Note: * denotes optional and customized parameters and you can select every parameter in drop-down lists to complete your order.
- The transformation ratio between the primary winding and the secondary winding is 1:1.
- The transformer winding is made of H-class enameled copper wire, with a temperature resistance of 180℃. Compact and uniform arrangement, no insulation layer on the surface, with high aesthetic feeling and heat dissipation.
- Double insulation is adopted between the windings and an electrostatic shielding layer is designed in the electrical isolation transformer.
- The medical isolation transformer adopts vacuum pressure impregnation of insulating varnish with temperature resistance of 180℃, which has extremely high heat resistance, corrosion resistance, low noise and good insulation performance.
- The hospital isolation transformer has excellent filtering effect and is used to convert TN system to IT system (ungrounded system).
- The medical grade isolation transformer has built-in PT100 temperature sensor to monitor its temperature.
Transformer Shell Features
- Steel plate shell.
- Protection class is IP20 or can be customized for you.
- There are cable entry holes.
- The housing has fixed holes for easy installation and replacement.
The medical isolation transformer is widely used in ventilators, infusion pumps, testing equipment, pulse compressors, patient monitoring equipment, high-frequency enclosure equipment, etc.
