High-voltage power supplies are electronic power devices widely used in industry, scientific research, and other fields. They typically have high output voltage and low output current. So, do you know what protection functions high-voltage power supplies have? This article will introduce the common protection functions of high-voltage power supplies. We hope this will be helpful.
Overvoltage Protection
Overvoltage protection means that when the input voltage of the high-voltage power supply exceeds the set protection voltage value, the power system will automatically shut down the output to prevent the voltage from continuing to rise and causing damage to the power system or equipment. Overvoltage protection is usually implemented using a voltage comparator or voltage sensor. When the input voltage exceeds the set protection voltage value, the protection circuit will automatically trigger, causing the power system to shut down the output.
Overcurrent Protection
Overcurrent protection means that when the output current of the high-voltage power supply exceeds the set protection current value, the power system will automatically shut down the output to prevent the current from continuing to increase and causing damage to the power system or equipment. Overcurrent protection is usually implemented using a current sensor or current detection chip. When the output current exceeds the set protection current value, the protection circuit will automatically trigger, causing the power system to shut down the output.
Over-temperature protection
Over-temperature protection automatically shuts off the power supply output when the internal temperature exceeds a set protection temperature to prevent further temperature increases and damage to the power supply system or equipment. This is typically implemented using a temperature sensor. When the internal temperature exceeds the set protection temperature, the protection circuit automatically triggers, shutting down the power supply output.
Short-circuit protection
Short-circuit protection automatically shuts off the power supply output when a short circuit occurs at the output terminal to prevent damage to the power supply system or equipment. This is typically implemented using a current or voltage detection chip. When a short circuit occurs at the output terminal, the protection circuit automatically triggers, shutting down the power supply output.
Overload protection
Overload protection automatically shuts off the power supply output when the output current exceeds a set protection current value to prevent excessive current from damaging the power supply system or equipment. This is typically implemented using a current or voltage detection chip. When the output current exceeds the set protection current value, the protection circuit automatically triggers, shutting down the power supply output.
Grounding Protection
Grounding protection refers to the automatic shutdown of the power supply output when an abnormality occurs at the grounding terminal of the high-voltage power supply, preventing damage to the power system or equipment caused by the abnormality. Grounding protection is typically implemented using current or voltage detection chips. When an abnormality occurs at the grounding terminal, the protection circuit automatically triggers, shutting down the power supply output.
The above are the relevant protection functions of high-voltage power supplies. When purchasing a high-voltage power supply, the appropriate protection function should be selected based on the specific application scenario and requirements to ensure smooth operation of the power supply.
