(an ON Semiconductor company) is a semiconductor manufacturing company with excellent power device technologies, such as miniaturized packaging, high-efficiency switching, and high-density packaging, as...

Pay attention to the installation of UPC1237. If the word is asked outward, there will be no delay after installation. The normal delay is 3 seconds. The board adopts double-sided immersion gold double-sided, and the transmission internal resistance is low. High sensitivity, low contact...

大功率功放使用的软启动控制板，需要配自锁开关使用，板载6W电源变压器工作更加稳定可靠，最大电流30A 板上接线说明： IN：220V电源输入 OUT：220V输出（去接机内电源变压器） KG：接开关机控制开关（要求用自锁开关） 软启动板尺寸：100mmx100mmx38mm高 成品板净重：约305g  整流桥和4个电容构成交流滤波电路，整流桥需要接机箱底板散热  

  功放使用的软启动电源板，需要配自锁开关使用，可以同时控制两组输出接变压器，最大功率1500W。使用12V的 大功率继电器，以及NTC电阻 市面销售带功放软启动带高压电容都省略了放电电阻，这样导致软启动电路板在拔掉电源插头后依然带电极其不安全，导致插头带电容易伤害家人，本电路板是带有安全放电的电阻可以放心使用 音响软启动，非电机软启动，非电机软启动，非电机软启动 【适用范围】适合高档音响电源输入用，或其他大启动电流机器应用。使用功率适合在2400W以内。长期负载最好在1400Ｗ以内！ 电源电压适应范围：交流150V到280V。 主要特点： 软启动板功能是降低开机瞬间冲击电流，以减少机器对电网的影响和延长开关的寿命。有效的保护机器，防止过大的开机电流。 此板无需辅助电源，只有2个接线端子，一个接电源输入（之前接个开关控制），一个输出接负载，使用非常方便。          PCB尺寸：80mm x 80mm         安装孔尺寸：70mm x 70mm         输入电压：220V交流      最大输出功率：1500W    

The new version on 2014-6 5th. Before many comments, the old board must be replaced by Japanese Omron. So the new version is all standard with Japanese Omron relays by default. The layout is better than the previous version and the installation area is...

There are two types of driver boards. The A version drives the watch head with LED, and the B version drives the watch head with tungsten wire. The wiring methods of the two watch heads are the same, but there are 3 resistors that...

  Power filter board 2A 4A 18A EMI filter, sound booster, filter socketThe kit needs to be welded, plus 3 yuan for replacement welding. PCB is a double-sided gold PCB with lower internal resistance and better electrical conductivity adoptImported Italian AVFilm capacitors, the effect...

The LM317 alone can meet the needs of general equipment, but for higher accuracy and better thermal stability, adding the TL431 as a reference regulator increases the voltage by 1-2 levels, the noise is lower, and the ripple is lower. The cost is not...

The LM317 L337 alone can meet the needs of general equipment, but for higher accuracy and better thermal stability, the addition of TL431 as a reference regulator increases the voltage by 1-2 levels, the noise is lower, and the ripple is lower. The cost...

       The ground wire of the two linear regulator boards isIt is completely independent and separated, so it can also be connected to a double-bridge positive and negative power mode, or a 2-way positive voltage mode. The display board is not brought,...

The simplest high-current voltage stabilizer is to use LT1083 as the core, but the new licensed goods are close to 50, and the refurbishment and disassembly do not count. After the current exceeds 5A, the actual ripple is much larger, and the voltage drop...

The kit needs to be soldered by itself: This power board uses 4Original imported IRSchottky30CPQ150(30A150V)Equivalent to a 120A bridge stack! Schottky is characterized by fast speed and small internal resistance (naturally, the voltage drop is also low).Therefore, it is more abundant in low frequency...
