注意事项 PRECAUTIONS

1 Do not exceed the rated load current under normal, abnormal, or test conditions

2 For dynamic loading exceeding25% of rated current, contact Vicor Applications Engineering before use

3 Audible noise may occur under dynamic load, light load, or no-load conditions

4 If using remote sense, add compensation circuitry to offset phase lag from external leads; protect sense leads against reversal, noise, open circuit, or excessive resistance

5 Use a fast-acting electronic circuit breaker for applications that may draw over-rated current

6 Do not exceed the maximum output capacitance specified in the Maxi/Mini/Micro Design Guide (page16)

7 Output voltage trimming guidelines:

8 Trim down: Do not go below10% of nominal; trimming below90% may require a minimum10% load

9 Trim up: Do not exceed10% above nominal (to avoid activating overvoltage protection); reduce max output current proportionally with voltage increase

10 Parallel operation: Use AC-coupled interface for up to3 modules, transformer-coupled interface for4+ modules (refer to design guide for details)

11 Storage: Keep in ESD-safe packaging at15-38°C with non-condensing humidity

12 Follow Vicor's soldering methods (from design guide) for correct installation

13 This module is not authorized for use in critical life support devices without Vicor's written approval
