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".

Temperature Protection PTC Thermistor Description PTC (positive temperature coefficient )thermistor switches at one particular temperature. Making use of the characteristics that the resistance of PTC thermistor increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit installed PTC thermistor will turn on or cut off loop through resistance changing, achieving thermal protection purpose. PTC thermistor protect such equipment and components as motors, transformers, power transistors and thyristors against over-temperature. A PTC thermistor is less expensive than a thermostat, and its switch temperature can be more accurately specified. It is also smaller and easier to design-in to electronic circuitry. Therefore PTC thermistor can be ideal devices for temperature detection, monitoring, indicating, limiting and over (excessive) temperature protection. Typical Application of PTC Thermistor for Temperature Protection and temperature limiting sensors Limit temperature measurement of Industrial electronics application. Power supplies, switch power supply. Home appliances, such as dish washers, washing machines, ironing machines, electric cookers, etc. Electronic data processing and communications engineering (DC/DC converters). Motor windings overheating Protection. Automotive electronics. Semiconductor heatsinks, enclosure panels, temperature-limited transistors. Lighting applications. Features of PTC Thermistor for Temperature Protection and temperature limiting sensors 2 Outlook construction: A-radial leaded epoxy resin coated form, B-metal tag lug form. PTC Thermistor Protection temperature: 60-130C Quick response. Long stability. Small dimension, convenient for installation. Do not need to be reset after protection.

Application :- This is a premium product of electrical wires from \'JPCL\'. These cables are ideal for wiring in residential and commercial complexes, high-rise buildings, hotels, hospitals, schools, colleges, etc. (where the density of people is high). During a fire, these cables not only emit less smoke and toxic hydrochloric acid gas but also retard the spread of fire enabling those trapped inside to escape safely. Features :- Manufactured from bright annealed 99.97% pure bare copper conductors, these cables have low conductor resistance resulting in power saving. These wires are insulated with a special grade PVC compound formulated and manufactured in-house only. The insulation is far superior in terms of critical oxygen and temperature index as well as in light transmission and acid gas generation. The skin coloration offers high insulation resistance and long life.
