ISOLATED POWER SYSTEMS

Acrel Isolated power systems are mainly used in the medical and industrial
sectors. The medical IT system is mainly designed for the large threat to the
patient's life caused by the leakage current. The industrial IT system is
mainly used to monitor the insulation condition of the system to the ground in
real time because the leakage current poses a threat to the safety of some
industrial production.

Isolated Power Systems For Sale
Isolated power distribution system is suitable for important places such as
hospital operating rooms, ICU (CCU) intensive care units, and industrial fields
such as: electrolytic aluminum, mines, glass factories, electric furnaces and
test equipment, metallurgical plants, chemical plants, explosion-hazardous
places, computer centers and emergency In AC and DC ungrounded systems such as
power supplies.

Isolated Power System Explained
In the medical IT system, the AITR series medical isolation transformer is the
core of the system. It is used with the AIM series insulation monitor to
monitor the insulation status of the IT system to the ground. When an
insulation fault occurs, the AID series alarm and display instrument will
remotely display and Sound and light alarm, at the same time ASG test signal
generator and AIL insulation fault locator will locate the location of the
fault, so as to cut off the fault circuit in time and accurately.

Isolated vs. Non-Isolated Power Supply

Different risk of electric shock

A. Non-isolated power supply: There is a direct connection between the load end
and the input end, which will introduce the high voltage of the AC power supply
to the load end, thereby causing the danger of electric shock.

B. Isolated power supply: The load terminal and the input terminal are
indirectly connected, so there is no danger of electric shock when touching the
load.

01

The driving efficiency is different

A. Non-isolated power supply: The driving efficiency is high, and the voltage
range is 110-300V.

B. Isolated power supply: The drive efficiency is low, and the voltage range is
60V-300V.

02

The cost is different

A. Non-isolated power supply: The circuit structure used is a DC/DC boost or
buck circuit scheme, the circuit is simpler and the cost is lower.

B. Isolated power supply: The circuit structure used is an AC/DC flyback
circuit scheme, which is complicated and expensive.

03
How Does An Isolated Power Supply Work?
Medical isolation power system (ie medical IT system), also known as power
distribution system with ungrounded neutral point. The power supply side of the
system has no working grounding or is grounded through high impedance, and
grounding protection is performed on the load side. Therefore, when the first
leakage fault occurs, the leakage current is small and will not generate a
large contact voltage to threaten personal safety. Therefore, It is not
necessary to cut off the power supply, so that the medical equipment can
continue to work, and at the same time, the alarm device is used to remind the
staff to check and eliminate the fault in time.
