Description

DJSF1352-RN DC energy meter is designed with double DC input channels. It can measure all electrical parameters, total value, and values in different time periods in DC systems. It can be connected to Hall sensor or shunt, the voltage can be 1000VDC. It has RS485(Modbus-RTU) communication and provides power supply for matched hall sensors. The meter has extra optional function as dual DC circuits monitoring, secondary RS485 (Modbus-RTU); DO/DI function. The meter has been used in many base station projects of American Tower, TASC Towers, Helios Towers, IHS Towers, Orange, Vodafone, Edgepoint.
