Description
Din Rail mounted,adopt flame retardant PC material,strong impact and weather resistance, and is suitable for various installation environments. The DC meter has tariff function, built-in clock chip. Clock error accuracy0.5s/day which guarantees the reliability of the tariff function.
Feaures
RS485 communication: used for parameter setting, data reading; DTL645 protocol/Modbus Protocal.
DC metering: using shunt sampling, high measurement accuracy; can measure DCpower, current,voltage.
Alarm function: Over-current alarm: When the current exceeds the CT1 value set by themeter, analarm event occurs, and the alarm light on the electrical surface panel lights up (yellowlight), At the same time, the value of the corresponding alarm status register will change, and theuser canread this register through communication to determine whether an over-current alarmhas occurred.
Display: LCD with backlight ,Support Various parameters display,energy data and Instantaneousparameters.
One channel relay out put (Used for over current cut off ).
Firmware upgrade: RS485 local upgrade.
