Basic Principles and Functions of Medical Isolated Power Panels

With the continuous advancement of medical technology, the complexity and precision of medical equipment are also constantly improving. Among these devices, the stability and safety of the power supply are crucial. As a special type of power supply equipment, the medical isolated power panel plays a pivotal role in the medical field. This article will delve into the basic principles and functions of the medical isolated power panel.

The Basic Principles of Medical Isolated Power Panels

The core principle of a medical isolated power panels is electrical isolation. It primarily uses an isolation transformer to isolate medical equipment from the grid power supply, thereby eliminating ground current and ensuring power stability and safety. Specifically, the medical isolated power panel transforms the TN power supply mode into IT power supply mode, where the neutral line (N line) is not grounded but forms a loop with the equipment's load through the isolation transformer. In this way, even if the equipment leaks electricity, it won't form a circuit, thus avoiding electric shock incidents.

In the stabilization process, the medical isolated power panel maintains output voltage stability by adjusting the frequency of the output pulses (i.e., adjusting the pulse hiatus time). When the output voltage drops, the control system automatically increases the pulse frequency to allow the pulse transformer to store more energy and release it when needed to maintain output voltage stability; conversely, when the output voltage rises, the control system reduces the pulse frequency, thereby reducing energy storage and release, thus maintaining output voltage stability.

The Main Functions of Medical Isolated Power Panels

Ensuring Patient Safety

The medical isolated power panel isolates patients from the grid power source through electrical isolation, eliminating ground leakage currents and electrical hazards. This provides a safe and reliable medical environment, crucial especially for patients requiring treatment with implantable medical devices.

Stable Operation of Medical Equipment

The medical isolated power panel delivers stable and reliable power supply, ensuring the normal operation of medical equipment. Stable power supply is critical for maintaining the accuracy and reliability of medical devices. Through precise voltage regulation and filtering techniques, the board ensures stable and clean output voltage, enhancing the performance of medical equipment.

Reducing Electromagnetic Interference and Noise

Medical environments are often filled with electromagnetic and electrical devices that generate interference and noise during operation. The medical isolated power panel employs special filtering and shielding technologies to effectively reduce these interferences and noise, thereby improving the accuracy and stability of medical equipment operation.

Enhancing Long-Term System Stability

In addition to the above functions, the medical isolated power panel is equipped with auxiliary devices like insulation monitoring equipment to continuously monitor the insulation levels of the power system. It triggers alerts and cuts off power supply when insulation levels drop below a certain threshold, preventing safety accidents caused by insulation faults. This real-time monitoring and alert mechanism contribute to the long-term stability and reliability of the power system.

Application Scenarios of Medical Isolated Power Panels

Medical isolated power panels are widely used in various medical facilities and equipment. They are particularly indispensable in critical areas such as operating rooms, intensive care units, and cardiac care units, where medical equipment is directly linked to patient safety and requires stable and reliable power supply.

As a specialized power equipment, the medical isolated power panel plays a crucial role in the medical field. It isolates patients from the grid power source, eliminates ground leakage currents and electrical hazards, provides stable and reliable power supply through precise voltage regulation and filtering, and enhances system stability with insulation monitoring capabilities. With continuous advancements in medical technology, the medical isolated power panel is expected to be more widely applied and developed in the future.
