使用场景 APPLICATIONS

1 Industrial control systems: Power supply for programmable logic controllers (PLCs), sensors, and actuators in manufacturing lines

2 Process automation: Distributed power modules for equipment used in chemical processing, food production, and other industrial processes

3 Automatic Test Equipment (ATE): Reliable power conversion for precision testing instruments and measurement systems

4 Commercial communication devices: Power solutions for routers, switches, and other network infrastructure components

5 Distributed power systems: Modular power units in commercial electronic equipment to enhance energy efficiency and fault tolerance

注意事项 PRECAUTIONS

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

2 For dynamic loading exceeding 25% of the rated current, consult Vicor Applications Engineering before use

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

4 Remote sense leads must be protected against reversal, noise pickup, open circuit, or excessive resistance; compensation circuitry may be required to offset phase lag

5 Use fast-acting electronic circuit breakers to protect the converter from overcurrent beyond the rated limit

6 Do not exceed the maximum output capacitance specified in the Maxi, Mini, Micro Design Guide

7 When trimming output voltage down: Available output power reduces proportionally to the voltage reduction; do not exceed the maximum rated current

8 When trimming output voltage up: Reduce the maximum output current proportionally to the voltage increase; do not trim above +10% of the nominal voltage to avoid activating overvoltage protection

9 Parallel operation requires modules of the same input voltage, output voltage, and power level; follow PR pin interface guidelines (AC-coupled for up to 3 modules, transformer-coupled for more)

10 Store the module in ESD-safe packaging at 15–38°C with no condensing humidity

11 Soldering methods must comply with the instructions in Vicor's Maxi, Mini, Micro Design Guide

12 This product is not authorized for use in life support devices or systems without prior written approval from Vicor's Chief Executive Officer and General Counsel
