Product Advantages

1. Enhanced Safety Features ?
? ?- Overload Protection: Automatically detects and protects the pump from running under excessive load conditions. ?
? ?- Dry Run Protection: Prevents damage caused by the pump running without water, safeguarding the system. ?
? ?- Phase Failure Protection: Ensures that the system remains operational even in the event of a phase failure, avoiding damage to the motor.

2. Reliable Performance with Multi-Mode Control ?
? ?- Water Level Mode: Controls the pump operation based on water level sensors, optimizing performance for water supply systems. ?
? ?- Pressure Mode: Monitors and adjusts pump operation based on pressure, ensuring a stable and constant pressure level in the system.

3. Convenient Control and Monitoring ?
? ?- Multiple Display Indicators: Displays real-time information, including voltage, current, water level, pressure, operational mode, and fault status, ensuring transparency of the system’s performance. ?
? ?- Manual and Automatic Modes: Provides the flexibility to operate the pump manually or automatically, catering to different user preferences and operational requirements.

Product Features

1. Time Control Functions ?
? ?- Cyclic Start Time: Allows the system to start and stop periodically, reducing wear on the pump and ensuring optimized performance. ?
? ?- Timed Shutdown: Offers the ability to set a specific time to shut down the pump, preventing unnecessary operation and saving energy. ?
? ?- Delay Restart: Prevents immediate restarts, giving the system time to stabilize after a power failure or shutdown, which reduces the risk of mechanical damage.

2. Comprehensive Protection System ??
? ?- Undervoltage and Overvoltage Protection: The box monitors voltage levels, ensuring the pump operates within safe electrical limits. ?
? ?- Phase Failure Protection: In case of phase failure, the system shuts down to prevent damage to the motor or other connected components.

3. Wide Compatibility and Integration ?
? ?- Floating Ball: Used to detect water levels for automatic pump control. ?
? ?- Pressure Switch: Ensures the pump operates based on pre-set pressure parameters. ?
? ?- Electric Contact Pressure Gauge: Provides real-time pressure readings for accurate system monitoring and control.
