PMC512D DC Multi Circuit Power Meter

The PMC512D DC Multi Circuit Power Meter is CET’s latest offering for Telecom Base Stations, Renewable Energy, Commercial Building, and Industrial Automation applications that demand Direct Current (DC) multi-circuit monitoring. The PMC-512-D is ideal for applications requiring high-density metering because it is housed in a small metal box. The PMC-512-D is a high-quality device with one mains input, up to 12 branch circuit inputs, multifunction and high-accuracy measurements, and an optional color touch-screen HMI. Thirteen digital inputs for status tracking, one relay output for control or alarm, and one analog input for temperature measurement or other analog input applications are all included with the PMC-512-D as standard.
