其能够在不影响额定输出电流的情况下缩小电源，允许减少电容的数量。
This allows a reduction in the number of capacitors, providing a downsizing of the power supply without compromising the output current ratings.
若考虑伺服放大器效率及电源功率等因素，伺服放大器电源电压应取额定输出电流所对应的伺服放大器输出电压的3倍左右为宜。
If the efficiency of servo amplifier is considered, it is practicable that the power supply voltage is about 3 times as large as the servo amplifier output voltage corresponding to rated current.
最大输出电流受到额定功耗的限制。
