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

2. Functions and Features

Q:If i buy electrical equipment from the US and it is delivered to the UK, other than face value and postage.
Thats a reflect of the IO interface. Same with me too
Q:Which of the following statements is NOT true about lockout/tagout?
D is not true - a lock out tage is used whenever applying electricity to the circuit would result in dangerous conditions. When repair work is being done on the circuit equipment for example. Lock out tage are used for more then just electrical too.
Q:Distance that an arc can occur?
That is ok with respect to any possible arc. But there may be other reasons to add insulation. Safety for example. If it's easy to add the insulation, do it. .
Q:Electrical Code question?
the gfci should be as close as possible to the hot tub for safety reasons . to me the breaker in the home panel is not what you want for safety I would discuss this with the hot tub or swim pool sales company before attempting any changes . I am guessing that you recently bought the home and previous owner did the install and did not include the proper electrics [[ consult and change for your safety and the safety of your family .]]
Q:Please help What is it actually meant by 'rated' here in this context? Thanks?
Safety rated by an organization that issues such ratings such as UL or FM
Q:how can i prevent dust from gettingin my electrical equipment?
You could turn your Living room into a clean room, and put on a bunny suit every time you go into it!
