ZES ZIMMER LMG600 精密功率分析仪系列可在严苛的测试应用中提供高精度功率测量。双路径架构支持最高 10 MHz 的同步宽带和窄带分析。分析仪提供可配置的功率通道和外部传感器,能够精确测量低功率系统、复杂的多相系统以及高功率系统。
10.1" 触摸屏配合直观的用户界面、内置数据记录功能和自定义菜单,可简化操作流程并缩短设置时间。无论用于研发、验证还是认证测试,分析仪均可提供一致且可追溯的测量结果,实现精准的功率分析。
根据需求配置所需精度
不同测量任务对精度和带宽的需求各不相同。LMG600 系列提供 S、A、B、C 四种通道类型,可在同一主机内灵活搭配。其中,S 通道支持 0.015% 交流测量精度和 10 MHz 带宽,C 通道则适合低频测量应用。您可以根据应用需求灵活配置仪器,避免规格冗余,同时确保关键测量环节满足性能要求。
通道配置灵活
单次测量同时采集宽带和窄带数据
传统功率分析仪往往无法兼顾抗混叠保护和宽带信号保真:启用抗混叠滤波器会损失宽带信号信息,禁用滤波器则可能导致 FFT 分析出现混叠误差。LMG600 系列通过每个通道配置两个独立的模数转换器,解决了这一难题——一路采集未经滤波的宽带信号,另一路采集经过抗混叠滤波处理后的窄带信号。两条路径并行工作,可基于同一输入信号同时提供 RMS 值、谐波和 FFT 分析结果。
双路径架构
用户界面满足具体的应用要求
根据具体应用需求自定义视图:选择需要显示的电气参数和 I/O 变量,在屏幕上自由布局,并添加接线图、照片或品牌标识等图形元素。 通过/失败指示器以及用于输入 DUT 特定参数的输入字段均可直接嵌入视图中,从而打造直观易用的测量环境,即使经验较少的操作人员也能轻松上手。
菜单自定义功能
扩展电流测量范围
连接的精密电流传感器 (PCT) 通过集成总线向 LMG600 发送信息,自动传输缩放因子、延迟补偿参数、传感器类型以及上次校准日期等数据。LMG600 系列功率分析仪还可直接为传感器供电,无需配置独立电源。直接测量和基于传感器的测量结果保持一致,无需手动微调即可获得准确结果。
PCT 传感器与连接方式
联通功率分析与汽车应用领域
LMG600 系列可通过 CAN 总线直接共享多达 128 个测量值和变量,包括电压、电流、功率、转速、转矩和温度等。CAN 接口支持双向通信:LMG600 不仅可以发送数据,还可以响应接收到的 CAN 消息,并提供多达 128 个触发条件,可根据外部事件启动记录、切换量程或开始数据记录。无需中间件,也无需手动对齐数据。
LMG600 CAN 菜单
端到端标准合规性评估
LMG 测试套件可引导 LMG600 按照以下标准完成 EMC 一致性测试: - IEC/EN 61000-3-2/-12(谐波) - IEC/EN 61000-3-3/-11(闪烁) - EN 50564/IEC 62301(待机功率) 测试套件支持在线和离线运行,可与符合标准要求的交流电源配合使用,并导出包含完整可追溯信息的测试报告。相关标准若有更新,也会在颁布后及时纳入测试套件。
LMG 测试套件
机械和环境数据实现精准同步
可选的 PSI 提供快速模拟输入、开关输入和输出、转矩/转速/频率输入以及 32 路模拟输出,所有信号均与功率通道实现同步。可在测量电压和电流的同时采集转矩、转速、温度和压力等参数。外部设备可根据测量值直接触发或控制。
突破七通道限制
多台 LMG600 可通过同步电缆连接,构成一台虚拟功率分析仪,并自动实现测量周期、系统时间、瞬态触发事件以及能量积分状态的同步。即使扩展至八个或更多通道,所有主机之间的测量结果始终保持一致,无需人工进行数据对齐。
覆盖从微安到 32 A 的电流测量范围,无需切换量程
IEC 62301 和 EN 50564 标准合规性测试要求在各种负载条件下对被测设备进行连续监测。LMG600 系列提供 500 µA 至 32 A、3 mV 至 1000 V 的连续动态范围,以及 18 位分辨率和最短 10 ms 的测量周期。通过一次不中断运行,即可完成待机和满载状态的特性表征,并在接近量程下限时仍保持 0.015% 的基本精度。
