(PROJECTS)Application of ACREL Medical IT Insulati

 
Background 
Electric shock and system fault caused by power distribution system are mostly caused by the grounding fault of equipment line. Grounding fault will directly bring the harm of power supply interruption; when the earth fault leakage is serious, it will even burn electrical equipment or lines, causing irreparable loss.
In Medical places, especially those life-threatening class 2 medical places, patients in operation or anesthesia state, without self-behavior ability, small leakage current can lead to electric shock death of patients. Therefore, the electrical design of this special place should be carried out strictly in accordance with the relevant national standards and specifications.

IT power distribution system (also known as isolated power supply system or ungrounded system) has very small leakage current to ground due to its neutral point ungrounded. When the first insulation fault occurs, the power supply of the equipment will not be affected. So the system can continue to operate. The insulation monitoring device installed in the system can detect the fault in time and send out the corresponding fault warning, prompting the relevant personnel to remove the fault at the appropriate time. For the operation room, intensive care unit and other medical places with high requirements for power supply continuity and safety, local IT system power supply can ensure the security and reliability of power supply for important loads.
 
Project Information 
Santa Casa de Misericordia,Hospital Eduardo de Menezes Brazilian medical institutions, after comparison, selected Acrel's medical IT products and hundreds of sets have been used.

Project Summary 
The reliability and safety of electrical equipment in class II medical places directly determine the life safety of patients, which also makes electrical safety issues more important than other places. Compared with TN system, IT system has obvious advantages in security and power supply continuity, which is suitable for important load power supply in class II medical places.
At present, ACREL medical IT products have been used in a number of medical institutions in Brazil, and the customer says the products are pretty good. We hope that our products can be applied to more occasions and contribute to improve the overall security of international medical treatment.
