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.
Specification:
| Type | Dimension Range (Height × Width × Depth, unit: mm) | Description |
| Common Sizes | Small: 1200×600×400 | Suitable for simple control systems with few components, such as
small water pump or fan control. |
| Medium: 2200×800×600, 2200×800×800 | Ideal for medium-sized systems, capable of accommodating inverters,
PLCs, and more auxiliary components (e.g., sensor interfaces,
relays). |
| Large: 2200×1600×800 | Used in complex industrial scenarios, supporting linkage control of
multiple devices with sufficient internal expansion space. |
| Height: 1800-2200 | Can be adjusted according to installation space (e.g., machine room
size, wall-mounted/floor-standing requirements) and the number of
components. |
| Width: 600, 800, 1000 |
| Depth: 400-800 |
| Examples of Special Specifications | 600×1200×350, 1500×700×400, 1700×700×400 | Designed for specific scenarios (e.g., installation in compact
spaces, matching with dedicated equipment). |
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).
