Introduction
Eastron DCM230 series DC energy meters are designed for measuring and monitoring in DC systems. The din rail DC
energy meters can measure of important DC parameters: Village,. current, power and energy etc. It also support bi-
directional measurement with pulse output. All data in the meter are accessible via RS485 using Modbus RTU. The
meter has two versions working with AC or DC power supply. Input voltage range up to 300, 600, 1000V DC, and
current inputs are flexible with DC shunt and current sensors. The multi-tariff version has a RTC equipped inside, it
can provides multi-tariff information and monthly records.

*when the CT setting on meter is 2000A, the default pulse constant is 10 imp/kWh and it can be set to 10 imp/kWh
or 1 imp/kWh.
*Over-current alarm: Alarm will happened when the current is over the CT1 value set on the meter. The Alarm LED
will stay solid and the corresponding register value will be changed. The user can read this register through
communication to determine whether an overcurrent alarm has occurred.
The pulse outputs can be set to generate pulses to represent Import kWh/ Export kWh/ total kWh.
The pulse output is passive type, complies with IEC62053-31 Class A.
