---

### **Cons**

1. **Higher Upfront Cost**

- The **modular approach** can be more expensive than a single, fixed-output power supply, especially for small-scale applications.

- Purchasing multiple modules to reach desired output levels may exceed the budget of cost-sensitive users.

2. **Complex Setup and Configuration**

- Requires **additional knowledge** to configure and integrate modules correctly, particularly for users unfamiliar with modular power systems.

- **Software setup** (e.g., configuring communication protocols) may require technical expertise.

3. **Limited Single-Channel Output (Per Module)**

- Each **1894-CG-DC module provides only one output channel**, meaning multiple modules are needed for **multi-channel applications**.

- If a user needs **multiple independent outputs**, they must purchase extra modules, increasing cost and complexity.

4. **No Built-in Display on All Models**
