Features Overflow Detection Function: The default wiring is water ingress detection. If you want the overflow detection function. What you need to have power on the alarm output terminals, the C terminal on the pump output and the C terminal on the alarm output n Intelligent Control: When the liquid level of the container is too low, the low liquid level alarm signal from the low liquid level sensor is triggered to trigger the controller to close the relay to start the water pump to add liquid level. When the liq Non Contact Induction Probe: Water level controller adopts non contact capacitance induction technology and special induction control chip design, the probe is durable, strong anti interference ability, sensitive induction, no contact with liquid, corros Wide Voltage Power Supply: Relay dry contact output, the controller can be applied to a variety of load. With Control diversification, water level controller can control the pump in manual or automatic mode. Easy to Install: The installation is simple and convenient. Water level controller can be screwed and installed, also can be installed on the electrical box track. Specification: Item Type: Automatic Water Level Controller Material: ABS Model: XKC C352 3P (fully automatic water level control and inlet or overflow detection) Input Voltage: AC100V to 260V, 50 or 60Hz Working Current: Working current ≤ 110mA, static current consumption ≤ 20mA Load power: Resistive loads up to 1.6KW (overload or for three phase loads require an AC contactor) Inductive loads below 1KW (overload or for three phase loads require additional AC contactors) Inductive loads are loads with inductive coils, such as motors, solenoids, solenoid valves, etc. Alarm Output: 800W (resistive load) normally open or normally closed output Output Mode: Normally open or normally closed output Input Signal: Inductive signal input Induction Head Interface Voltage: DC12V Working Temperature: -20 to 105℃ Size: Approx.115 x 90 x 40mm / 4.53 x 3.54 x 1.57in Package List: 1 x Automatic Water Level Controller 1 x Screwdriver Note: If you are not handy and not really very good with electrical stuff, please do not buy this controller, because it needs electrical engineering skills.
