DESIGN FEATURES

1. Advanced IR class D driver IC designed.  
2. Aluminum PCB design, it is conducive to rapid heat 
    dissipation of SMD power components.
3. Adopt EE type high frequency transformer with 
    high reliability.
4. Independent high/low level signal input interface, 
    with high level signal automatic power-on.
5. Multiple ways of protection(over-voltage/over-
    current/thermal/short circuit).
6. Compact sized dimensions, high operating efficiency.
