频率范围 : DC, 40～440Hz。
峰值因素可调范围 : 1.4～5.0。
功率因素可调范围 : 0～1 超前或落后（-1～1）。
高达八台的并联可达 90KW 及三相△或 Y 的负载同步控制。
可外部电压控制 定电流、线性定电流、定电阻、定电压、定功率等工作模式
过电压警示、过电流、过功率、过温度保护。
GPIB/RS232/LAN/USB 控制之介面功能。
可储存/呼叫 150 种电子负载状态设定，节省测试时间。
支援带载开机；先设定Load ON 便可支持带载开机，逆变器或不断电电源开机时便直接带着所设定负载电流开机，用来验证Inverter连接电器时启动是否稳定。
支援抽载与卸载角度控制；吃载卸载角度控制，0-359度全范围都可设定，用来验证实际电器插拔时，Inverter输出电压暂态反应是否稳定，Overshoot/Undershoot 是否在容许范围内。
支援正半周或负半周抽载；用来验证实际电器只有正半周或负半周负载电流时，Inverter 输出电压是否维持稳定。
支援SCR/TRIAC的电流调变波形，90度Trailing edge及Leading Edge。
