DUAL TRANSISTOR FORWARDER SCHEME:
Adopt advanced power management chip scheme which is mature and reliable for many years Two-transistor forward uses two mosfets. mosfet has small impedance, low loss, high efficiency, low temperature rising.
By applying smd chip technology and smd components,significantly improve product stability, reduce the power supply's weight.
Pure copper winding, secondary winding specially added copper slice as a heat conduction material, effectively control temperature rising.
More coil turns and higher permeability leads to high inductance.Output inductor using sendust as core material. With high inductance,power supply's size is smaller and weight is lighter.
Adopt first order EMI filter circuit to meet EMI requirements and design standard, effectively avoid display interference caused by power supply.
With built-in separate overload, short circuit protection circuit to ensure that in case user's system is abnormal, no safety problems occurs, neither damage occurs to the system. Provide stable, reliable and safe power supply to customers.
