  产品描述
   
  Sourcing the on-playing music as signal then calculating the instant resistance of load based on real-time analysis of the output voltage and current.When the resistance is less than 1.6ohm,soft protection launches to limit the driving current and recovers current in 5 ms after the failure removed.The relay is kept in connected through protection just avoid contact destruction.
Independent detection on the signal above 3KHz in the output.Once it exceeds 40V in 0.5s the protection program launches to lower the output below 40V to levitate the damage to HFdrivers.

IN THE SOLUTION TO LINEAR AMPLIFIER BASED ON LINEAR POWER SUPPLY,THE FOLLOWING INIOVATIVE TECHNOLOGIES PUT THE POWER-TO-WEIGHT RATIO AND POWER-TO-VOLUME RATIO TO A NEW, UNEXP ;ARED LIMIT:

1. Less heat loss due to accurate power allocation

2. Unique power supplying program lower the requirements of power supply

3. Select material and appropriate production technology maximizing the turnout of adapter

4. Ideal radiator structure improving heat sinking so that a smaller and lighter radiator can dissipate heat far faster and more efficiently
