The power supply efficiency shall be greater than65% under rated input voltage. It will be measured at the typical load and maximum load.

在额定输入电压，最大负载和额定负载条件下，电源的效率大于65%。

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.

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。
