Detail Information
Introduction
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.
Application
This Energy Limiting Meter is ideal in SOLAR, WIND or HYBRID POWER etc some new power plants.
It’s suitable for applications where the amount of energy is limited or rationed per day.
It’s useful for tenants, rugged or remote villages, isolated islands.
It also can be equipped for requiring subsidized billing.
General Function
The simplest Energy Limiting DC Meter is a unique new energy meter that limits energy consumed per day to prevent energy over use.
The built-in MCU handles all metering and control function.
This Energy Limiting Meter is equipped with a real time clock and a load relay.
This Energy Limiting Meter also has warning LED indicator to show the status of load relay.
And it is equipped with Overload Current Protection to make it more safer.
Operation Overview
Each Energy Limiting DC 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 DC 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.

Overload Protection
(1). Overload Protection :
Usually the maximum current for the Energy Limiting Meter is 10A only.
When the current reach 20A, the meter will turn off in 30 seconds;
When the current reach 30A, the meter will turn off in 15 seconds;
When the current reach 40A, the meter will turn off in 5 seconds.
If the meter overload, LED is blinking "P_OV".
(2). Restore:
The Energy Limiting Meter will restore after 30 seconds for over-load off. If over-load is still there, it
will perform the over-load protection process.
After 10 attempts, it will stop the restore operation.
At this time, the users have to restore it manually.
Setup Options
