最初购买了一个15V10A的开关电源。
驱动板说明书上写的最大10A。接到驱动板上，把板子给烧了。询问技术人员后说，是一个双端输出这样每个腿就是5A了。 开关电源上不是也有+-15V吗？ 所以现在不知道应该购买哪种电源? 驱动板技术人员发的邮件： A ‘leg’ refers to a hot conductor in an electrical system. Our system contains two ‘hot legs’(sometimes also called the positive and negative rails). The power input should be DC, as you want a steady supply of power to the servo amplifiers. However, galvos, by their nature, are sinusoidal systems so the power outputs going to the motor from the amplifier is alternating. The servos themselves have two generously sized capacitors that provide instantaneous current to the output drives when needed. This reduces the overall power supply demands, which is why you do not need a power supply that outputs 10A. Typically, a supply of 3A – 5A is more than sufficient to run these galvanometers. Again, the customer will have to keep in mind that this is a dual-output supply so it is 3-5A per channel (or leg, or rail, whatever the vendor wants to call it). If your customer was using a linear supply and it was 10A, they put 10A across one leg of the system and likely cooked it. 驱动板要求： 接线图 电源参数：
