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.
