Remarks

1. The "Maximum Output Capacity" only represents instantaneous capacity and is not intended for long-term continuous operation.

2. Can be custom-made to provide an EPO function, allowing external control for operation/shutdown, and it can also save standby power consumption.

3. A single module is suitable for single-phase AC, and multiple modules in parallel can adapt to three-phase four-wire systems. When the power supply is balanced, the effective value of the N-line current is less than 10% or a maximum of 5A.

4. Modules can work in series or parallel. For series operation, it is recommended not to exceed 2 units, and there is no limit to parallel operation. However, the length of the lines from the power source to the load must be as consistent as possible or use busbars; otherwise, it will affect the current equalization effect. CAN allows parallel operation and provides monitoring and communication functions.

5. When the operating ambient temperature exceeds 40°C, a 10% derating is applied from 40 to 45°C. Shutdown occurs when the internal temperature test point exceeds 80°C.

6. The default airflow direction for the module is front-to-back. For modules with a DC voltage greater than 48V, it can be adjusted to back-to-front as needed.

7. Some products are non-standardized and may be upgraded or adapted based on customer needs or system changes. Therefore, the product specifications are for reference only, and actual communication will prevail.

8. For any requirements not mentioned above, please call to obtain relevant information or specifications.
