Feature: 1. RELAY CONTROL: Water level controller switch is controlled according to the detection of water level of the pool (water tower), and the high current relay is used to realize the control 2. VARIOUS FEATURES: Small size, easy wiring, low power consumption, large switching capacity, strong interference prevention, and high functional stability 3. AUTOMATIC PUMPING: Can stably realize the automatic start of the water pump to pump water when the pool (water tower) is short of water, and automatically stop the pump when the pump is full 4. STRONG COMPATIBILITY: This water level controller module is highly compatible and can be used with a variety of liquid level sensors 5. BASIC SPECIFICATIONS: Water level controller switch is made of PCB material, the control output is 0~10A, the installation is simple and convenient Specification: Item Type: Water Level Controller Module Material: PCB Power Supply Voltage: 9V-12V (Both AC and DC) Control Output: Current 0~10A Control Power: 0~1KW 220V (Can control 2KW). Package List: 1 x Water Level Controller Module Note: 1. Can be directly sensed with household wires. Strip the end of the wire by more than 5cm, so that can be directly sensed by the bare wire that can touch the water.2. There is no need to purchase additional probes, and the probes can be replaced by household wires. (The so called probe is a wire that is buckled with a plastic mesh shell, and can be directly sensed with a household wire. Strip the wire end about 3cm to make it a bare wire for direct induction. Where suggested contacts stainless steel would be better!)
