PMC-352-D DIN-Rail DC Energy Meter

Overview：
PMC-352-D DIN-Rail DC Energy Meter is CET’s latest offer for the low-cost DC metering market. Designed in a compact DIN form factor measuring 36x65x90mm, it is perfect for DC metering application in a space-limited environment. The PMC-352-D comes standard with 3xCurrent Inputs, 4xNTC Inputs for temperature monitoring and 3xDI for status monitoring. It also optionally provides 1xIresidual Input for Residual Current measurement. 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 optional LoRa supporting the Modbus RTU protocol, the PMC-352-D becomes a vital component of an intelligent, wireless, multifunction monitoring solution for any DC Power and Energy Management systems.

Typical Applications：
• DC Inverter, DC Panel Metering and DC Charging Station
