1. A pair of finished speaker protection boards, equipped with 4 pieces of 8MM inner hole soldering pieces, which will not scratch the circuit board when tightening the screws. 2. Made of high-quality KB board, 16A British imported oko silver-plated contact high-current relay, high-current double-sided wiring. 3. Beautifully crafted, the pictures taken by mobile phones look better than the pictures. The photoelectric isolation protection can share one power supply with two boards. Generally, the discrete protection board needs 2 independent AC power to isolate the ground wire. (Most transformers do not 2 sets of low-voltage independent output), otherwise sharing a set of windings will easily cause common ground noise. The power amplifier output by the BTL of this board can also be used directly. 4. The protective action voltage is about 1.4V, the power-on delay is about 6 seconds, the power supply voltage is AC 10-20V, the board size is 4.8×5.1cm, the installation hole distance is 2.2-3.3cm, and finally pay attention, because the electrolytic capacitor The error of the value is usually 20%. This error is relatively large. The difference in capacitance will also affect the different charging time, which will affect the problem of asynchronous connection between the left and right channels. (Asynchronization is usually one second Within), the split-type speaker protection board usually has the problem of not being connected synchronously, and friends who ask to be connected synchronously should not buy this.
