Product Description

High efficiency Toroidal Transformer

1.toroidal transformer for medical equipment
12V 220V Audio Toroidal Transformer with IEC CE
12V 220V Audio Toroidal Transformer with IEC CE

Product description:

Medical Toroidal transformer:

Medical Equipment: Beyond the Toroidal Transformer has a common transformer function,

its anti-electric strength and resistance to damp heat capacity far higher than the national standards and

industry standards.

 

Additionally oriented towards the requirements of EN 60601

Safety Temperature Limiter recommended

Security Value specified

In many cases with statically shield winding to discharge capacitively coupled

interferences, or to monitor the insulation

Especially low leakage current, which clearly under-runs the required norms(<<5 mA )

Strengthened or enhanced insulation

At minimum equipped with basic insulation

eightened creepage distance and sparking distance in air

Reduced inrush current


 

Features:

They should pay attention to the air clearance, leakage current, test voltage etc. We use the advanced machine to make sure the windings are very good performance. It should avoid the cables' broken during the production.All the wire harnesses, product enclosures etc whould be treated very carefully.

 

Application:

Medical grade isolation transformers are installed in medical devices used in hospitals, medical research facilities, and biomedical companies throughout the world. Our medical toroidal transformers are strictly monitored under safety rules, guidelines and governing laws.
