Product Details
1. Introduction
DDS353H-1/2/3 is a single phase DIN Rail meter, 100A, which is a
multi-functional meter for
energy monitoring.
It is only 18mm width, but can support RS485 communication and
comply with DIN EN 50022
standard, which is fit for the power distribution system for
household and commercial.
2. Features and Technical Parameters
2.1 Features
2.1 Features
● It can read grid parameters, analyze the energy quality and
load condition in the certain time
period.
● DIN RAIL (Comply to German Industry Standard ) mounted.
● Only 18 mm wdith, but can achieve 100A.
● Support RS485 communication, Protocol: Modbus-RTU mode.
● Multi-tariff function. The user can set the different time
periods via RS485.
● The meter has Li-battery for RTC. The RTC accuracy is 0.5s
every day.
● Blue backlight, which is for easy reading in dark place.
● Do scrolling display for current(A) , voltage(V) , etc.
● Measure the active and reactive energy accurately.
● 2 Modes for data display:
a. Auto scrolling mode: the time interval is 5s.
b. Button mode by external button for data checking.
● The material of the meter case: PBT resistance.
● Protection Class: IP51 (For indoor usage)
