Main technical features

The electric meter adopts advanced metering and control chips (industrial grade), modular structure design, and strong anti-interference ability.

The communication circuit of the electric meter adopts lightning protection design, and the signal adopts photoelectric isolation. The communication circuit and the internal circuit of the electric meter are electrically isolated to minimize the damage of lightning strikes to the electric meter.

The interface of the electric energy signal acquisition module adopts a computer specific interface, which has undergone special processing to ensure reliable signal transmission.

The metering circuit, communication, and display circuit adopt a dual CPU structure, with one CPU responsible for metering and the other for communication, display, and indication. Communication does not affect metering.

The internal strong and weak electricity are isolated by galvanized shielding plates, which can reduce the interference of strong electricity on weak electricity signals.

The electric meter adopts a dedicated three-phase energy metering chip, which has a short measurement cycle, high accuracy, stable performance, long service life, and effectively prevents electricity theft.

The internal power supply is three-phase, but there is a phase loss in the power supply. The electricity meter is still working as usual.

The incoming terminal of the electric meter adopts dedicated wiring terminals, which have strong current carrying capacity and are convenient for on-site construction.

※ Data Security: Various data parameters of the electricity meter are encrypted using algorithms to ensure data security.

※ It can simultaneously measure and detect 36 households (single-phase) or 12 households (three-phase), as well as any combination of single and three-phase for households below 36.

※ It has a power phase loss indication function.

※ Post payment (positive counting) function: Users can use electricity first and pay later.

※ Public electricity allocation function: Public electricity consumption, such as public lighting, can be allocated by user or electricity through management software. (This function requires the electricity meter to be connected to the network to achieve)
