Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] As shown in Figures 1-2, the dimming overload protection controller of the present invention includes a filter circuit, an overload protection circuit and a load circuit, and also includes a dimming circuit, and the dimming circuit is connected between the filter circuit and the load circuit.

[0014] The filter circuit is composed of capacitors C01, C02, resistors R01, R02 and common mode inductor L connected through the circuit. The filter circuit can be provided by an EMC filter, that is, an EMC filter is connected to the power input end. The EMC filter is then connected to the dimming circuit through the adjustable switch SW1 and the fuse F1, and the dimming circuit is connected by capacitors C1', C1', C2', resistors R1', R2', adjustable resistor RP1, inductor L1 and thyristor Q1 and DB3 are composed of circuit connections. By adjusting the resistance value...

Abstract

This invention relates to a light-adjustable over loading protection controller including a filter circuit, an over loading protection circuit and a load circuit and a light-adjusting circuit connecting between the filter circuit and the loading circuit, said light-adjusting circuit is composed of capacitors C1, C1' and C2', resistors R1' and R2', an adjusted resistor RP1, an inductor L1 and thyristors Q1 and DB3 connected by circuit, the voltage output of Q1 is changed by adjusting the resistance value of RP1 so as to control the brightness of the load.

Description

Technical field: [0001] The invention relates to the field of light control equipment and electronic technology, in particular to an adjustable dimming overload protection controller. Background technique: [0002] The traditional overload protector can only protect and cannot adjust the light. Therefore, some products must be equipped with a dimmer. The existing dimmer cannot be connected to the power grid because the radio index does not meet the IEC standard. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of existing overload protectors and dimmers, and provide a radio interference technology that can not only protect against overload, but also realize dimming control, and fully comply with the International Electrotechnical Commission (IEC). Dimming overload protection controller with indicators CISPR15 and EN55015. [0004] The technical solution adopted by the present invention to achieve its purpose is: dimming ove...
