PURPOSE:To obtain an output of 12V battery specification (8-16V) from an input voltage of 24V battery specification (16-32V) by providing the 1st and the 2nd resistors for voltage reduction and turning on and off the current flowing through the 2nd resistor. CONSTITUTION:When the input ...
if the volts and amps are not precisely in phase you have to calculate the watts by multiplying the volts times the amps at each moment in time and take the average over time, i.e. the integral of V*A dt over a full cycle. The ratio between the VA (i.e. rms volts time rms amp...
通过调整PWM的占空比来调节输出电压,模块尺寸小,易于应用在不同的地方。 模块工作电压:DC 12V-30V,(电源功率要求:大于100MA) PWM信号接收频率范围:1KHZ-3KHZ PWM信号输入电平范围: 峰峰值4.5V到10V电平,跳针插在5V处。该类电平信号主要针对常规的工业控制卡(如MACH3板卡)5V的CPU接口。 峰峰峰值12到24V电平,跳针...
