SEMI AUTOMATIC WATER PUMP CONTROLLER
সেমি অটোমেটিক ওয়াটার লেভেল কন্ট্রোলার
Model Name: WLC02
Price: Rs 1,499/-

Suitable for the normal pumps that are used to lift water from reservoir to overhead tank

Silent Features:
1. This model is suitable for the normal pump which is used to lift water from reservoir to overhead tank and who wants to switch ON the pump manually and switch OFF it automatically. When user want to switch ON the pump then it is necessary to press START button (green colour). The pump will be switched OFF automatically when the overhead tank is filled with water or reservoir tank becomes empty. Of course, user can switch OFF the pump anytime by pressing STOP button (red colour) as needed.

2. The circuit does not consume any electrical power when the pump is switched OFF. The internal circuit consumes very small current (100mA) only when the pump is running.

3. If the internal circuit do not function properly then user can switch ON or OFF the pump easily by using manual switch. To switch ON the pump it is necessary to keep the switch in MANUAL position and to switch OFF the pump place it in OFF position. For normal operation it is necessary to keep the switch in SEMI AUTO position.

4. This model is suitable for upto 2 H.P. pump. The internal circuit has a electromagnetic relay which can permit maximum 30A current. The semi auto-manual switch is also allows maximum 15A current.

5. Internal circuit has a good quality Switch Mode Power Supply (12V, 1A).

6. Light weight, Wall mounted, PVC cabinet (white colour), Good quality and high rated connectors for giving inputs like 230V A.C. voltage & sensors signals and taking output voltage for motor.


7. Only four nos. contact sensors needed-two sensors for reservoir tank and another two sensors for overhead tank. We have recommended carbon type contact sensors because it is free from oxidation and thus require no maintenance. Any user can also use steel contact sensor or magnetic float switch. 


8. Four LED indicators for Power, Motor ON, Reservoir water and reservoir empty.


9. One year warranty. No compromise against quality. This is a quality product, Long life time and low price.
