Acrel DJSF1352-RN-6 Din Rail DC Energy Meter
Acrel DJSF1352-RN-6 Din Rail DC Energy Meter
General
Acre DJSF1352-RN-2 rail-mounted DC energy meter is primarily designed for DC charging stations, telecommunications base stations, photovoltaic systems, and other applications. This series of devices measures voltage, current, power, and positive and negative energy in the DC power system. The measurement results can be displayed locally and connected to industrial control devices and computers to form a measurement and control system.
