三菱高性能矢量控制变频器FR-A8TAT全新现货供应

商品详情

FR - A820 - 03160 - 2 - 60 是三菱电机 FR - A800 系列中的三相 200V 等级高性能矢量控制变频器，主打中大型工业设备的高精度调速与高可靠性驱动，凭借优异的控制性能、丰富的功能配置和强悍的环境适应性，在多个重工业及通用工业领域占据重要地位，以下是其超千字的详细介绍：

核心基础参数
- 功率与电流规格：该机型针对不同负载场景划分了精准的功率和电流标准，超轻负载（SLD）下额定功率 75kW、额定电流 316A；一般负载（ND）下额定功率 55kW、额定电流 215A；重负载（HD）下额定功率 45kW、额定电流 175A，这种多负载适配设计能让其灵活匹配不同工业设备的运行需求。
- 物理与电源参数：外形尺寸固定为 465mm×700mm×250mm，重量达 54kg，属于中大型工业变频器规格。适配三相 200 - 240V 交流电源，兼容 50Hz/60Hz 的电源频率，电源电压允许波动范围通常为 170 - 264V，能应对工业电网的小幅电压波动。其安装尺寸与 FR - F700（P）系列基本一致，整流器分离类型除外，极大方便了旧设备的升级替换，无需额外改造安装空间。
卓越的驱动与控制性能
- 高精度矢量控制：作为 FR - A800 系列成员，它搭载高速处理器，强化了实时无传感器矢量控制和矢量控制功能。在无传感器矢量控制模式下，运行频率可达 400Hz，针对 0.4 - 3.7kW 功率区间的电机，能在 0.3Hz 的低转速下实现 200% 的输出转矩，启停时动力强劲且运行平稳。同时支持驱动感应电机和永磁同步电机，适配两种主流电机类型，减少了用户设备选型的限制。若搭配编码器使用，速度控制范围可进一步拓展至 1:1500，满足机床等设备对转速精度的严苛要求。
- 丰富控制功能集成：内置 2 个 PID 运算器，既能通过 PID 控制电机运行状态，还能同步控制外部机器，无需额外配置 PID 控制器，大幅降低系统搭建成本。此外，它还涵盖工频 / 变频切换、挡块定位、防摇控制等实用功能，其中防摇控制能有效避免起重、输送设备运行时的物料晃动，挡块定位则可满足自动化生产线中设备的精准定位需求。
全面的安全与可靠设计
- 多重保护机制：安全防护体系十分完善，包含过电流、过电压、过载、过热等核心保护功能。当电机出现过载运行时，变频器会迅速触发保护指令切断输出，防止电机烧毁；在减速过程中若出现母线电压过高的情况，会通过自身调节抑制泵升电压，避免内部元器件受损。同时支持安全停止功能（SS1/SS2），紧急情况下可快速切断动力输出，保障设备和操作人员安全。
- 强环境适应能力：电路板经过特殊涂层处理，能抵御潮湿、粉尘等恶劣环境的侵蚀，部分衍生型号还具备 IP55 防护等级，可直接应用于车间等粉尘较多的场所。内置 EMC 滤波器，通过新开发的驱动和供电技术，大幅降低电磁干扰，避免对车间内其他精密电子设备的运行造成影响。采用长寿命元器件，设计寿命可达 10 年，强制风冷系统支持 - 10℃至 + 40℃的宽温运行，适配不同地区和季节的工业环境温度变化。
便捷的操作与通信扩展性
- 简易操作配置：可搭载多语言 LCD 参数单元，显示清晰且具备时钟功能，操作人员能快速查看运行参数和故障信息，不同语言设置也方便跨国企业的车间人员使用。同时支持通过 USB 闪存复制参数，批量调试多台设备时无需重复设置，显著提升调试效率。
- 灵活通信接口：标配 RS - 485 通讯接口，兼容三菱变频器协议和 Modbus - RTU 协议，数据传输速度可达 115200bps，能轻松与 PLC、触摸屏等设备组网通信。若搭配扩展卡，还可支持 CC - Link IE Field Basic、Ethernet/IP 等工业通信协议，实现工厂级的集中监控和远程控制。其输入输出点数达 60 点，其中输入 36 点、输出 24 点，输出形式为漏型晶体管，可连接多种外部控制元件和执行器。
广泛的行业应用场景

该变频器凭借强大的综合性能，覆盖多个工业领域。在钢铁业中，适配轧钢设备的驱动需求，低转速大转矩特性保障轧钢过程的稳定；在纸浆造纸行业，能匹配造纸机、收卷机的运行，快速响应生产线速度变化，避免纸张缠绕不均；仓储和航运业中，用于输送带、起重设备时，平稳的启停和运行性能可防止货物滑落；在木材加工、金属制品制造业中，精准的调速功能能适配切割、打磨等不同工序的转速需求。此外，在纺织业的纺纱机、风机水泵等通用机械上，也能通过变频调速实现节能运行，降低企业能耗成本。
突出的节能环保优势

它将节能理念深度融入控制算法，一方面可直接驱动永磁同步电机，这类电机本身相比传统感应电机节能效果显著；另一方面内置励磁控制技术，能降低设备待机功耗 20% 以上。在风机、水泵等变负载场景中，通过调节电机转速匹配实际流量需求，替代传统挡板、阀门的节流控制方式，避免能源浪费，这类场景下通常可实现 30% 左右的节能率，长期使用能为企业节省大量电费开支。
