Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
PEL-3000系列电子负载具有高速斜率和大功率容量，能够满足SPS（开关电源），直流-直流电源转换器，HEV(混合动力电动汽车)电池测试的需求。
PEL-3000系列拥有单通道，有7种操作模式，CV(定电压)，CC(定电流)，CR（定电阻），CP(定功率)，CC+CV,CR+CV，CP+CV。在CC和CR模式下，它的序列功能可以模拟各种动态负载特性。序列功能允许通过指定的负载电流，上升/下降斜率，电流水平，持续时间和其他参数来编辑负载曲线。
除了USB和GPIB及RS232C的数字接口，还有外部模拟控制接口，该接口允许设置操作参数和监测PEL-3000输出的电压及电流。PEL-3000系列有5种型号，PEL-3021(175W),PEL-3041(350W)和PEL-3111(1050W)，最小输入电压是1.5V。功率可以通过并联加载机来提升，连接4台加载机，功率可以达到9.45KW。
PEL-3000系列具备保护机制，如OPP,OCP,OTP,UVP和反极性保护，它们能显著的提高设备的可靠性。提供RS 232C,USB,GPIB和GO/NG标准接口。对于编程控制，LabVIEW驱动和VB,C,C++示例代码是可用的。PEL-3000系列针对产品设计和生产提供一个快速，有效的解决方案。
