It is easy to generate AC students. If you do not understand the situation, you will be misled by random evaluation, saying that you must change it to meet the signal to noise ratio.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/u\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"color: #000000;\"\u003e\u003cspan style=\"font-size: 18.0px;\"\u003e\u003cspan style=\"color: #0000ff;\"\u003e\u003cstrong\u003eHigh sensitivity, low contact internal resistance, can ensure the use of 200WX2 (2-8) ohms two-channel power amplifier, can also be parallel touchpoint, used in 400W power amplifier\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"color: #000000;\"\u003e \u003c\/p\u003e\n\n\u003cp style=\"color: #000000;\"\u003e \u003c\/p\u003e\n\n\u003cp style=\"color: #000000;\"\u003e\u003cspan style=\"font-size: 18.0px;\"\u003e\u003cspan style=\"color: #cc0000;\"\u003e\u003cstrong\u003e\u003cspan style=\"background-color: #ffd966;\"\u003eBy the way, regarding the installation of protection for the 1969 power amplifier, the 1969 power amplifier has a large capacitor output. It has a charging and discharging process. Normally, the board closes with a delay of 3-4 seconds. 1969 requires more than 1 minute, but this is very simple. The 1969 output terminal can be closed in a few seconds with 1K resistor discharge, and other power amplifiers do not need to be changed\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"color: #000000;\"\u003e\u003cspan style=\"font-size: 18.0px;\"\u003e\u003cstrong\u003e\u003cfont color=\"#ff0000\"\u003eThe lifespan of Omron is also several times that of domestic electrical appliances.\u003c\/font\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"color: #000000;\"\u003e\u003cspan style=\"font-size: 18.0px;\"\u003e\u003cfont color=\"#ff0000\"\u003eFeatures:\u003cbr\u003e\n1 UPC1237 as the core device, with power-on delay, DC protection, power-off impact prevention and other functions\u003c\/font\u003e\u003cbr\u003e\n\u003cfont color=\"#ff0000\"\u003e2 Using a fully sealed high current relay as the core device is not afraid of touchpoint ignition and oxidation\u003c\/font\u003e\u003cbr\u003e\n\u003cfont color=\"#ff0000\"\u003e3 Use 7812 as voltage regulator, wide power supply range, up to any range from AC12V to AC24V\u003c\/font\u003e\u003cbr\u003e\n\u003cfont color=\"#ff0000\"\u003e4 lines are simple and reliable.
