产品特点 FEATURES

1 Isolated, regulated DC-DC converter with wide input range (9-50VDC) and nominal 3.3V Safety Extra Low Voltage (SELV) output

2 High performance metrics: Up to80W continuous power,24.30A output current; peak efficiency of87.7% and power density of206W/in³

3 Strong isolation:2250VDC isolation between input and output/case,707VDC between output and case; insulation resistance≥10MΩ at500VDC for1 minute

4 Advanced topology: Zero Voltage Switching (ZVS) high-frequency switching enables low-profile, high-density filtering

5 Array operation support: Can be paralleled up to8 units for total640W power; no power derating needed; allows dissimilar line voltages across the array

6 Comprehensive protection: Overvoltage (OV), overcurrent (OC), undervoltage (UV), short circuit, and thermal shutdown protections; fully operational current limit (100-136% of rated current at nominal trim)

7 Temperature resilience: Available in three grades—C(-20~125°C), T(-40~125°C), M(-55~125°C) for storage and operation

8 Long reliability: MTBF of3.39MHrs (MIL-HDBK-217 FN2) or5.68MHrs (Telcordia Issue2)

9 Compliance certifications: cURus(UL60950-1), cTÜVus(EN62368-1), UKCA, CE marked(Low Voltage, RoHS)

使用场景 APPLICATIONS

1 Industrial applications: Powering control systems, sensors, actuators in manufacturing lines with variable input voltages

2 Process control: Supplying stable power to PLCs, DCS modules, measurement instruments in chemical/petroleum/food processing plants

3 Transportation/Heavy Equipment: On-board electronics for trucks, buses, excavators, cranes with fluctuating input power

4 High-power systems: Array operation (up to8 units) for640W industrial power supplies or large-scale process control setups

5 Point-of-Load integration: Single unit connected to non-isolated PoL regulators for microprocessors/FPGAs in embedded systems

注意事项 PRECAUTIONS

1 Input requirements: Use low-noise power source; add input capacitance if source impedance is excessive; select fuse with current rating>max DCM current and voltage>max input voltage

2 Output capacitance: Must use1000-10000µF capacitor with≤10mΩ ESR; increase to4700-10000µF (static trim) or7000-10000µF (dynamic trim) when load<20%

3 Thermal management: Cool top/bottom surfaces and leads for full power; ensure case bottom temp≤case top temp (OTP sensor on top); use Vicor PowerBench for thermal analysis

4 Array operation: Each unit needs separate input filter; add output inductor per unit before bussing outputs; isolate control pins if using common-mode chokes

5 Fault handling: OVP is latched (clear via EN disable or input power removal); non-latched faults recover automatically after wait time

6 Soft-start: Output current limited until VOUT reaches1.7V; max start-up current below this threshold is2.42A

7 Light-load boosting: Output voltage may rise up to1.01V when load<20% rated current

8 Safety warning: Not authorized for life support devices without Vicor's prior written approval

9 Compliance: Follow application notes (AN:023/030/036/301) for proper usage
