Microchip - MCP39F511A功率监控IC

利用Microchip的双模功率监控IC最大限度提高系统性能 实时测量直流和交流电源功率,并且精度达到行业领先水平的单颗IC。

在同时使用交流和直流电源的系统中,实现双模功率监控传统上需要多个IC才能保证卓越的性能和准确性。越来越多的应用,例如太阳能逆变器、智能照明和云服务器通常使用双模式来保持安全运行,使用交流电作为主电源,直流电作为备用电源,或者反过来。为了优化性能,降低此类系统的开发难度,Microchip Technology Inc.(美国微芯科技公司)推出灵活的双模功率监控IC,在测量交流和直流功率时,能在宽达4000:1的范围内,精度达到行业领先的0.1%。将功率计算和事件监控融入到一个IC中,降低了材料成本,缩短了固件开发时间。
