注意事项 PRECAUTIONS

1 Electrical safety: Do not exceed the rated load current (40A for5V200W output); use fast-acting electronic circuit breakers if dynamic loads may exceed rated current; avoid testing current limit or short circuit conditions as this may damage the module

2 Remote sense: Ensure total voltage drop on sense leads ≤0.5VDC (0.25V per leg); connect sense leads to respective output terminals; protect leads against reversal, noise, open circuit and excessive resistance

3 Dynamic load handling: Consult Vicor applications engineering if dynamic loads exceed25% of rated current; audible noise may occur under dynamic/light/no-load conditions; remote sense may need compensation circuitry for phase lag

4 Output capacitance: Do not exceed maximum output capacitance specified in Maxi/Mini/Micro Design Guide

5 Module enable/disable: Pull PC pin to ≤2.3V (relative to -IN) to disable; use open collector transistors, relays or optocouplers for control

6 Mechanical installation: Follow soldering guidelines (wave solder ≤260°C <5sec; hand solder ≤390°C <7sec); tighten mounting screws to5in.lbs (0.57N.m) torque

7 Storage: Keep in ESD-safe packaging (ANSI/ESD S20.20 compliant) at15-38°C with non-condensing humidity

8 Life support restriction: Not authorized for life support devices/systems without Vicor's prior written approval
