Industrial Automation PLC Control Cabinet Inverter Ventilation System
Product Describe:
1. Precise speed regulation and energy saving: The frequency converter achieves stepless speed regulation of the motor through frequency adjustment, avoiding energy waste caused by "big horses pulling small cars" (especially suitable for variable load scenarios such as fans and water pumps, with an energy saving rate of up to 20% -50%).
2. Automation and Intelligence: PLC can write complex logic programs to achieve automatic start stop, dynamic adjustment based on sensor data (such as automatic adjustment of pump speed according to pipeline pressure in constant pressure water supply systems), automatic fault alarm and other functions, reducing manual intervention.
3. Safety and reliability: Integrated with multiple protection functions, it can prevent motor overload, short circuit, and overvoltage. At the same time, the structural design of the control cabinet (such as heat dissipation and dust prevention) ensures stable operation of the equipment in industrial environments.

Material:
Aluminum alloy, stainless steel, carbon steel
Suggestion:
1. Match core parameters
Ensure inverter power is 10-20% higher than the motor’s, with 15-20% extra capacity for multi-device setups.
Choose basic PLCs for simple control (e.g., single pump) or advanced models with analog/communication modules for complex logic (e.g., remote monitoring).
2. Fit structure and environment
Opt for floor-mounted cabinets (≥1800mm height) for large systems, or wall-mounted (≤1200mm) for small setups, checking weight capacity.
Use IP54+ enclosures for dusty/damp areas; add explosion-proof features for hazardous zones.
3. Add functional extras
Include a 7-10 inch touchscreen for parameter adjustments; integrate 4G/Ethernet for remote access if needed.
Ensure overload/short-circuit protection; add temperature sensors for high-heat environments.
4. Optimize cooling and wiring
Use forced air cooling for inverters over 5.5kW; separate power and signal cables to avoid interference.
5. Balance cost and lead time
Prioritize standard components to cut costs. Allow 7-15 days for simple customizations, 30-45 days for complex ones (e.g., explosion-proof designs).
