Multifunctional Electric Power Parameter Meter
The ISPM25 series multifunctional power parameter meter provides cost-effective measurement solutions for public/commercial buildings, industry, energy and infrastructure, power grids, and utility customers.
The ISPM25 series is equipped with a standard RS485 communication interface and features multiple IO expansion functions, which can be flexibly selected as needed.
Widely used in distribution cabinets, SCADA systems, energy management systems, substation automation, distribution network automation, community power monitoring, industrial automation, and smart buildings.
Current and voltage accuracy of 0.2 class, power accuracy of 0.5 class, meeting the needs of high-precision monitoring, internal sub-metering, and energy management applications.
The 85*85mm and 68*68mm cutout sizes make it very suitable for various installation methods.
Easy installation, simple wiring, low engineering workload, programmable on-site, capable of networking with different PLCs and industrial control computer communication software.
