DSM228CY Single-phase Two-wire Electronic Prepaid Active Energy Meter (LCD Display)
APPLICATION
DSM228CY single phase two wire electronic prepaid energy meter,LCD display.
This meter has prepaid function,for the users pay firstly,use second,This meter is the best way to solve payment-collect problems,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 single phase two wire AC electricity net.
The meter adopts LSI (Large-scale Integration) and SMTmanufacturing technique,the key components
all adopts long life type.
The meter has the features of good reliability, small volume, light weight, specious appearance, etc..
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 material 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.Once the available energy consumption purchased is used up, power supply would
be automatically cut-off.
♦The meter can set alarming 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 of re-charge power in time.
♦Operation indicated by pulse LED.
♦Load control, over-load switching automatically.
♦Data-copying function makes the electricity department easily to manage.the data can be preserved for more
than ten years without power supply when interrupting.
♦Large-capacity magnetic latching relay control, measure energy in security mode.
♦Single direction measures single phase two 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.
♦Direct connect operation,there are two types wiring you may select.
♦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.
