10(40)A LCD Display Single Phase IC Card Prepaid Energy Meter with Power Display
1. General:
The DDSY150 type three-phase electric pre-paid watt-hour meter is a new type of IC card pre-paid meter, which has such function as power metering, load control and customer information management. It is an ideal product when refor-ming electric-use system, achieving electrical energy to commercialize, setting charge and adjusting load stage in the electric network.
2. Function and Features:
2.1 Active three-phase electric power metering, no subject to adjust in terms of long working;
2.2 Three phase power supply can assure accurate metering in case of cut off in one line (each line of the three-phase & three-line or two lines(any two line of the three- phase & four-line);
2.3 Indicative function for phase loss or voltage indication;
2.4 The signal will display after it test;
2.5 Each user(meter) responds to a card, well protect from forgery;
2.6 Once the remanining electric power quality is approaching the alarming power quality, the digital tube should be lighted to remind user of timely purchasing;

Safety precautions:
＊ Use only isolated tools.
＊ Do not connect the meter to a 3 phase - 415V AC - network.
＊ 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.
