NHK5-15AF Water Pump Control Box

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.
