使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs (Programmable Logic Controllers), motor drives, and control circuits in manufacturing lines

2 Process control equipment: Providing isolated 12V power to sensors, transmitters, and data acquisition modules in chemical, pharmaceutical, or food processing plants

3 Transportation and heavy equipment: Power distribution in trucks, construction machinery, and agricultural vehicles (e.g., battery-powered systems requiring wide input range)

4 Industrial machinery: Isolated power supply for auxiliary components like lighting, displays, and communication modules in heavy-duty machines

5 Battery-powered devices: Suitable for equipment using multi-cell battery packs (e.g.,48V/72V industrial batteries) that require stable 12V output

注意事项 PRECAUTIONS

1 Electrical operation: Do not exceed absolute maximum input voltage (175Vdc) or output voltage trim range (7.2-13.2V) to prevent damage or overvoltage protection (OVP) triggering

2 Thermal management: Ensure internal temperature (TINT) does not exceed 125°C (T-grade). Use proper cooling (top/bottom surface heat sinks or lead thermal conduction) as per Vicor's thermal design guidelines

3 External components: Install minimum external output capacitor (1000-20000µF with ESR ≤10mΩ) for control loop stability; add recommended input filter (1µH inductor +2µF ceramic caps) to attenuate noise

4 Signal pin usage: For FT pin, use a series resistor to limit current (max4mA) to avoid module damage. Unused TR/EN/FT pins can be left floating (internal pull-ups are present)

5 Fault handling: Output overvoltage protection (OVP) is latched—clear by disabling the EN pin or reducing input voltage below VIN-INIT (6V). UVLO/OVLO faults auto-recover once input voltage returns to normal range

6 Light load operation: When load is less than10% of rated current, output voltage may rise up to3.09V (light load boosting); verify compatibility with downstream circuits

7 Safety warning: This product is not authorized for use in life support devices/systems without Vicor's explicit written approval
