Technical Parameters:** - **Direct Start Control Cabinet:** - Motor Power: 0.37–15 kW - Control Voltage: 380V - Number of Pumps Controlled: 1–4 units - **Star-Delta Start Control Cabinet:** - Motor Power: 15–90 kW - Control Voltage: 380V - Number of Pumps Controlled: 1–5 units - **Auto-Decompression Start Control Cabinet:** - Motor Power: 15–160 kW - Control Voltage: 380V - Number of Pumps Controlled: 1–5 units - **Automatic Frequency Conversion Speed Control Cabinet:** - Motor Power: 0.18–250 kW - Control Voltage: 380V - Number of Pumps Controlled: 1–7 units - Pressure Control Accuracy: ±0.02 MPa --- **Main and Backup Pump Switching Modes:** - **Manual Selection:** The main and backup pumps are manually selected before startup. When the main pump fails, the backup pump automatically starts. - **Timed Automatic Switching / Manual Switching:** Suitable for regular rotation of main and backup pumps to ensure even usage. The switch time can be set at 4 or 8 hours. - **Alternate Automatic Switching / Manual Switching:** The main and backup pumps alternate automatically. If not needed, manual switching is also available. - **One Main, One Standby (Two Pumps):** Can operate in “I main, II standby” or “II main, I standby” mode. - **Two Main, One Standby (Three Pumps):** Operates in “I, II main, III standby,” “II, III main, I standby,” or “I, III main, II standby.” - **Three Main, One Standby (Four Pumps):** Supports four switching modes, including “I, II, III main, IV standby” and others. - **Two Main, Two Standby (Four Pumps):** Allows for flexible configuration based on flow rate or liquid level changes. - **Multi-Pump Control Modes:** All configurations include a manual function, allowing individual pump operation when needed. --- **Power Input Options:** - **Single Power Supply:** Direct connection of power lines. - **Dual Power Supply:** Two power sources are connected, with automatic switching between main and backup in case of failure. --- **Control Types:** - **Level Control (Unlabeled):** Uses a high-performance float switch (Italian technology) for automatic liquid level control. Other controllers like OMRON can also be used. - **Pressure Control (P Type):** Uses an external pressure gauge or controller for pressure-based pump control, commonly used in water supply and fire booster systems. - **Temperature Control (T Type):** Uses an external temperature controller for temperature regulation in heating and cooling systems. - **Time Control (S Type):** Equipped with a timer for scheduled pump operation, ideal for regular or intermittent use. - **Air Conditioning Pump Control (K Type):** Designed for air conditioning systems, it ensures safe operation by linking pump activation with refrigeration unit start-up. - **Firefighting Control (X Type):** Complies with national fire codes, offering panel manual start, pressure switch activation, and DC24V control from the fire center. - **Submersible Sewage Pump Control (L Type):** Includes additional protections like leakage, phase loss, and motor overheat monitoring, specifically for submersible pumps. --- **Starting Methods:** - **Direct Start (for motors ≤ 15 kW):** Simple and efficient, but not recommended for frequent use. - **Y-Δ Start (for 15–45 kW):** Reduces starting current, suitable for most applications except submersible pumps. - **Auto-Coupling Start (for motors > 11 kW):** Provides higher starting torque, ideal for infrequent starts. This control cabinet is a versatile and reliable solution for modern pump systems, offering flexibility, safety, and efficiency across a wide range of applications.
