4502,4505,4510,4520A,4521,精密功率放大器
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，可以使功率提高到最大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。
精密功率放大器
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为单位功率最多可增加到10kVA。
