可编程多量程单通道直流电源PSB-1800M
型号:
  • 固纬电子新推出的单组输出、多量程可程控直流电源供应器系列机种。包含400W分别是40V/40APSB-1400L160V/10APSB-1400M800W40V/80APSB-1800L160V/20APSB-1800M160V机种透过串联可实现zui大320V的电压输出;PSB-1800L并联可实现zui大320A的电流输出。是一款具有友善使用者界面的桌上型电源供应器;透过LCD面板及选单式功能选取,可以清楚的显示设置条件及量测结果无需另外查阅使用手册;透过功能键、数字键及快捷键可以轻松完成相关设定,其前端子30A输出能力更能满足于实验室及科学研发单位使用。

PSB-1000不仅提供友善式选单式功能接口,内建之功能更适合产业之应用。由于PSB-1000系列机种提供前面板及后背板输出,方便研发人员取得电源输出。而面板采用选单式功能选取可以让用户很快的熟悉及操作PSB-1000系列,非常适合复杂功能设定需求的现场工程人员及研发人员。其Bleeder功能是可以帮助内部电容器快速放电,免除潜在电荷放电的危险。对于电池的充电应用,可将Bleeder设定为Disable, 避免对充电应用造成影响。而I/V Control功能可依待测物之需求分别调整电压/电流上升及下降速率,除有效降低输出之突波电压及电流外,还可用于对待测物特性量测。CC优先输出模式,可应用于避免涌浪电流在二极管特性负载或LED负载下产生。Sequence Function(SEQ)可以针对相关法关或测试需求,透过Excel窗体完成编辑并加载至机器后,自动执行产生所需的输出波形。常被应用于规划一组连续电源变化来对待测物进行特性评估,如产生一连串电源变化输出来测试对车用风扇所造成的冲击,属可靠性测试应用。另外开机组态设定(Power On Configuration)可以让使用者选择已编辑好的序列式输出(SEQ),设定为开机时自动执行。针对有序列电源供给输出应用需求的生产线,省去每次开机时需重新设定序列电源的人工时间。Voltage Trigger可以让用户自定产生脉波信号,透过决定在输出电源上升的那一个准位及结束在电源下降的那一个准位产生的脉波信号,经由VOLT TRIGBNC接头提供工作电压的输出时间,可应用于自动化测试系统(ATS)。透过Output Delay功能各别设定多组PSB-1000的电源输出及电源输出截止时间可以实现时序电源输出应用。

PSB-1000系列具有多量程(Multi-Range)之输出能力,提供四倍定功率输出满足客户弹性的使用需求。全系列机种及操作范围如下图。
