4500系列
主要特点
频率带宽: DC∼20kHz
高输出电压 : ±200V
直流(CC/CV)、交流(CC/CV)四种模式 *
* CC:恒电流、CV:恒电压
两台串联使用输出电压可以增大到两倍。
将4520(2kVA)与功率增强器4521(2kVA)连接,可以使功率提高到zui大10kVA。
装备遥控端子
补偿输出电缆下的电压下降。
也适用于连微小电压下降也不能忽视的精密要求。
Vcc控制
控制内部的直流电源电压(Vcc),提高电源的使用效率,始终确保大电流的输出。
详细介绍
4500系列是能够以直流∼20kHz输出±200V的功率放大器。除了正弦波之外,还能够游刃有余地输出富含直流和谐波分量的信号。
根据输出功率不同,有从250VA到2kVA的四种机型的产品系列可供选购。另外,如果与增强器一起使用,以2kVA为单位功率zui多可增加到10kVA。
