Product Description:


DDSY866 Single-phase Electronic Prepaid Watt-hour Meter is intelligent all-electronic watt-hour meter

produced by our company with the latest microelectronic technology. With IC card as electricity purchase media supported by computer management automation software and hardware technology of electricity charge, it has a variety of functions as energy metering, electricity cost management, load control,collection of electricity use information, etc. At the same time, it realizes power management system of purchase before use, making energy commercialization come true. Moreover, the watt-hour meter is equipped with RS485 and IR infrared full-automatic centralized meter-reading interface, providing a more favorable approach for instant collection of electricity consumption of user prepaid meter. This meter applies to three-phase AC active energy with a measured rated frequency of 50Hz or 60Hz.This meter applies to the fixed installation indoors with an environment temperature no higher than -30--+85℃ and relative humidity no higher than 85%, and no corrosive gas, dust, sand, fungi or insect in the air

Q:Gas / Electric hybrid - electrical accessories?
1 Yes there is a seperate battery for auxillaries and a seperate battery that runs the electric motor/charger. 2 the alternator that runs the auxillaries is a normal 60 to 90 watt unit. It cannot charge the batteries that drive the car. 3 no differant than addind to a regular car.
Q:Are surge protectors really necessary?
Most electronics or electrical devices in the average home only have fuses or circuit breakers as safeguards. They are meant to protect your electrical wiring or prevent fires, not protect the equipment. An electrical surge or spike (they are different things) won't necessarily trip a fuse or circuit breaker, and even if it does, the damage to your equipment may all ready have happened. A surge protector is designed to handle and dissipate this type of event and protect the equipment.
Q:is electronics engineering a promising field of study?
It's pretty booming right now, and probably will be for the next couple of decades at least. As far as possibilities go, what are you looking for? Some EE's start their own companies and make millions. It's as much as what you make of things as it is about hopping on the right train to take you where you want to go. The downside of engineering has to be the pressure and the deadlines. Marketing and money drive engineering. And the market doesn't want to wait forever for the next gismo. Your design has to be finished by a certain time or else the whole bridge project gets held up, etc.
Q:How do u protect a 220-volt equipment from getting destroyed by electrical voltage fluctuations?
Best thing to do is use a surge protector and if the equipment is costly enough use one voltage stabiliser/CVT/UPS in addition.
Q:15Y Armament/Electrical/Avionics Repairer?
This Site Might Help You. RE: 15Y Armament/Electrical/Avionics Repairer? I'm enlisted and my MOS is 15Y (Armament/Electrical/Avionics Repairer). I'm going to BCT on 20100203 and AIT right after at Ft. Eustis. I'm excited about learning about armament and avionics. I feel proud and privileged to have a chance to work on the numero uno attack helicopter in the
Q:do i need a 2 pin or 3 pin plug in canada?
Its a 3 pin plug herenot to worryjust get your stuffyou can buy a converter herealso electricity is 110V. so be mindful of that as well.cheers
Q:Will I get interference if I run an electrical wire and speaker wire through the same conduit?
You best safe guard is to use UTP for the wiring - that way you will be sure there will be no hassles
Q:How long would the electrical power lines and other equipment last if no one kept them repaired?
The lines are mostly copper or aluminum for the wires themselves. The towers are steel. They would last for decades easily. But lines that run from transformers to homes or neighborhoods could fail earlier. Look at what happens with ice storms in New England. Substations and transformers would last quite long also. But the power stations would last for anywhere from hours to weeks, depending on the degree of automation, and on chance. .
Q:Are electrical systems on spacecraft grounded?
We do not ground all electrical equipment. Much of it is double insulated. Grounding simply connects the chassis to Earth, so that if there is an electrical fault that makes the chassis live this is short to Earth and a person, who we might expect to be standing on Earth and not hovering, will hence be at the same potential as the chassis. The actual circuit is not grounded - its return path conencts to neutral. Precisely the same principle can be used in space, but in light of the fact that people in space may actually be floating, double insulation is safer.
Q:What kind of walt of electricity use in U.S.A?
120 volt / 60 Hz. Adapter kits should be readily available.
