The PM-3133-RCT series are the most powerful, cost-effective, advanced Smart Power Meters in the market. PM-3133-RCT Smart Power Meters allows the users to access to real-time electric usage for three-phase power measurement. With its high accuracy (50A), this PM-3133-RCT series can be used to both low voltage primary side and 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. The PM-3133-RCT series monitors equipment with Rogowski Coil CT is "rope-style" Current Transformer, allowing "Easy Installation" features for large window size (55 ~ 105mm) and mechanical flexibility tight spaces.
PM-3133-RCT Smart Power Meters series operates over a wide range of input voltages 10 ~ 500 VAC, allowing universal compatibility. The PM-3133-RCT Smart Power Meters series also has 2 channels relay outputs, allowing it to be linked with sirens or lightings for alarm messages. It also supports Modbus RTU, CANopen protocols for easy integration.
