This module is small in volume and integrates several functional blocks, including a feedback loop for current regulation, a power factor correction (PFC) stage, a main control stage, and a protection circuit.

Application Field

UBA2024P/N1,112 is widely applied in lighting and ballast controllers, such as in CFL, induction lamps and program start lamps, etc. It is characterized by having extremely low standby power consumption, low current start time, online dimming, and high power efficiency. It is a high-performance, low-cost solution which can meet the customer requirements for a variety of dimming applications.

Working Principle

The UBA2024P/N1,112 light ballast controller module will operate with a minimum standby power consumption. It features low current start time, which is especially ideal for CFLs, energy saving lamps and other dimmable lighting applications. The power factor correction (PFC) stage includes the primary control device and the soft switching circuit, which provides high power factor, low output harmonic distortion, and high reliability independently. The PFC stage has a wide input voltage range and a high power factor, and it is commonly composed of four elements. It adopts a design of two-level structure, and includes a maximum power point tracking (MPPT) controller, a driver, and a dimmer circuit.

The main control board of the UBA2024P/N1,112 module achieves protection and the current control of the electronic ballast, by adopting the non-time control method, a precision current control loop and a feedback phase shifting circuit. Under normal operating conditions, the power stage is operated with a stable rectangular wave current, to ensure a good dimming performance and high power factor. The module also supports online dimming, which allows users to be able to achieve different dimming modes, such as on/off dimming, long life dimming and energy saving dimming, etc.

The UBA2024P/N1,112 module has an excellent protection feature and includes a low voltage protection circuit, an over temperature protection circuit, an over current protection circuit, and a short-circuit protection circuit, etc. The system also incorporates a multi-stage power normalization and control circuit, to stabilize the output voltage and current of the electronic ballast, to prevent overshooting and undershooting of output voltage and current, and to ensure the smooth operation of the system.

Conclusion

In conclusion, UBA2024P/N1,112 is an excellent and cost-effective lighting and ballast controller module, with a wide range of applications for various types of dimming applications. It features low current start time and high power efficiency, meeting customer requirements for reliable and efficient dimming control. The built-in features, such as a feedback loop for current regulation, a power factor correction (PFC) stage, a main control stage, and a protection circuit, ensure a high degree of protection and compatibility with energy-saving lamps and other lighting applications.
