DJSF1352-RN DIN-rail DC energy meter

DJSF1352-RN dual input DC energy meter is mainly designed for telecommunications base stations, DC charging piles, solar photovoltaic and other applications. This series of meters can measure voltage, current, power and positive and negative energy in the DC system. In the actual use of the site, it can measure the total energy, and can measure the energy within the specified time period. The detection results can be used for local display and can be connected to industrial control equipment, computers, measurement and control systems.

  • RS485 communication interface
  • Support Modbus RTU protocol
  • Relay alarm output and digital input function
  • Setting the ratio, alarm and communication parameters via one button
  • Event recording of switch, programming, maximum and minimum value recording
