GSM Power Voltage Monitoring Alarm, Remote Control, Power Alert for 100-240V(US)

Features:

1. The GSM temperature monitoring alarm can reject calls from authorized numbers without making a call. Users can dial the device number by authorization number.

2. The device will automatically refuse to receive and immediately send short messages of the current status (temperature and voltage) to the caller.

3. Multiple applications (temperature, power state, solar panel, DC voltage).

4. Up to 10 authorized phone numbers, 5 can be used to answer calls or text messages, and 5 can be used for calls and text messages to generate alarms.

5. The built-in MCU has a measurement range of 0-36 VDC, eliminating the need for additional sensors and saving costs. It also supports remote reading of historical data via SMS.

6. Supports TCP and RTU over TCP protocol for cloud monitoring.

7. Use caller ID and password to identify and ignore unknown calls.

8. Can be programmed via SMS protected SMS command or APP.

9. Based on the GSM network, it is suitable for many applications.

10. Automatically restart the cycle by remote reset and restart via SMS.

Specifications:

The device operates on a standard 12VDC power supply, with support for 9~36VDC. In standby mode, it consumes 12V/20mA, and the maximum power consumption is 12V/150mA. It supports GSM frequencies of 850/900/1800/1900MHz and a 3V SIM card interface. The external antenna has an SMA interface with 50 ohms. It supports RTU Over TCP and TCP protocols. The built-in battery is 3.7V/900mAh. The operating humidity is relative humidity 95% (no condensation), and the size is approximately 70mm * 88mm * 30mm/2.8 * 3.5 * 1.2 inches.

Package List: 1 * GSM Alert 1 * Antenna 1 * Power Adapter 1 * Instruction Manual

Intelligent monitoring: The GSM power monitoring alarm is specially designed to remotely monitor the field power status through wireless communication. When the power supply voltage exceeds the set high threshold or low threshold, the SMS alert will be automatically sent to the preset mobile phone.

Remote monitoring: The power monitoring alarm can monitor the status of the field power supply wirelessly. It can be operated anywhere without distance limitations.

Authorization number: Users can dial the device number through the authorization number. The device will automatically reject the reception and immediately send the message to the caller about the current status (temperature and voltage). Users can also query the current status by SMS command. A device can support up to 10 authorized numbers.

Timing report: The device can set the daily fixed point and periodically report the current status message to the first user. It also supports Modbus RTU and Modbus TCP protocols to connect to the cloud, which can monitor the current status in real-time through the network.

Battery storage: There is a rechargeable backup battery inside, and the fully charged battery can be used continuously for 8 hours. It can be used to monitor industrial remote monitoring and control and automatic control systems such as power outage, machine room, temperature and humidity, street light, solar energy, refrigerator, generator, pressure, water level, crane wind speed, and meter.
