Toroidal - Medical isolation transformer
|
The use of an Trans-tronic isolation transformer overcomes any potential problem which
may result from the fact that electronic equipment (for example computers and lights)
are not manufactured to include medical standards. It also safeguards against power
surges within power supplies. With an Trans-tronic isolation transformer the equipment
can be isolated from the mains and thus protected against the problem of current
leakage.

Trans-tronic manufactures four medical isolation transformers from 130VA to
1kVA. These are fully approved to EN60601-1 and UL506 giving full medical
standards
|
Each transformer :
- Step up/down applications: 230V:115V or 115V:230V;
- Can be wired in series or parallel offering both 115V and 230V applications;
- Incorporates a self-resetting 125°C thermal cut out to protect transformers; and
- Copper screening between the primary and secondary resulting in low leakage current
between primary and secondary windings.
These transformers must be housed in enclosures complying with the relevant standard/s
and input & output components must be chosen to keep leakage currents within limits.
Please note that the output voltages are quoted on-load. Therefore it is important
that the correct transformer is chosen, as under high mains conditions, a lightly
loaded transformer may produce an output voltage exceeding the maximum input voltage
for the particular piece of equipment used in the medical field
