STE18-C is an STS Standard compliant, IC Card type, automatically connection or disconnection smart prepaid electricity meter
Our IC CARD meter also has remote automatic connection and disconnection function.However, the automatic power off of our electricity meter after normal operation mainly has the following functions:
1. Pull the brake to alarm and power off
The purpose of pulling the switch alarm is mainly to remind the user to buy electricity in time. For example, the power value of pulling the switch alarm is set to 10 degrees. When the electricity meter shows that the user has purchased the remaining power of 10 degrees, the relay of the household will automatically cut off to remind the user to buy electricity in time, and the household number will flash.Pulling alarm power value can be set through the computer networking system, can also be set by the IC card sales management system.
When there is a switch alarm power off, the user should go to the electricity selling center as soon as possible to buy electricity and input electricity meter, otherwise, after the user used up the switch alarm power off value, the electricity meter will be power off with zero balance.
2.Power off if the balance is zero
When the electricity meter shows that the electricity purchased by the user is 0 degrees, the relay of the household will automatically cut off, reminding the user that he must buy electricity. At this time, the household number flashes and the electricity consumption is displayed as -0000.0.At this time the user should as soon as possible to the sale of electricity center to buy electricity input meter.
3.Malignant load power
When the user uses the "malignant load" such as electric furnace, electric cup, electric heater and heating fast, the electricity meter can automatically recognize and power off, and automatically power on when such load is removed.(This function is suitable for apartment electricity management, must be customized)
4.Overload power
The electricity meter can set the load current of the user. When the user's electricity current exceeds the limit current, the electricity meter will automatically cut off the power supply circuit and automatically power on after 5 minutes. If the user's electricity current still exceeds the limit current, the electricity meter will be cut off again.
5, Timing control power
The electricity meter can control the time of the user's electricity consumption. The electricity meter can set the time of automatic power off and power on through the IC card selling system or the computer networking system, which is convenient for the management of the user's electricity consumption.
