1. General
SPD520 DC energy meter is designed for photovaltic system and telecom station. They can collect the current, the voltage, the power, the energy on the DC circuit. And they can justif the current direction to count the energies of different direction.
They all have standard RS485 interface and one alarm (Program setpoint). By STAND30 software, the users may collect SPD DC power meter by computer and store the data in the disc for data searcing and data printing in future. By their 4 front buttons, we may program their shunt ratio and RS485 commnuncation parameter.
They are all designed completely according to EN61036 and EN61010.
