Voltage: Three phase 415V/50Hz
Rated current: 18.5A
Water sensors voltage: 10V-12V
Control Switch: Auto/Manual
This is an automatic control box which is designed for 415V/50Hz three phase submersible pumps.
The controller automatically controls the pump motor as well as providing comprehensive pump protection and phase failure protection. It works in either auto or manual way.
The box has metal casing, comes with a lock, 2 keys,Voltage guage, current metre and 6 water probes. It is compatible with all three phase pumps in the market that required auto switch pump on/off by water sensors.
Among these 6 probes, 3 are for monitoring the well's water level (up, mid and low) and the other 3 for monitoring the storage tank's water level. You can bypass either monitoring or both; to use a manual control box when needed. With the automatic box installed, the pump will turn on and off automatically according to the water levels of both the tank and the well. This is extremely important for using it in a well with limited water supply, as the pump only should be operating when it submerse in the water to get enough cooling and lubricating by the water going through it.
When turn control switch to “manual”. The control box will works bypass water sensors.
It can be installed at indoor or under cover.
