  Automotive Electronics & New Energy

  The control system of a car is based on electronic devices, and as the most important part of the intelligent car ecosystem, the performance of automotive electronic devices directly determines the safety and reliability of the entire vehicle. FBelec Power has over a decade of technological accumulation, providing intelligent, convenient, and leading automotive electronic testing solutions for automotive electronics, automotive generators, high-voltage battery systems, high current relays, inverters, electrical air conditioning compressors, power transmission hydraulic pumps, DC motors/DC-DC high and low voltage converters, DC brushless motors, automotive safety wires, car lights, wireless power supply, magnetic drive, and other fields.

  The FBelec automotive electronic intelligent ecological testing system has China's first HY-BP16750 series high-speed power supply with a maximum frequency of 500kHz for automotive electronic testing. The HY-BP series high-speed power supply for automotive electronic testing is a bipolar DC stabilized power supply that continuously passes through zero points without polarity switching at the output end, and can change both positive and negative poles in both directions. Through the four quadrant action, it is possible to provide both source and sink power, driving both inductive and capacitive loads. At the same time, it also has a built-in function signal generator, which can freely generate any waveform and set timing control. It also achieves low ripple, low noise, and high-speed response (CV mode: 500kHz), with a voltage response time of only ≤ 10 μ S. Applicable standards: Power supply voltage variation tests (pulse 2b, pulse 4, etc.) required by ISO 16750-2 and ISO 7637-2, GB28046.2, and can meet the high-speed response speed requirements of various automotive manufacturer standards: LV 124, LV148, SMTC3 800 001, VW 80000, GS 95024-2, and increasingly complex waveform variation tests.

  
  

  The correct steps for selecting the model of AC/DC Power Supply

  1. The first step is to determine the input source type
  There are two types of power module inputs: AC or DC. Generally, AC/DC power module is selected for AC input, and DC/DC power module is selected for DC input. The high-energy cubic AC-DC power module can also operate normally under DC input voltage conditions.
  
  2. The second step is to select based on the input voltage range
  After determining the input source, the input voltage can refer to the manufacturer's selection framework. The conventional AC inputs are 110V, 220V, and 380V. Nowadays, most AC/DC power modules meet the input range of 85-265VAC or 100-370VDC. 380V also meets the input range of 220V. However, the performance may be much worse when used at 220V, and the conventional DC input ranges from 5V to 72V.
  
  3. Step 3: Select the packaging type of the product
  The packaging forms of the product include single inline SIP packaging, small horizontal bare board packaging, dual inline ultra small DIP packaging, and rail packaging. Bare board is composed of PCB and various components, completely exposed, not very safe, but with low cost. It is generally recommended to use DIP packaging. Although it is slightly more expensive, it is a sealed packaging with safe isolation, good heat dissipation performance, shock resistance, waterproofing, and stable performance. It needs to be selected according to the actual situation.
  
  4. Step 4: Select the power of the product based on the size of the load
  When selecting the power of the power module, it is generally recommended to leave a margin, and the power used should be between 20% and 80% of the actual power. Excessive margin may cause howling during low-frequency operation. If the margin is too small, it may cause a reduction in module lifespan, reliability, and even the inability to start.
  
  5. Step 5: Choose the appropriate output voltage based on the type of load
  The output voltage of the product is generally 3.3V, 5V, 6V, 9V, 12V, 15V, 20V, 24V, 28V, 36V, 48V, ± 12V, ± 15V, etc. Some unconventional voltage requirements can be achieved through series combination. If the routine requirements are not met, you can also request customization of the output voltage you want from the manufacturer. It is not complicated to change it on the original basis, and it can be basically achieved.
  
  6. Step 6: Select the isolation properties of the power module
  There are two types of power modules: isolated and non isolated, and non isolated can pose a risk of electric shock. Isolation refers to the complete isolation of the input and output of the power module into two independent (non grounded) power sources. In industrial bus systems, complete isolation is carried out when facing harsh environments (lightning strikes, arc interference), which plays a role in eliminating grounding loops. In hybrid circuits, achieve noise isolation between sensitive analog circuits and digital circuits, and achieve voltage conversion in multi voltage power supply systems. The conventional AC/DC power module is 3000VAC, while the DC/DC power module has 1000VDC~3000VDC.
  
  7. Step 7: Select the working temperature range
  Working temperature is an important factor affecting the lifespan of power modules, including commercial, industrial, and military grades, with significant price differences between different grades. Considering cost factors, it is also possible to choose a higher power one and reduce the rating for use. You can refer to the reduction curve in the specifications.

• Frequently Asked Questions (FAQ)

  
  

  
  

  Can a DC power supply be used for both prototyping and production?

  Yes, many DC power supplies are versatile enough to serve both prototyping and production needs. Programmable units are particularly beneficial in production environments where different test scenarios may be required.

  
  

  How does a DC power supply work?

  A DC power supply works by providing a regulated direct current to power a component, module, or device. Most DC power supplies have two modes of operation. In Constant Voltage (CV) mode, the power supply controls the output voltage based on the user settings. In Constant Current (CC) mode, the power supply regulates the current.

   

  
  

  Usage of DC power supply

  1. Connect the power supply first, and then connect the voltage regulator to the power supply.

  2. Turn on the power supply, turn on the main switch when there is no load, and then turn on the DC output switch to ensure the normal operation of the power supply. If the operation is normal, the power indicator will display the current output current and working voltage.

  3. Set the output voltage, adjust the voltage setting button, set the voltage to the desired voltage, and complete the voltage setting. This way, for a current limiting power supply, there are two adjustment systems to adjust the current and voltage separately.

  4. Set the current, press the limit button on the power panel, and the ammeter will display the current value. Adjust the current button to meet the requirements.

  5. Set overvoltage protection to avoid outputting excessive voltage in the event of incorrect operation.

  6. The setting of communication interface and remote control operation should be turned off relative to local control, such as setting communication interface according to requirements.

  
  

  What is a DC power supply?

  Also known as a DC power supply system or DC power supply, it is an electronic device used to provide stable DC voltage and current to circuits. Its core components include a positive electrode and a negative electrode, and there is a certain potential difference between these two electrodes. When the two electrodes of a DC power supply are connected to the circuit, a constant potential difference can be maintained, thereby generating current at both ends of the circuit.
