UPS and industrial power magnetic components
Cold Cathode Fluorescent Lighting (CCFL) Inverter Transformer
Cold Cathode Fluorescent Lamps (CCFLs) are used to illuminate Liquid Crystal Displays (LCDs). The LCD display is used in laptop computers, gas pumps, automobiles, test equipment, PDAs and medical instruments.
CCFLs are small, efficient and inexpensive. The lamp must be driven by a specialized power supply. High sinusoidal AC voltage is needed to start the lamps, but once started, the voltage drops to a lower level. CCFL circuits are usually powered from a low voltage DC source of 5-12V. The DC to AC power supply needs a transformer to change low DC input voltage to high sinusoidal AC voltage.
Magnetic group devices for rail transit and power quality
Due to the special use of track, aviation and other power control power supply field, so that its application of magnetic devices, must have higher reliability and complex environmental adaptability, based on this special requirements, in the main transformer and other important devices, are installed metal shell and device integral filling sealing process, the key devices play a fixed, dust, radiation, and better heat dissipation effect.
Network communication and cloud services magnetic components

With the communication, the cloud concept power supply requirements to high efficiency, small size, low loss, modular development, driving traditional magnetic device products, in such applications to improve and optimize to adapt to the development of new communications, cloud concept power supplies.

Intelligent Internet of Things and traditional home electromagnetic group devices
