- Unmanned Pump Control, Choose 3S
Shanghai 3S Global Company Limited
Application Field: Outdoor main pumps at ports and terminals, water supply for coastal chemical plants. The Stainless Steel Automatic Single Water Pump Controller supports RS485 industrial protocol integration.
Multi-Mode Intelligent Control Logic
Automatic Operation: Connect to liquid level, pressure and other sensors for intelligent start-stop.
Timed Control: Supports operation by time periods to meet irrigation/drainage needs.
Manual Control: Facilitates on-site commissioning or emergency intervention operations.
Remote Control (Optional): Connect to the central control system via RS485 interface to realize remote start-stop and status monitoring, a key function of the IP55 three phase pump control panel.

After power-on, it enters the initial mode. Press the "self-learning" button for 5 seconds to enter the self-learning state.
You can set the operation mode, protection parameters, timed start-stop logic, etc., through the menu.
The LCD screen of the IP55 three phase pump control panel can display real-time operating status, voltage and current, water tower liquid level, fault codes and other information.
Q1: What is the maximum load current supported by the IP55 three phase pump control panel?
A1: Different models have different maximum currents corresponding to their rated powers. Please refer to the power range (4.0kW to 30kW) in the technical specification table to ensure the model selection meets the current requirements of the on-site pump.
