E series equipments' using a chopper(call a chopper as follows) is the type chopper of the plastics outer shell of a kind of nicety with small scaled new generation, its structure is cleverly made and reasonable, adopt a liquid to press an electromagnetism type to conduct electricity to flow to take off to button up a machine, ability at surroundings the environment temperature change bigger scope or have under the environment condition of vibration and pound at use. That chopper is applicable to direct current, DC 80 Fus and communicate 230/400 Fus and following electricity system in Be a circuit over carry to break down a protection with short circuit, may also Be not and multifariously connect with cent cut the power road it use. Can broadly used for calculator and its peripherals, industry automation equipments, correspond by letter line circuit and power supply device, without a break the power supply equipments, orbit transportation motorcycle, ship use an electricity equipments and move a power supply equipments in.

That series' chopper can take an assistance to touch a head and divide the Li take off to button up machine device to pack an enclosure inside etc. And provide signal designation with long-distance leave to take off to button up a control, strengthenned electricity system function, extended usage scope.
