Hello everyone, I'm HUA GAO XIN KE, a power technology engineer. In industries such as industrial production, car modification, and new energy, there are often situations where "the 12V power supply cannot meet the power supply requirements of 24V equipment". At this time, the 12V to 24V 100A Step Up DC DC Converter (12V to 24V 100A boost converter) becomes the core solution. However, many users, during the selection and usage process, due to their lack of familiarity with the product's principles and application points， encounter problems such as unstable equipment operation and shortened converter lifespan. Today， I will comprehensively explain this product from four dimensions： principle, selection,installation,and case studies.

1. What is a 12V to 24V 100A Step Up DC-DC Converter? In which scenarios is it applicable?

The 12V to 24V 100A Step Up DC DC Converter is a DC-DC conversion device that raises 12V DC voltage to 24V DC voltage with a rated output current of 100A. Its core advantage is that it can provide large current power supply while ensuring the stability of the output voltage, meeting the power consumption requirements of high-power 24V devices, and has high conversion efficiency and low energy consumption, suitable for various complex working environments.

A Brief Analysis of the Working Principle of Boost Converters

This voltage booster converter employs high-frequency switching power supply technology. Its core working process is divided into three stages: Firstly, the input 12V direct current is converted into high-frequency alternating current through the switching transistor; then, the voltage is raised to the corresponding 24V high-frequency alternating voltage through the high-frequency transformer; finally, the high-frequency alternating current is converted into stable 24V direct current through the rectification and filtering circuits. The 12V to 24V 100A Step Up DC DC Converter of HUA GAO XIN KE is equipped with a high-precision control chip, which can monitor the output voltage and current in real time to ensure a stable and reliable conversion process.

2. Typical application scenarios for the 12V to 24V 100A converter (industrial equipment, vehicle modification, etc.)

Based on practical application cases, the core application scenarios of this voltage booster converter mainly include three categories: Firstly, in the field of industrial automation, such as 24V industrial controllers, servo motors and other equipment. If there is only a 12V power supply on site, it can achieve power adaptation; Secondly, in the field of car modification, the audio-visual systems, lighting equipment of some heavy trucks and campers are of 24V specification, and they need to obtain power from the 12V on-board power supply through the voltage booster converter; Thirdly, in the field of new energy, such as some 24V energy storage modules in photovoltaic energy storage systems, it can boost the output voltage of 12V photovoltaic components and charge them.

II. HUA GAO XIN KE 12V to 24V 100A Step Up DC-DC Converter Selection Core Indicators

Selection is the key to ensuring the stable operation of equipment. Many users experience frequent malfunctions due to improper selection. Based on the product development experience of HUA GAO XIN KE, it is recommended to focus on the following three core indicators:

1. Efficiency: How to determine the energy-saving performance of a boost converter?

Conversion efficiency is the core energy-saving indicator of a boost converter, directly affecting the equipment's energy consumption and operating temperature. The conversion efficiency of a high-quality 12V to 24V 100A Step Up DC-DC Converter should be no less than 92%. HUA GAO XIN KE's products adopt advanced synchronous rectification technology, with the conversion efficiency reaching up to 96%. This can effectively reduce energy consumption and minimize heat generation during operation. When selecting, you can check the efficiency parameters in the product specification sheet. Prioritize choosing products with an efficiency of ≥ 92%.

2. Stability: The impact of anti-interference capability on the operation of the equipment

In industrial and automotive scenarios, there is significant electromagnetic interference. If the boost converter lacks sufficient anti-interference capability, it will cause fluctuations in the output voltage, thereby affecting the normal operation of the downstream equipment. The 12V to 24V 100A Converter from HUA GAO XIN KE is equipped with an EMC electromagnetic compatibility module, which can effectively suppress electromagnetic interference and also has excellent voltage regulation rate (≤±0.5%). Even when the input voltage fluctuates or the load changes, it can maintain the output voltage stable. In addition, attention should be paid to the operating temperature range of the product. It is recommended to choose a product with a wide temperature range of -40℃ to 85℃ to adapt to different harsh environments.

III. Correct Installation Steps for 12V to 24V 100A Converter (with Important Notes)

The correct installation method can significantly enhance the product's lifespan and operational stability. Here are the standard installation steps and precautions recommended by HUA GAO XIN KE:

Step 1: Preparations before installation. Confirm that the input voltage is 12V DC, and the total power of the rear-end equipment does not exceed 2400W (24V × 100A), with 10% redundancy reserved; prepare matching connection cables (it is recommended to choose ≥ 16mm² copper core cables), fixing brackets, insulation tools, etc.

Step 2: Fix the product. Select an installation location that is well-ventilated, away from heat sources and flammable materials. Use a bracket to securely fix the 12V to 24V 100A Converter. Avoid vibration that may cause the wiring to loosen; a minimum of 10cm of ventilation space should be reserved around the product to ensure proper heat dissipation.

Step 3: Circuit connection. Clearly distinguish between the positive and negative poles. First, connect the input terminals (12V+ to the IN+ of the converter, 12V- to the IN- of the converter), then connect the output terminals (the OUT+ of the converter to the + terminal of the 24V device, the OUT- of the converter to the - terminal of the 24V device); the connection wires must be firmly tightened to avoid poor contact and overheating.

Step 4: Power-on Test. After the connection is completed, first check if the circuit connection is correct. Once confirmed to be correct, turn on the power. Use a multimeter to test if the output voltage is approximately 24V. Observe if there are any abnormal noises or overheating conditions during the equipment operation. If there are no abnormalities, the installation is complete.

Notes: During the installation process, the power supply must be disconnected to prevent electric shock; do not reverse the positive and negative terminals; otherwise, the converter and the downstream equipment will be damaged; when using for a long time in a humid environment, choose products with waterproof function (such as HUA GAO XIN KE IP67 waterproof model).

Case 1: A car modification factory modified a 24V audio-visual system and lighting equipment for heavy-duty trucks. The original vehicle's power supply was 12V. After selecting the HUA GAO XIN KE 12V to 24V 100A Step Up DC DC Converter, stable power supply was achieved. The audio-visual system ran smoothly, the lighting equipment maintained stable brightness, and the converter operated with low heat generation, without any electromagnetic interference affecting the vehicle's electronic equipment.
