2. FUNCTIONS AND FEATURES
Meter casing ABS anti-flaming(PC optional), with transparent PC window, which is anti-UV molded overall. Meter terminal block is made of bakelite which is moisture-resistant, fire-retardant, high temperature molded.
Highly reliable special ESD design for the IC card entrance, which can bear the attack of 8kW static electricity.
LCD 6+2 digits display, may select LED & cyclometer double dislay.
One meter has one card, the card has re-charged function.
Purchase electricity before using. The power supply would be automatically cut-off once the available energy consumption purchased is used up.
The meter can set alarm kwh quantity, and indicated by alarm LED or automatically cut-off when the alarming kwh quantity near reachs, it's in order to remind the user to re-charge power in time.
Load control, over-load switching automatically.
Data copying function makes the power department easily to manage. The data can be stored for more than Ten years without power supply when meter turn off.
Large-capacity magnetic latching relay control, measure energy in security mode.
Single direction measures three phase four wire active power consumption. It is nothing with direction of the Flow of load current, complying with standard IEC62053-21, IEC62052-11.
Directly connect operation or through CT or PT & CT.
Anti-tampering functions are available.
Standard configuration short terminal cover, which is helpful to reduce installation space and make it convenient
To install. May select extended terminal cover, which is for protecting the safety of using electricity.
