ZY1501Pre-paid Energy Limiting Meter

This is a single-phase two-wire electronic active RS485On-line Pre-paid Energy Limiting Meter。

 This is a single-phase two-wire electronic active RS485On-line Pre-paid Energy Limiting Meter, front board, wall mounting, withbuild-in Energy Limiter inside.It can set the daily maximum load limit. It could be managedremote centralized by RS485 on-line.Besides Remote Centralized Management, Pre-paid and EnergyLimiting function, other common functions of this Meter (eg: measuringaccuracy) completely accord with relevant technical requirements of class 1single phase active energy meter, stipulated in international standard IEC62053-21.There are 50Hz or 60Hz 2 type meters available which canaccurately and directly measure 50Hz or 60Hz active energy consumption fromsingle phase AC electricity net.
It can be installed to use indoor.

Features:

It ismanaged remote centralizedby RS485 on-line

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 Register, LED Display (L)

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.

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.
