产品特点 FEATURES

1 Isolated, regulated DC-DC converter with wide input range (180-420 Vdc)

2 Nominal 12V output (SELV, Safety Extra Low Voltage), up to 400W continuous power (33.40A)

3 High efficiency: peak 92.9%, power density up to 826 W/in³

4 Reinforced isolation: 4242 Vdc between input and output

5 Zero Voltage Switching (ZVS) high-frequency topology for low noise and high efficiency

6 Supports array operation: up to 8 units in parallel (total 3200W), no power derating required

7 Comprehensive protections: overvoltage (OV), overcurrent (OC), undervoltage (UV), short circuit, and thermal protection

8 Compact through-hole ChiP package: dimensions 1.886" x 0.898" x 0.284" (47.91mm x22.8mm x7.21mm)

9 Fully operational current limit and sharing strategy for dissimilar line voltages in arrays

使用场景 APPLICATIONS

1 Industrial automation systems: power supply for control modules and sensors

2 Process control equipment: PLCs, data acquisition devices, and measurement instruments

3 Heavy machinery: construction, mining, and agricultural equipment's electronic subsystems

4 High-power applications: array configuration for 3200W systems (e.g., industrial power distribution)

5 Equipment requiring high isolation: systems where input and output circuits need strong electrical separation

注意事项 PRECAUTIONS

1 Input voltage must not exceed 460Vdc (absolute maximum); input slew rate limited to ±1V/µs

2 External output capacitor requirement: 1000-10000 µF with ESR ≤10mΩ to ensure control loop stability

3 Thermal management: maintain internal temperature within T grade (-40~125°C) or M grade (-55~125°C); over-temperature protection triggers at 125°C

4 Fault handling: output overvoltage protection (OVP) is latched—reset by power cycling input or disabling via EN pin; other faults (UVLO, OVLO, thermal) auto-recover after fault removal

5 Trim mode: TR pin state at power-up determines trim activation; active trim allows dynamic output voltage adjustment (7.2-13.2V)

6 Light load operation: when load <10% rated, output voltage may rise up to 2.62V due to light load boosting

7 Array operation: each unit needs separate input filter and output inductor (≥0.15µH) for decoupling; avoid sharing control pins (TR, EN, FT) between units if common mode chokes are used

8 Safety warning: not authorized for use in life support devices/systems without Vicor's prior written approval
