Беспроводной монитор питания

This device is wireless energy meter with frequency 433.92MHz. The transmittingdistance is up to 30 meters. The receiver with LCD screen can display all relatedelectrical data from 4 transmitters simultaneously. Four different time periodswith different tariffs can be set. And it has a alarm function for maximum totalused energy or maximum accrued energy cost.1. Display of low battery energy alarm.2. Display of temperature and humidity.3. Display of total used energy and accrued energy cost from four transmitters.4. Display of the COST, kWh, W, VA, V, A, PF, Hz of every transmitter separately.5. It has calendar function, which can display year, month, day, time, and week.6. Four different time periods with different tariffs can be set.7.This device will enter into energy saving mode once there is no operation within one minute.8. Press the button “MENU” to refresh all data from transmitters in compulsion on display mode. Normally, the receiver displays the refreshed data automatically every seven seconds.9. The maximum total used energy or accrued energy cost can be set. If it exceeds your set value, the symbol “ ” will blink continually.Bitmap10.The data of used energy cost and accrued energy can be saved even if the transmitter is power off and the battery is out of energy. So, you do not worry about the data loss.11. Reset the data from each transmitter or all transmitters.Technical data:Receiver:Transmitter:1. Frequency: 433.92 MHz1. Rating voltage: 230V AC, 50/60Hz2.
