electro-magnet drum brake

electro-Magnet drum brake operation conditions:

altitude above sea leval of the safety brake using place should not surpass 1000m.

electro-magnet drum brake temperature of the surround media is -25°C-+40°C

brake air relative humidity should not be larger than 90°C.

electro-magnet drum brake operating frequency<720once/h

the media that does not have the explosion hazard,does not have the gas that sufficiently dips and destructs the insulation and the electric conduction dust.

rated voltage of parallel connection coil is 110V,the continuing percent of elctrifying is 25°C,if choos other voltage rank,the continuting percent of electrifying whne maintain the suction,it's need to series connection the additional resistance(the additionaly resistance is supplied by the user oneself)

If the user doesn't have or needn't to have the addtional resistance(please exlain at the time of ordering electro-magnet drum brake)
