Micro Cooling Fan input parameters selected

User input is closely related to "Micro Cooling Fan" is the coil voltage (or current), while the pull-in voltage (or current) is a relay factory control relay sensitivity and its judgment, assessment parameters. The user is concerned, it's just a job under extreme parameter values. Control of the safety factor is the operating voltage pull-in voltage, if the relay in the pull-in value, are unreliable, unsafe, "dota2雷竞技预测 " ambient temperature or in vibration, under impact conditions, will allow the relay does not work reliable. Machine design, the no-load voltage can not work as a relay voltage basis, but rather as a load coil access to calculate the actual voltage, especially when the source resistance especially big. When the "dota2雷竞技预测 " with transistors as switching elements to control the coil off, the transistor switches must be in the state, 6VDC
