The portable DC high voltage generator AN983B is an important tool specifically used for power testing. China has established detailed technical standards for it, aiming to ensure that such equipment can operate stably and safely under any circumstances and meet the needs of various applications.



1. Working Environment Requirements:

   - This instrument can operate normally in ambient temperatures ranging from 0°C to 40°C, just like humans, where extreme cold or heat may affect its performance. Humidity also matters; for instance, at 25°C, the relative humidity should not exceed 85%, as if the machine also needs to avoid "sweating". Additionally, it can work smoothly at altitudes not exceeding 1000 meters; if it needs to be moved to higher places, a specially customized version is required. The power supply is similar to household outlets, typically 220V single-phase AC, with voltage fluctuation not exceeding ±10%, or 380V three-phase AC, also allowing ±10% fluctuation. The power frequency, the "heartbeat" of the power source, is required to be around 50Hz, with an error not exceeding ±1%.



2. Performance Indicator Requirements:

   - The DC high voltage it generates must be very stable, like a calm river, without significant fluctuations. To achieve this effect, engineers often adopt medium and high-frequency rectification and filtering technologies to make the voltage output smoother. At the same time, this equipment must be an excellent insulator, able to withstand high voltage tests, ensuring user safety.



3. Automatic Protection System:

   - Like a smart safety guard, the equipment is equipped with multiple protective measures such as overvoltage, overcurrent, and zero-position protection. Once an abnormal situation is detected, it can immediately cut off the high-voltage output to prevent equipment damage or safety accidents. Moreover, these protection functions are quite robust and not easily misled by external interference. As for the critical safety setpoints, designers have thoughtfully designed anti-misoperation features, such as hiding important knobs in small holes on the panel, so that users are less likely to accidentally change safety settings during experiments.



4. Structure and Portability:

   - The design pursues lightness and portability, like a sturdy and durable small piece of equipment that can easily handle various complex on-site testing environments. The overall structure is rigorous, complying with safety operation regulations while facilitating daily maintenance and repair.



5. Other Technical Details:

   - For more details of the equipment, such as the variation range of output voltage, the impact of load on voltage, temperature rise during operation, operating noise level, and working efficiency, there are strict regulations. Additionally, the equipment needs to have a certain measurement accuracy, with clear and visible data on the display screen, and the operation method should be simple and easy to understand.



These technical conditions are formulated according to relevant industry standards in China, such as referencing the ZBF24003-90 specification. However, with the advancement of technology and the passage of time, current standards may have been updated and upgraded. Therefore, in specific use, we must consult the latest national standards and industry regulations.
