Description

PMC-D721MD DC Multifunction Meter


Device Introduction
  • The PMC-D721MD DC Multifunction Meter is CET’s latest offer for the low-cost DC metering market. Housed in an industry standard DIN form factor measuring 72x72x71.8mm, it is perfectly suited for industrial, commercial and utility DC metering applications.
  • The PMC-D721MD complies with Class 0.5 kWh Accuracy Standard and features quality construction, multifunction measurements and a bright, easy to read LCD display. The PMC-D721MD comes standard with two Front Panel LED indicators for Energy Pulsing and Communication. It provides two Digital Inputs for status monitoring and two Solid State Pulse Outputs for kWh Energy Pulsing applications. The standard SOE Log records meter events such as power-off, setup changes and DI operations in 1ms resolution. With a standard RS-485 port and Modbus protocol support, the PMC-D721MD becomes a vital component of an intelligent, multifunction monitoring solution for any DC Power and Energy Management systems.
