Thiết bị đo điện thông minh 3 pha 4000A Ethernet Modbus TCP ICP DAS PM-3133i-RCT4000P-MTCP CR
ICP DAS brings the most powerful, cost-effective Smart Power Meters PM-3133i-RCT series that access real-time electric usage for three-phase power measurement. The PM-3133i-RCT series can be applied to the low voltage primary side and/or medium/high voltage secondary side, and enables the users to obtain reliable and accurate energy consumption readings from the monitored equipment in real-time under operation. In addition to its compact size and cost performance, the additional Rogowski Coil CT is suitable for high current measurements from 500A to 4000A, large wire diameters (e.g. busway conductor), and for installation in tight spaces. Built-in AC isolator protection, this means total isolation between the AC measurement side and the control side. It operates over a wide input voltages range 10 ~ 600 VAC which allows worldwide compatibility.
