Features ABS material: made of high-quality ABS material, the liquid level regulator is wear-resistant and impact-resistant, ensuring long-term sensitive work. Work details: when the liquid level in the container is abnormal, the alarm signal is triggered by the liquid level sensor to control the water pump and adjust the water level. Wide application: relay dry knot output, which can be used for various load controls, e.g. for filling or emptying oil tanks. Sensitivity adjustable: you can adjust the sensitivity. Remove the plastic cover of the controller, turn the very small screw, reduce the sensitivity clockwise and increase the sensitivity counterclockwise. Easy installation: the installation is simple and convenient. The water level regulator can be installed by screw positioning or electric box rail. Specification: Item Type:Water Level Regulator Material: ABS Input voltage: AC100V-260V, 50 60Hz. Working current: working current less than or equal to 110mA, static current consumption less than or equal to 20mA Charging power: The ohmic load is less than 1.6 kW (overload or three-phase load requires additional AC contactor). Inductive load below 1 kW (overload or three-phase load requires additional AC contactor). Inductive load refers to the load with inductive coil, such as motor, electromagnet, solenoid valve, etc. Alarm output: 800W (resistive load), normally open, normally closed output Output mode: normally open, normally closed output Input signal: induction signal input Sensor head interface voltage: DC12V. Working temperature: -20 to 105 °C. Total size: approx. 115 x 90 x 40 mm / 4.53 x 3.54 x 1.57 inches.
