V300B48C150BG 概要
An isolated DC-DC converter module is a packaged power supply subsystem that combines an isolation transformer, control circuitry, and output rectification in a single chassis-mountable brick or module format. Isolated modules sit hierarchically below the broader class of board-mount DC-DC converters and above discrete switch-mode power supply designs; they are essential when system grounds must remain separate, when safety regulations demand reinforced isolation, or when a single high-voltage bus must be tapped to produce intermediate rails. Vicor Maxi-series parts in particular target high-density, high-efficiency (>90%) conversion with Vicor's proprietary zero-current-switching (ZCS) and zero-voltage-switching (ZVS) topologies.
Key features of the V300B48C150BG include ±0.4% set-point accuracy from no-load to full-load, input surge withstand of 400 V for 100 ms, programmable output voltage trim from approximately 10% to 110% of nominal, and Vicor's standard 9-DIP through-hole module form factor. Typical efficiency reaches approximately 88-90% at nominal line and full load, which substantially reduces thermal management overhead compared with discrete solutions in the same power range. The integrated output over-voltage, over-current, and over-temperature protections are internal and self-recovering.
Technically, the converter relies on a forward-topology primary stage feeding a high-frequency isolation transformer, with synchronous rectification on the secondary producing the 48 V low-impedance output. Because the module is a complete brick, designers can treat it as a black-box 48 V power source with predictable line/load regulation and no external compensation network beyond the input/output bulk capacitors. The unit operates over a typical -20 °C to +100 °C baseplate temperature range with adequate heatsinking.
Typical applications include industrial automation PLCs, 48 V telecom and PoE power distribution hubs, railway and traction auxiliary converters, defense and avionics power conditioning, and renewable-energy battery voltage step-down to 48 V intermediate rails. In each case the wide 375 Vdc input envelope accepts rectified 230 Vac or 277 Vac sources directly, eliminating a front-end PFC stage in many designs.
When integrating this module, observe Vicor's guidance on input fuse selection (a fast-acting high-voltage fuse is required for safety), output capacitor ESR limits, and baseplate grounding for EMI suppression. Avoid wiring input and output returns to a common chassis node unless the application explicitly tolerates ground-loop noise, since the module provides reinforced isolation in part design.
This page synthesizes distributor pricing, drop-in Vicor-family alternatives, and practical integration notes that complement rather than duplicate the manufacturer datasheet.

Telecom 48 V Power Distribution Hub
Why V300B48C150BG fits: Telecom central offices and remote radio heads run on standardized -48 V or +48 V distribution buses; the V300B48C150BG's 48 V output at 3.13 A draws cleanly from a 300 V rectified telecom front-end and re-presents the rail at telecom-grade isolation. Reinforced isolation between input and output is essential for the floating-bus architectures that PoE and small-cell base stations require. How it is used and performance: Connected between the high-voltage intermediate bus and the 48 V distribution frame, it sustains ±0.4% regulation across load transients, supporting switched-mode baseband and RF amplifier rails without adding common-mode noise.
おすすめ
Railway and Traction Auxiliary Power
Why V300B48C150BG fits: Rolling-stock auxiliary converters operate from 600 Vdc or 750 Vdc traction buses; the V300B48C150BG's 375 Vdc maximum input cannot accept these voltages directly but pairs naturally with a Vicor pre-stage or with battery/catenary-fed 300 V intermediate rails in light-rail and metro subsystems that step down to 48 V for passenger-information displays, door controls, and on-board communications. How it is used and performance: Delivered inside a fan-cooled tray or heatsink assembly, it provides the vibration-resistant, isolated 48 V supply demanded by EN 50155 railway standards when used within its rated thermal envelope.
おすすめ
Defense and Avionics Power Conditioning
Why V300B48C150BG fits: Military and avionics platforms frequently derive 270 Vdc or 300 Vdc intermediate buses from generators or rectified AC; the V300B48C150BG accepts 180-375 Vdc input and produces an isolated 48 V 150 W supply for radar processing, flight-control electronics, and electronic-countermeasure subsystems. Reinforced isolation and integrated OVP/OCP/OTP reduce secondary fault monitoring overhead in safety-critical systems. How it is used and performance: Qualified vicariously through Vicor Maxi-series heritage tests, the module is bolted to a chassis spreader plate that doubles as heatsink and EMI ground; it sustains regulated 48 V across MIL-STD-704 transient profiles when sized within rated headroom.
おすすめ
Renewable-Energy Battery Step-Down to 48 V Bus
Why V300B48C150BG fits: Solar and energy-storage inverters often produce 300-400 Vdc intermediate rails; the V300B48C150BG taps this directly to produce an isolated 48 V 150 W supply that feeds battery management boards, monitoring gateways, and auxiliary sub-systems without an extra isolation transformer. How it is used and performance: Mounted in the inverter cabinet with input fusing and pre-charge, it holds ±0.4% regulation across the generator's wide DC operating window, with surge withstand of 400 V for 100 ms to absorb inductive transients from the renewable source.
おすすめ
Medical Imaging and Diagnostic Equipment
Why V300B48C150BG fits: Medical imaging and diagnostic equipment demand reliable isolated power with strict leakage and patient-safety considerations; the V300B48C150BG's reinforced isolation and integrated protections suit ancillary subsystems such as patient-monitoring displays and imaging workstation power rails fed from a 300 Vdc medical-grade intermediate bus. How it is used and performance: Connected inside the medical chassis with documented creepage/clearance paths, it provides 88-90% efficient 48 V that downstream isolated DC-DC converters further transform to logic and analog rails; this architecture satisfies IEC 60601-1 isolation principles when cascaded appropriately within a 2 x MOPP design.
おすすめ
Datacenter 48 V Distribution Architecture
Why V300B48C150BG fits: Next-generation hyperscale datacenters are migrating to 48 V server racks to reduce distribution losses; the V300B48C150BG's 48 V 150 W output complements intermediate-bus converters for GPU blade clusters fed from 300 Vdc battery-backed distribution. Reinforced isolation meets the safety-barrier requirements of high-density rack deployments. How it is used and performance: Used as a high-side isolated brick feeding point-of-load regulators, it provides ±0.4% regulation that keeps GPU voltage rails within tolerance even under transient compute bursts, optimizing rack PUE compared with legacy 12 V architectures.

設計ノート
Recommended: Install a fast-acting high-voltage fuse on the +IN line rated for the DC input voltage with an interrupt rating above the available fault current. Estimated: with a 375 Vdc bus and 150 W load, input current is approximately 0.44 A; size the fuse so it clears before internal MOSFET damage occurs. Vicor's Maxi-series datasheet recommends a specific fuse family because the brick's internal protection assumes an external clearing device. Pair the fuse with an inrush-limiting thermistor or active pre-charge to keep input-side stress within the module's 400 V 100 ms surge rating.
Estimated: at full 150 W load and approximately 88% efficiency, the module dissipates roughly 20 W internally as heat. With the baseplate bolted to an aluminum spreader plate, verify junction and baseplate temperatures stay inside the published derating curve (typical baseplate rating -20 °C to +100 °C). For continuous full-load operation, mount the baseplate to a chassis spreader with thermal interface material and design airflow adequate to keep the baseplate below 90 °C at worst-case ambient; otherwise the internal OTP will limit usable output power.
Recommended: Keep input and output loops physically separated and minimize loop area on the PCB to reduce common-mode and differential-mode EMI. The 9-DIP through-hole leads are positioned for low-inductance bussing; route +IN and -IN as a tight differential pair from the source connector, and likewise +OUT/-OUT from the output capacitor bank to the load. Connect the baseplate ground to chassis with a low-impedance bond (star washer or conductive gasket) to provide both thermal contact and a quiet EMI reference. Maintain the creepage and clearance distances stated by Vicor in the datasheet since this product works at hazardous voltage levels.
Critical: do not exceed 400 V on the input under any condition, including during adjacent power supply turn-on or capacitor inrush. Avoid connecting input and output returns to the same chassis node unless isolation is intentionally defeated; this product is reinforced-isolated. Do not assume pin 5 (ON/OFF) polarity is active-high without checking your specific Maxi-series datasheet revision - some Vicor generations are active-low. Finally, do not operate the module without the recommended minimum output capacitance stated in the datasheet, or output ripple and stability will degrade.
コンプライアンス情報
Detailed RoHS, REACH, and lead-free status for the V300B48C150BG are not present in the verified web data; designers should request the latest material declaration from Vicor. AEC-Q100 is not applicable for this through-hole DC-DC converter module since it is not an automotive-grade IC.
