Automatically controlled board fan test circuit of air conditioner

In order to overcome not enough that current technique exists, the utility model provides an automatically controlled board fan test circuit of air conditioner, the utility model discloses a test panel, rotational speed test interface, fan plug wire interface, power are surveyed to step motor, LED lamp, 5P scanning head, fan, rotational speed, step motor and resistance polyphone, then parallelly connected LED lamp and 5P scanning head, the electrical property links to each other between fan, rotational speed survey test panel, the power, the electrical property links to each other between rotational speed test interface, rotational speed survey test panel, the power, the electrical property links to each other between fan and the fan plug wire interface, this automatically controlled board fan test circuit of air conditioner can effectively monitor each gear wind speed speed, can be more effectively directly perceived, differentiate that a step machine waves and turn to and the test of fan rotational speed. 为
