Solar Powered Version: - IP68 waterproof: Not afraid of exposure to the sun and rain thanks to glue process for sealing - Monocrystalline solar panel supports weak light: A 10-year warranty. It has better charging performance and higher charging efficiency even on cloudy days - 18650 lithium battery: With a large capacity and a long battery life. On cloudy days, it can be used normally for more than a month - Solar powered version with stainless steel screws and a stainless steel bracket Features: - Wireless water level controller - High performance and more stability - Maximum working range (optional): 1000 meters, 2000 meters and 5000 meters - Water level display, power-down memory and multiple protections - AC 60-450V ultra-wide voltage input range: Switching power supply isolation. High efficiency and energy saving. Compatible with 110V/220V/380V input - SPI RF communication technology: high-gain antenna, 10-second signal monitoring, strong penetration, strong anti-interference and more stable - LED visual operation interface: manual start, water level visualization, fault visualization and operation visualization. These intelligent designs make it easy to operate - Two installation methods: The water level controller can be fixed by screws and guide rails. It is more flexible to install and use - Induction line: Made of 304 stainless steel, probes are resistant to 105C high temperature and corrosion. They can adapt to a wide range of water quality. By default, the total length of the line is 2m/6.6ft, and the sensing depth is 1.2m/3.9ft - Automatic and manual control modes: 1. Automatic mode: Take water supply mode as an example. When the water level reaches the lower limit, it will automatically turn on. When the water level reaches the upper limit, it will stop. 2. Manual mode: When the device is stopped, users can press the start button to start the device. When there is full of water, it will automatically shut down - Settable water level: Users can adjust the water level for starting and stopping by modifying the parameters based on actual usage scenarios - Water shortage protection: Your water pump is started. If the water level does not change within the set time, the controller will automatically power off and display Er.1 (water shortage protection). By default, the alarm will be cleared after 60 minutes - Timeout protection: Your water pump is started. When the water level does not rise to the set upper limit within the set time, the controller will automatically power off and display Er.7 (timeout protection). When the controller cannot control automatically, a timer can be used for semi-automatic control - Communication protection: Within 5 minutes when no transmitter signal is received, the receiver will display Er.8 (communication protection alarm). When communication is restored, the device will automatically disarm the alarm - Supports water supply and drainage modes: The device supports water supply mode by default. When the water level reaches the lower limit, the device will start the water supply mode. When the water level reaches the upper limit, the equipment will stop supplying water. Users can adjust the device to the drainage mode by modifying the parameters, that is, when the water level reaches the upper limit, the device will start the drainage mode. When the water level reaches the lower limit, the device will stop draining - With input and output wiring marking and 30A high-current terminal blocks - Application scenarios: Domestic water towers, electrical cabinets in machine rooms, factory pools, municipal water supply, agricultural irrigation and aquaculture Product Parameters: Receiver Controller: - Input voltage: AC60~450V/50HZ - Rated load: water pump/motor 3000W - Standby power consumption: less than 0.55W - Size: 96mm x 80mm x 48mm/3.8" x 3.1" x 1.9" Solar Powered Transmitter: - Operating temperature: -20C to 65C - IP rating: IP68 35C - Minimum transmission distance: 400 meters - Maximum transmission distance (optional): 1000 meters, 2000 meters and 5000 meters - Size: 100mm x 68mm x 48mm/3.9" x 2.7" x 1.9" General Parameters: - Net weight (solar powered version): 0.6kg Package Included: - 1 x Controller - 1 x Transmitter for water level monitoring - 1 x Controller antenna - 1 x Set of fixing accessories - 1 x User manual Packaging Details: - G.W.: 0.65kg Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
