The following is the circuit diagram of [FAN6920MR structure diagram and application circuit] The FAN6920MR integrates a critical mode PFC and a quasi-resonant current mode PWM power supply controller. For PFC, the FAN6920MR uses a controlled on-time to provide an adjusted DC output voltage for optimal THD optimization, while for PWM, the FAN6920MR offers a variety of functions. Enhance the system's power function. Mainly used in AC / DC laptop adapters, frameless switching power supply and power charger.
FAN6920MR application:
AC/DC NB Adapters
Open-Frame SMPS
Battery Charger

Fin Evaporator
Wire tube evaporators are widely used in refrigeration product, such as refrigerators, freezers . wire and tube evaporators need to be well ventilated when installed externally to ensure better cooling efficiency. The smooth flow of refrigerant helps to reduce the load on the compressor, saving energy and extending its service life. The structure is welded with steel wire using powder painting.Evaporator for wire tube are used in commercial freezer and visi-cooler too . We may supply wire tube evaporators according to customers' drawings or samples.
