本文总结了10点精密程控电源的主要技术指标,具体如下:
  
  1、交流电压输出
  
  调节细度:0.05%RG
  
  准确度:优于±0.1%RG
  
  稳定度:优于±0.03%RG/1min
  
  失真度:优于0.1%(非容性负载)
  
  输出功率:额定每相15VA
  
  满负载调整率:小于±0.03%RG
  
  满负载调整时间:小于1mS
  
  输出范围:0V~420V
  
  档位设置:0V~140V、140V~280V、280V~420V,自动档位切换
  
  温度漂移:±15PPM/℃
  
  长期稳定性:±100PPM/年
  
  2、交流电流输出
  
  调节细度:0.05%RG
  
  准确度:优于±0.1%RG
  
  稳定度:优于±0.03%RG/1min
  
  失真度:优于0.1%(非容性负载)
  
  输出功率:额定每相15VA
  
  满负载调整率:小于±0.03%RG
  
  满负载调整时间:小于1ms
  
  输出范围:0A、1mA~10A(20A)
  
  档位设置:0A~0.2A、0.2A~1A、1A~5A、5A~10A,自动档位切换
  
  (可定制:0~1A、1A~5A、5A~10A、10A~20A,自动档位切换)
  
  温度漂移:±15PPM/℃
  
  长期稳定性:±100PPM/年
  
  3、功率输出
  
  准确度:优于0.1%RG
  
  稳定度:优于0.03%/1min。
  
  4、相位
  
  调节范围:0~359.99度
  
  分辨率:0.02度
  
  准确度:±0.05度
  
  5、频率
  
  调节范围:40Hz~65Hz
  
  分辨率:0.005Hz
  
  准确度:±0.005Hz
  
  温度漂移:±1PPM/℃
  
  长期稳定性:±4PPM/年
  
  6、功率因素
  
  调节范围:-1~0~+1;
  
  分辨率:0.0005;
  
  准确度:0.001。
  
  7、工作电源
  
  220V,AC50Hz±5%。
  
  8、谐波输出
  
  3050可以准确输出2~22次谐波,各次谐波可以任意组合叠加在一起同时输出,但是输出谐波时总的谐波含有率之和不要超出下表所出的限制。
  
  3050在输出谐波时带载能力将会减小一半,为了保证可靠准确的谐波输出,请确保负载不超过额定值的二分之一。尤其是电压输出,因为电压输出经常是要作为被检装置的电源来使用的,其上的功耗会较大。
  
  9、带容性负载能力
  
  标准源的电压输出经常也是仪器或各种仪表的供电来源,因此其负载可能有容性部分,比如各种滤波电容。负载的电容最大值如下表,超出表中所列可能会引起输出自激振荡而导致输出保护。
  
  10、体积和重量
  
  三相程控精密测试电源
  
  体积:421mm×380mm×160mm(长×宽×高);
  
  重量:≤18kg。
  
  环境条件
  
  工作温度:0℃~40℃;
  
  相对湿度:≤85%;
  
  储存条件:-30℃~60℃。
