ZY1502 DC LIMIT METER

This is a single-phase two-wire electronic active Energy Limiting DC Meter, front board, wall mounting, with build-in Energy Limiter inside. It can set the daily maximum load limit.Besides Energy Limiting function, other common functions of this Energy Limiting DC Meter (eg: measuring accuracy) completely accord with relevant technical requirements of class 1 single phase active energy meter, stipulated in international standard IEC 62053-21. This Energy Limiting DC Meter can accurately and directly measure Direct Current (DC) from SOLAR, WIND or HYBRID POWER etc new DC power plants and electricity net. It can be installed to use indoor.

It can set the daily maximum load limit which limits energy consumed per day to prevent energy over-use.The build-in MCU handles all metering and control function, standalone.It can control/set by Hand Held Unit or Programm in computer.It has 6-digits LED display.It's equipped with a Real Time Clock and Load Relay, also has Warning LED Indicator to show the status of Load Relay.And it's also equipped with Overload Current Protection to make meter safer.

Operation Overview：

Each Energy Limiting Meter can set the starting time (eg: 6:00pm) everyday when the new allocation will begin. As soon as the designated time (6：00pm) is reached, the new allocation will take effect.Each Energy Limiting Meter can set daily limit of energy consumed. When the daily limit is reached, the meter will automatically cut off the load power, until the next day, a new kWh allocation is provided and take effect when the designated starting time (6:00pm) is reached. It runs in circle this way.

 

Setup Options：

The EnergyLimiting Meter can be set/controlled by

Hand Held Unit

Programm in computer.  

Hand HeldUnit Function

Hand Held Unit is use for setting the meter parameters, suchas Daily Limit, Alarm Energy, Time, Date, Power On ( Relay ) etc. It canconnect with Energy Limiting Meter directly by RJ11 port.

The basic functions as:

  15 keys & 16 x 2 LCD display

 No battery required (RJ11 powered)

 Build-in real time clock and calendar

  Set Starting Time

 Set Daily Usage Limited kWh ( Energy )

 Set Daily Usage Limited kW ( Active Power )

 Set Power on ( Load Relay restore )

l Set Daily Maximum Power Limit ( Overload )

   

It's an ideal application for SOLAR POWER, WIND POWER or HYBRID POWER etc new energy power plants.

It's suitable for where the energy is limited or rationed.

It's useful for Tenants, Rugged or Remote Villages, Isolated Islands.

This meter dispense with system software, telecommunication line, framework. It’s very easy to install and maintain.
