DTSY866 Three Phase Four Wire Electronic Prepaid Watt-hour Meter (LCD display-DSM866CY)

APPLICATION

DSM866CY three phase four wire electronic prepaid energy meter,LCD display.

This meter has prepaid function, users should purchase electricity by IC card first then to use the power. This meter is the best way to solve payment-collect problem. It has many functions such as anti-tampering, load control, management of energy consumption and users’ information, etc.

The meter is used to measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net.

The meter adopts LSI (Large-scale Integration) and SMTmanufacturing technique,the key components all adopt long life type.

The meter is widely used in office buildings,shopping malls,residences,airports and metro,etc.

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, 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.
