2~31Harmonic analysis;

Electricity metering function

Combined active total electricity measurement, combined active electricity measurement for each rate;

Positive and negative total active electricity measurement, positive and negative active electricity measurement for each rate;

Combined reactive power1Total electricity consumption, combined reactive power at various rates1Electricity measurement;

Combined reactive power2Total electricity consumption, combined reactive power at various rates2Electricity measurement;

Four quadrant reactive power total electricity measurement, four quadrant electricity measurement for each rate;

The total amount is measured in electricity, and each rate is measured in electricity;

Time of use billing

Maximum adjustable4 Individual rates12 Time period8 Daily Time Schedule12 Time zone of one year90 A public holiday;

It has two sets of time zone tables, two sets of daily time zone tables, two sets of rate electricity prices, two sets of tiers, and can be switched at set time points;

Prepaid fees

Remote prepaid function, pay first, then use electricity;

The instrument can be set at most4Individual rate electricity price and4Tiered electricity pricing;

Overdraft function, electricity bill amount is0Allow users to overdraw certain fees;

Hoarding function, the remaining amount in the table cannot exceed the set maximum stored value;

Settlement function

The instrument can automatically save the current power and demand data according to the pre-set settlement time;

The instrument can be saved12 Monthly settlement of electricity data and updates3Monthly settlement of maximum demand data;

The settlement date parameters can be set monthly1~28Set arbitrarily within the day;

The instrument automatically settles the tiered electricity based on the set settlement cycle;

Freeze function

Periodic timed freezing function: Based on the set freezing time, it can achieve timed freezing of electricity data on a monthly, daily, or hourly basis;

Instant freezing function: Immediately freeze the current battery level after receiving the instant freezing command through communication;

Agreed freeze function: When two sets of time zone tables switch, two sets of daily time zone tables switch, or when there is a transition to tiered electricity prices, a agreed freeze is triggered once;

Event recording function

Extreme value data recording: Record the maximum and minimum values of voltage, current, and occurrence time for the current day, the previous day, and history;

Zeroing event record: Zeroing battery level, zeroing demand, and the instrument records the most recent events separately3 Secondary reset event;

School time event record: Instrument records the most recent10 Secondary school incident;

Electricity purchase event record: Recently recorded by instruments10 Secondary power purchase event;

Relay closing event record: The instrument records the most recent relay output10 Record of the second opening and closing of the switch;

Switching event recording: The instrument can record digital switching inputsSOEevent;
