DC Energy Meter 5+1 Channel (Model: RTDCEM1173-6CH)
The RTDCEM1173-6CH is a 5+1 channel DC energy meter built for accurate DC power measurement in telecom/industrial sites, operating on an 18–62V DC input range. It uses a 32-bit microcontroller with 6-channel Hall-sensor current sensing (200A & 500A), delivers Class 1 (±1.0%) accuracy, and communicates via isolated RS-485/Modbus with optional GPRS/3G/LTE connectivity. Housed in a steel powder-coated body, it offers a web dashboard, event logging, digital I/O, reverse-polarity protection, and remote firmware upgrades for dependable, remotely managed energy monitoring.
