Medical Toroidal Transformers

A.  Overview
A transformer commonly used to provide suitable power to various medical and peripheral equipment.

B.  Features
The toroidal transformer used in medical device has the characteristics of low leakage flux, low interference to the periphery and low working temperature rise.

C.  Design Consideration
1.  Strengthen the insulation leakage current is low
2.  Low magnetic leakage
3.  Low interference
4.  Thermal protection
5.  Low temperature rise of the product
6.  Low vibration and noise
7.  International Medical Safety Standards
8.  Power 10VA to 10KVA

D.  Temperature resistance and product temperature rise
Typically we design that over an ambient of 25°C, the product temperature rise according to Class A(105°C), temperature rise below 60°C or suit.

E.  Compliance Standard
EN60601-1 3rd

F.  Design required parameters
1.  Input voltage (V)
2.  Working frequency (Hz)
3.  Output voltage (V)
4.  Output current (A) or output power (W)
5.  Transformer installation space
6.  Transformer installation and connection method
7.  Requirements of temperature resistance level, efficiency, power consumption
