SM2420G

The SM2420G is a professional electronic control circuit for all kinds of lamps, especially incandescent lamps, neon lamps and other lamps. Its structural design is reasonable, the control circuit is reliable, the failure rate is low, and it has higher performance. Therefore, it is widely used in intelligent lighting engineering, stage sound and lighting engineering, stage art engineering, film and television lighting engineering, television studio lighting, power plant lighting engineering, new energy lighting engineering and other projects.

Design & Structure

The SM2420G is designed to work in a wide variety of temperature and humid weather conditions. It comes with a cooling fan, so the SM2420G can operate continuously for long hours without any problems. The SM2420G is designed for multiple dimming and is a constant current power supply. It has a strong overload protection, short circuit protection, overvoltage protection and temperature protection function, which can reliably protect the safety and stability of the power device.

Applications

The SM2420G is ideal for controlling incandescent lamps, neon lamps, and other lamps. It can be used to control the brightness, flashing speed, loop connection circuit and other effects of incandescent lamps. It can also be used to provide constant current for miniaturized neon lamps, so as to achieve the dynamic effect of long strip neon lamps and so on. It can also be used to control the single color, dual color, RGB and other lamps, to make color effect changes, so SM2420G application field is quite broad.

Working Principle

The working principle of SM2420G is simple. It uses chip control output and PWM components. Signal control is achieved through chip. When different signals are input to the control pin of the chip, the current output of the power supply can be adjusted, and the output current is proportional to the pulse width of the adjustable signal, so as to realize the dimming effect on the connectedload. At the same time, the jumper can also be adjusted to make the power output constant current, ensuring the safety of neon lamps and other lamps.
