产品特点 FEATURES

1 Isolated fixed-ratio DC-DC bus converter (model BCM48BT480T300A00) with transformation ratio K=1 (VOUT = VIN)

2 Input voltage range: 38V DC to 55V DC; output power: 300W (peak 375W for ≤10ms)

3 High efficiency: Up to 96.2% (at 48V input, full load, 25°C case temp) reduces system power consumption

4 High power density: >1022W/in³, cutting power system footprint by over 40%

5 Built-in multi-layer protection: Undervoltage lockout, overvoltage lockout, overcurrent protection, short circuit protection, overtemperature protection

6 Integrated control and monitoring: Supports enable/disable (PC pin) and internal temperature monitoring (TM pin)

7 Scalable design: Can be paralleled to create multi-kW power arrays for high-power applications

8 Through-hole package: Easy to mount on PCBs with stable mechanical performance

9 Safety certifications: Complies with cURus, cTÜVus, UKCA standards; CE marked for Low Voltage Directive and RoHS Recast Directive

使用场景 APPLICATIONS

1 High-end computing systems: Ideal for powering servers, workstations, and data center equipment that demand high efficiency and compact size

2 Automated test equipment: Provides reliable power for precision testing instruments in industrial labs and manufacturing lines

3 High-density power supplies: Used in space-constrained applications like telecom base stations, industrial control cabinets, and compact power systems

4 Communications systems: Supports power distribution in routers, switches, and telecom infrastructure to ensure stable operation

5 Multi-kW power arrays: Paralleled modules are suitable for large-scale power systems such as data centers and industrial automation setups

注意事项 PRECAUTIONS

1 Absolute maximum ratings: Do not exceed input voltage (60V max), isolation voltage (2250V), or other stress ratings as it may cause permanent device damage

2 Thermal management: Keep the case temperature below 100°C to maintain internal junctions within 125°C; use proper heat sinking for extended full-load operation

3 Input impedance: Ensure input source impedance is low (DC to ~5MHz); if interconnect inductance >100nH, add an RC damper (1µF in series with 0.3Ω) or electrolytic capacitor

4 Fuse installation: Install input line fuses (≤10A Littlefuse Nano2 recommended) for system-level thermal protection

5 Reverse power: Avoid continuous reverse power transfer (not qualified); transient reverse is allowed but not for long-term use

6 Parallel arrays: For effective current sharing, use symmetric PCB layouts, common copper planes, and identical filters for all modules

7 Safety warning: Not suitable for life support devices/systems without Vicor's prior written approval

8 Mounting guidelines: Follow recommended through-hole land patterns and heat sink push-pin locations (including keep-out zones and spacing requirements)
