection of cable raw materials. The cable has the environmental requirements of anti-salt spray, anti-ultraviolet light, anti-seawater and anti-mildew under the condition of meeting its own requirements. It is suitable for military power distribution network or industrial facilities in Marine environment. Its remarkable technical characteristics are high mechanical strength, oil resistance, mud resistance, uv resistance, bunching flame retardant/fire prevention, high temperature resistance, low temperature resistance, etc. The cable adopts the structure design of power core, communication and data transmission cable integrated.

Flexible fireproof cables are composed of copper stranded wires, mineral compound insulation, and mineral compound sheaths. This kind of cable has non-combustible, smoke-free, non-toxic and fire-resistant characteristics. The structure of the flexible mineral insulated cable adopts a flexible structure and materials that are made of mineral compounds, which make up for the defects of hard structure, flammability, and toxicity. It also has some advantages that other cables cannot have, such as: fire resistance, large current carrying capacity, Impact voltage resistance, mechanical damage resistance, halogen-free, non-toxic, explosion-proof, waterproof, corrosion resistance, long life, safety, overload resistance, high temperature resistance, low cost, etc. Flexible fireproof cables have an important role in protecting lives, materials, and information security. They are used in trunk lines, fire lines, escape rescue systems, such as emergency lighting, fire monitoring, alarm systems, elevator systems, smoke exhaust systems, and control lines, etc. Flexible fireproof fireproof cables used in trunk lines, fire lines, escape and rescue systems, such as emergency lighting, fire monitoring, alarm system, elevator system, smoke exhaust system, and control lines, etc. Flexible fireproof fireproof cables used in Public buildings: high-rise buildings, underground buildings, hotels and restaurants, hospitals, schools, business centers, government affairs centers, department stores, large supermarkets, logistics warehouses, financial institutions such as banks, securities and insurance, post and telecommunications centers, power control rooms, substation rooms, museums, memorials and other historic buildings.
