2 Industrial Power Systems: High-reliability power distribution for industrial equipment

3 Power Generation Systems: Auxiliary power supply for power generation-related components

注意事项 PRECAUTIONS

1 Temperature: Do not operate the converter above 100°C (full load) to prevent damage; adhere to E-grade temperature limits (-10 to +100°C operating, -20 to +125°C storage)

2 Remote Sense: Connect remote sense leads (+S/-S) to respective output terminals; ensure total voltage drop across sense leads does not exceed 0.5V DC (0.25V per leg); protect sense leads from reversal, noise pickup, open circuit, or excessive resistance

3 Dynamic Load: If dynamic load exceeds 25% of rated current, contact Vicor Applications Engineering for review

4 Output Capacitance: Do not exceed output capacitance limits specified in the Maxi, Mini, Micro Design Guide

5 Soldering & Mounting: Follow recommended soldering methods and procedures from the design guide; select appropriate pin style for mounting (e.g., F/G pins for RoHS compliance)

6 Parallel Operation: For parallel use, ensure modules have same input voltage, output voltage, and power level; interface PR pins correctly (AC-coupled single-wire for up to3 modules, transformer-coupled for4+ modules); refer to design guide for detailed rules

7 Life Support: This product is not authorized for use in life support devices/systems without prior written approval from Vicor Corporation's CEO and General Counsel

8 Other: Under dynamic/light/no-load conditions, audible noise may occur; use fast-acting electronic circuit breaker if load may draw over rated current
