注意事项 PRECAUTIONS

1 Do not exceed the permissible load current during normal, abnormal, or test conditions; refer to the product specifications for detailed limits

2 Store the product in ESD-safe packaging when not installed, adhering to ANSI/ESD S20.20 standards to prevent electrostatic damage

3 Maintain storage temperature within the specified range (e.g., -55°C to +100°C for M grade, -40°C to +100°C for I grade, -20°C to +100°C for E grade) and relative humidity between 5% and 95% (non-condensing)

4 Avoid exposing the product to outdoor elements, dust, moisture, or uncontrolled factory environments to prevent performance degradation

5 When using the remote sense function, ensure the compensation voltage does not exceed 0.25V max to maintain output voltage stability

6 Do not connect the 'Out' pin on booster modules (as indicated in the mechanical drawing notes) to avoid device damage

7 For dynamic loads that fluctuate by more than 25% of the rated current, contact VICOR Applications Engineering to verify compatibility before use

8 Operate the converter strictly within its specified input voltage range to prevent overvoltage damage

9 Ensure proper heat dissipation: use the recommended thermal solutions (e.g., baseplate to sink thermal impedance of 0.07°C/Watt with VICOR PN 20266 cold plate) to maintain optimal operating temperature

10 Do not exceed the maximum output capacitance limits specified for different output voltages and power ratings to avoid instability

11 Use an active electronic circuit breaker instead of a fuse to protect the converter in applications requiring overcurrent protection

12 For applications involving output voltages below 5.2V or above 7.5V, consult the factory for specific current limiting information
