RF/GPRS Three Phase Smart Electric Meter for AMR System with DLMS/COSEM Protocol

Adding more functions and wireless communication features to the basic DTZY 150 type, the DTZY150-M is built as a three phase four wire or three wire electric meter with extended functionalities for a diversity of metrological measurement and AMR AMI deplolyment. It is a tamper-proof rich multi-rate meter completed in a BS 5685 footprint case, mainly used for commercial and inustrial environments.

Main Parameter:

Safety precautions:
＊ Use only isolated tools.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the meter can measure.
＊ Make sure the AC wires are installed correctly before activating the current/voltage.
＊ Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
＊ Make sure the protection cover is placed after installation and has been sealed.
＊ Installation, maintenance and repair should only be done by a certified electrician.
＊ Never break the seals or open the front cover as this might influence the functionality of the meter.
＊ Do not through, drop, kick or other physical violence to the meter as there are high precision components inside that will break or make the meter measure inaccurate.
＊ Do not mount the meter in area's with harm gas, dust, mildew or insects or on unstable surfaces.
