Eaton IQ500 Series Multifunctional Power Mete

Event recording and alarm: Supports out of limit alarm detection (upper/lower limit monitoring), can monitor parameters such as voltage, current, active/reactive/apparent power, power factor, frequency, etc. Each monitoring object can generate out of limit SOE and return SOE, with a maximum of 32 out of limit alarm events recorded.

Input/output control: equipped with 4 passive switch inputs, capable of recording up to 32 switch SOE events; Supports 2-channel relay control output, enabling remote control and linkage protection.

3.2 Detailed explanation of time-sharing billing function

IQ500 has powerful time of use billing capabilities to meet the refined management needs under complex electricity pricing policies

Flexible configuration of rates and time periods: up to 4 rates, 12 time periods, 8 time period tables, 12 annual time zones, 90 public holidays can be set, and a weekly holiday time period table can be set.

Priority execution mechanism: Prioritize the execution of the time period table used for public holidays, followed by the time period table used for weekly holidays, and finally execute the time period table used for each time zone.

Dual switching mechanism: It has two sets of time zone tables, two sets of daily time period tables, and two sets of public holiday tables, and can automatically switch at set time points to adapt to seasonal or policy based electricity price adjustments.

3.3 Data Freeze Function

IQ500 supports multiple data freezing modes, providing a foundation for data analysis and auditing:

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

Instant Freeze: Immediately generate a freeze record after receiving the instant freeze command through communication.

Agreement freeze: When two sets of time zone tables switch, two sets of daily time period tables switch, or two sets of public holiday transitions occur, an agreement freeze is triggered once.

Freeze content: including total active power, total reactive power, and total active and reactive power data for each phase.

Storage capacity: The device can record 12 frozen records.
