Alloy designations
The aluminium industry has created a system using a fourdigit numerical designation to identify wrought aluminium alloys The first digit indicates the major alloying element The second digit indicates whether there was a modification in the basic alloy The third and fourth digit indicates the specific alloy
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".

Aluminium 6063, also known as architectural aluminum, is one of the most popular aluminum alloys for extrusion. This alloy is widely used for its excellent mechanical properties, corrosion resistance, and suitability for forming into complex shapes. Its ease of welding, heat treatability, and smooth finish make it a preferred choice in a variety of applications.
Composition and Alloying Elements
Aluminium 6063 is primarily composed of aluminum (Al) with two main alloying elements: magnesium (Mg) and silicon (Si). These form the intermetallic compound Mgâ??Si, which is crucial for its mechanical strength. Other trace elements may include iron (Fe), manganese (Mn), and chromium (Cr), which contribute to its extrudability and corrosion resistance.
Mechanical Properties
Aluminium 6063 is known for its moderate strength. It has a yield strength of around 290 MPa and a tensile strength ranging from 310 to 340 MPa. Though it is not as strong as other aluminum alloys like 6061, its mechanical properties make it ideal for structural applications where strength is secondary to appearance or corrosion resistance.
Corrosion Resistance
One of the defining characteristics of aluminium 6063 is its high resistance to corrosion. This is due to the presence of magnesium and silicon, which protect the material from oxidation and environmental damage. This makes it ideal for outdoor applications like window frames, door frames, and architectural finishes.
Thermal and Electrical Conductivity
Aluminium 6063, like other aluminum alloys, is an excellent conductor of heat and electricity. Its heat treatable properties allow it to be strengthened through processes like tempering, making it suitable for heat exchangers, radiators, and electronic applications.
Applications of Aluminium 6063
Extrusion: Aluminium 6063 is widely used in extruded profiles such as rods, bars, and tubes. It is the preferred alloy for producing complex shapes due to its excellent extrudability.
Construction: Known for its appearance and durability, 6063 is used extensively in architectural applications like window frames, curtain walls, and other building components.
Automotive and Aerospace: Its lightweight properties and corrosion resistance make it a viable option for non-critical structural components in vehicles and aircraft.
Main functions:
1. Decrease starting current.
Utilizing soft start as the most general application starting mode, the motor is given an initial voltage setting, from the initial voltage level; the output voltage to the motor is steplessly increased to the rated full voltage in the pre-setting ramp time. The starting current of the motor is limited in 2 times of the rated working current, while the conventional full voltage starting current is 5 or 6 times of the rated working current. The limited soft starting current can decrease the insulation damage to the motor & the cable and avoid the problem of mechanical and electric pressure as well as lengthen mechanical life of the ESP-unit and reduce maintenance.
2. Eliminate operating over-voltage.
Utilizing soft stop as the most general application stop mode, the output voltage to the motor is steplessly decreased from the full voltage to the point where the load torque is greater than the developed motor torque, this can eliminate the 3 or 4 times operating over-voltage occurred with conventional coast-to-rest stop or unexpected power-off. The destruction of the 3 or 4 times operating over-voltage is always a deathblow especially to the worn-out and low-insulating motor.
3. Surge voltage absorption equipment
The built-in resistance-capacitance surge voltage absorption equipment can effectively reduce the destruction of the opposing electromotive force occurred with coast-to-rest stop or unexpected power-off, so as to protect the motor.
4. By-pass contactor
If the Controller senses that the soft starter itself has a malfunction, the output voltage can be switched to full voltage (Power-Frequency) to ensure the continuous running by the built-in bypass contactor.
5. Auto-startup under load time delay
When mechanical unit soft stop under load, if user turn on the auto-startup when under load, it will soft start automatically by the time delay setting.
6. Consummate protection
It can protect the mechanical unit not only overload, under load, short circuit, phase loss, three phase unbalance, but also over voltage and under voltage protection, when this mode is turned on, when the working voltage is higher or lower than the setup value it can stop to protect the mechanical unit.
7. Backlit LCD display and programming keypad.
The human interface modules, a display panel and a Switchboard, can be used to program and display the following technical parameters:
* Three-phase current *Three-phase voltage
* Active Power *Reactive Power
* Apparent Power *Power factor
*175 pieces of diagnostic and running data
*Power Consumption.
8. Default Phase and Phase discrimination Protection
When the phase order is default or connect wrong, the unit would not start and clue on the LCD screen.
9. Grounding automatic-alarming function.
10. Display the online detection of unit insulated resistance. (*as usersf+ requirement)
11. Communication and remote control.
The Soft Controller can be configured to communicate via radio (and GSM or GPRS) or wire-line to computer in remote control center. The controller supports ModBus protocol. (*as usersf+ requirement)
All in one sentence, The QYRK serial Soft-Start Switchboard has very important meaning for lengthen the mechanical unit life, reduce maintenance and the ESP colligate cost. Normal ESP switchboard doesn't have these features.
