1.Description:
   The horn protection board has the functions of power on delay (about 3 seconds) and DC protection (starting voltage is about 1V). The board circuit is simple, easy to make, and job security and reliable to work. It has LED status display, which lights up when protecting and turns off when working normally. It uses a large current relay, which is suitable for most power amplifier boards. The working voltage is 12-15V, which requires independent power supply and cannot share a winding with other circuits.
 
2.Parameter:
  1>.Work Voltage: AC 12-15V
  2>.Work Temperature:-25℃~85℃
  3>.Work Humidity:5%~95%RH
  4>.Size: 65*40mm
 
3.Note:
  1>.The BTL circuit requires two sets of protection boards (one for each channel)
  2>.The protection board is only suitable for dual power supply amplifiers and cannot be used for single power supply amplifiers.
  3>.Working voltage AC: 12-15 requires independent power supply.
