Scope:
ly series of toroidal transformers for 50-60HZ, rated working voltage is not higher than 500V circuit as electronic instruments, household appliances (such as: drinking fountains) and machine tool equipment in the electrical power supply.
ly series of toroidal transformer with small size, light weight, simple structure, and full use of the magnetic core material, the shorter the length of the magnetic circuit, winding evenly distributed throughout the core surface. And close to the core, so that a better electromagnetic coupling, magnetic flux leakage is smaller, so that long winding turns decreases, lower internal resistance, it is the first choice of audio equipment.
Normal conditions of use:
Transformer under the following conditions can be reliably work.
A, altitude not more than 1KM
B, ambient temperature: -25 ~ 55 degrees Celsius.
C, air relative humidity less than 90%
D, in ambient air, does not contain corrosive metal and undermine the insulation system of harmful gases or dust, in use, not to make the transformer by water, rain, snow erosion.
E, the supply voltage wave
