Acrel AITR Medical isolation transformer
Acrel AITR Medical isolation transformer
General
Acrel AITR series isolation transformer is specially used in medical IT system. The transformer core is made of silicon steel sheet, the loss is small. Double insulation treatment is adopted between windings, and a static screen is designed to reduce the electromagnetic interference between the two windings. PT100 temperature sensor is installed in the winding, which can be used to monitor the winding temperature. The transformer is treated by vacuum impregnation, which increases the mechanical strength and has anti-corrosion effect. In addition, the product also uses low temperature rise and low noise design, so that it has good temperature rise performance and low noise.

Advantages of Hospital Isolated Power System
Medical isolated power panels provide safe, reliable and continuous power distribution for the important equipment at these locations:
• Used for the transformation of TN system into IT system (ungrounded system)
• Functions of real-time monitoring and fault alarming of the ground insulation resistance, transformer load current and transformer winding temperature of the monitored IT system
• When the monitored IT system has an insulation fault, the hospital isolation panel can initiate and generate the fault location signal to the system, and realize fault locating function with the help of the fault locator
• Acrel hospital isolated power systems can remotely monitor the real-time operating conditions of up to 16 pieces of systems, and the main interface intuitively displays whether the access system communication is intact
Acrel Medica/Hospital Isolated Power Systems FAQs
It is an isolated power supply system that conducts insulation monitoring and fault determination of the power distribution system, to further provide safe, reliable and continuous power distribution.
Real-time monitoring of the insulation, load and isolation transformer temperature of the IT system, with functions such as system insulation fault circuit location and centralized monitoring of multiple systems.
The medical isolated power supply system consists of a medical isolation transformer, medical intelligent insulation monitoring instrument, current transformer, insulation fault locator, test signal generator, power module and centralized alarm and display instrument.
You can find medical isolation panels in operating rooms, ICU/CCU intensive care units, premature infant care units, delivery rooms, hemodialysis centres, emergency rooms and other important medical places.
