功能和特点

1) 能够提供两种控制模式,能够适应不同的应用环境:

通过键盘设置。

通过RS23接口由计算机控制。

2) 多种保护功能。考虑市电状态、冷却状态、模块工作状态多因素,对电源提供全面保护,并且在液晶屏上直接显示故障状态,方便用户检查原因。

输入电源掉电保护(内部保护吸收感性负载反灌能量)

内部过热保护(不能打开输出,如果发生在工作中自动关闭输出)

模块过流(自动降流,不可控过流则关闭输出)

模块过功率(自动限制输出电流,不可控过功率则关闭输出)

3) 两种输出方式

电流模式:直接设定负载上加载的电流

磁场模式:直接设定磁铁或者线圈中的磁场大小

注意:磁场模式需配合我公司自主研发的高精度内置高斯计才能进行磁场模式的工作

4) 双极性输出    

输出电流、电压四象限工作(适合感性负载)

输出电流变化速率0.0007~0.5 FS/S(FS为额定最大输出电流),对电抗性负载,电源自动根据电流、功率作调整限制输出速率。

非输出开关换向,电流可以平滑过零点。

5)P作为一个系列,可根据应用负载的不同选择不同的输入输出参数

电流稳定度50ppm/h(标准型)或者10ppm/h(高稳定型)可选

输出功率0.5kW到15kW

输出电流5A到120A
