Description

PMC-512-A AC Multi-Circuit Power Monitor


Device Introduction
  • PMC-512-A is CET’s latest offer for the economical multi-circuit monitoring of Data Centers, Telecom Base Stations, Industrial & Commercial Buildings. Housed in a compact DIN Rail Mount enclosure, the PMC-512-A is perfectly suited for high-density metering applications.
  • The PMC-512-A features quality construction with multifunction and Class 1 Energy Measurements. The PMC-512-A comes standard with a built-in LCD display, 12xDIs for status monitoring, 1xDO for control or alarming. The standard SOE Log records all setup changes, alarms and DI/DO operations in 1ms resolution. With dual RS-485 as standard feature supporting Modbus RTU, the PMC-512-A can easily be deployed in a stand-alone system with an optional 7" touch-screen HMI that supports up to 32 devices over a RS-485 network, or simultaneously with a centralized monitoring and control system for an AC power distribution network.
