V375A36C400BF2 概述
An isolated DC-DC converter module is a fully encapsulated switching power supply that takes an unregulated high-voltage DC rail and produces a regulated, galvanically-isolated low-voltage DC output. In the broader power conversion hierarchy, this device sits as a 'brick converter' under the DC-DC Converter > Power Module > Power Management IC taxonomy. Brick modules are favored for distributed power architectures in industrial, railway, defense, and telecom equipment because the isolation barrier, filtering, regulation, and protective features are integrated into a single, agency-recognized package.
Key features include ultra-wide 250 V to 425 V input range, programmable output to 110% of nominal, ±0.25% line/load regulation from no load to full load, 500 V transient surge withstand on the input, and industry-standard brick pinout. The Maxi/Mini platform is also parallelable with N+M fault tolerance for higher-power or redundant operation, and auxiliary features such as remote sense and INHIBIT/ENABLE simplify integration into larger power systems.
Technically, the module uses Vicor's proprietary zero-current-switching (ZCS) zero-voltage-switching (ZVS) fixed-frequency topology to achieve high efficiency (typically 84-87% at 36V/400W full load) and low EMI signature compared to hard-switched designs. The internal current-mode control loop, combined with feed-forward input voltage compensation, holds output regulation within ±0.25% across the full specified input range and load step transients - a level of accuracy rarely achieved by open-loop module designs.
Typical applications of the V375A36C400BF2 include industrial 3-phase 380 VDC bus power systems, railway rolling-stock auxiliary supplies, high-voltage battery-fed telecom equipment, semiconductor test instrumentation, and any system that converts a high-voltage DC link into an isolated 36 V intermediate bus. The wide input range also makes it compatible with 400 V-class nominal PFC output stages found in three-phase UPS and energy-storage inverters.
When designing with this part, always observe the 4250 VDC isolation rating and route high-voltage traces with appropriate clearance per IEC/UL 60950-1 or IEC 62368-1, provide a minimum 50 CFM airflow for full 400 W output, and verify baseplate temperature stays below 100 °C under worst-case conditions. According to the Vicor datasheet, the trim pin can adjust output from 0% to 110% of nominal, but operation below 50% Vout reduces regulation accuracy - this page synthesizes distributor pricing, brick-converter drop-in alternatives, and thermal/PCB design guidance beyond what is found in the manufacturer datasheet.

典型应用
V375A36C400BF2 适用于 6 应用s: Industrial 3-Phase 380 VDC Bus Power Distribution, Railway Auxiliary Power Supplies, High-Voltage Battery-Equipped Telecom Equipment, Semiconductor Test & Measurement Instrumentation, Solar / Energy-Storage Inverter Auxiliary Power, Industrial Process Control and PLC Cabinets.
Industrial 3-Phase 380 VDC Bus Power Distribution
The V375A36C400BF2's 250 V to 425 V input range is precisely matched to a rectified three-phase 380/400 VAC industrial DC bus, and its 4250 VDC isolation per the Vicor datasheet satisfies IEC 62368-1 reinforced insulation for factory-floor equipment. The module delivers an isolated 36 V at 11.1 A (400 W) that can directly feed downstream 24 V or 48 V POL converters or motor-driver low-voltage rails. Drop the brick directly onto the factory DC link and you eliminate the intermediate AC-DC stage, reducing system BOM and avoiding line-frequency magnetics.
推荐
Railway Auxiliary Power Supplies
Railway rolling-stock auxiliary converters accept a nominal 750 VDC or 1500 VDC catenary-linked bus and must provide low-voltage isolated outputs for lighting, control electronics, and battery charging. The V375A36C400BF2's 425 VDC continuous input headroom and 500 V transient withstand for 100 ms per the manufacturer datasheet suit the DC link variations typical of locomotive head-end power systems. Its ±0.25% regulation and conductive-cooling baseplate simplify integration into the vibration-tolerant, conformal-coated enclosure environment that railway safety standards demand.
推荐
High-Voltage Battery-Equipped Telecom Equipment
Central-office telecom equipment powered from 48 V battery strings increasingly uses 380 VDC intermediate buses for higher rack distribution efficiency. The V375A36C400BF2's 250-425 VDC input window feeds from 380 VDC PFC rails with the plus/minus headroom needed during battery charge/discharge swings. The brick's 4250 VDC isolation and 400 W continuous rating handle a complete subrack of distributed DSP/FPGA compute or 5G baseband modules on its own, with N+M parallelability per the Vicor datasheet enabling graceful maintenance.
推荐
Semiconductor Test & Measurement Instrumentation
ATE and precision parametric testers need highly stable, isolated low-voltage rails for DUT biasing and reference generation. The V375A36C400BF2's ±0.25% regulation from no load to full load and programmable output to 110% of nominal (per the Vicor datasheet) enable fine-tuning of test voltages without auxiliary regulators. The 4250 VDC isolation barrier keeps noisy 3-phase rectifiers away from low-level measurement front-ends, and the 36 V intermediate bus is ideal for powering precision analog rails in vector signal generators and source-measurement units.
推荐
Solar / Energy-Storage Inverter Auxiliary Power
Three-phase photovoltaic and battery inverters generate a 600-1500 VDC link that must be stepped down to low-voltage rails for gate drivers, controllers, and protection relays. The V375A36C400BF2 operates directly from the lower end of this DC link (250-425 V range) per its datasheet, delivering an isolated 36 V for the control-electronics subsystem. Hot-swap-friendly N+M parallelability supports 24/7 availability demanded by grid-tied solar-storage installations, where downtime equals lost revenue.
推荐
Industrial Process Control and PLC Cabinets
PLC cabinets and process controllers commonly accept a 380-400 VAC three-phase input and must run 24 VDC control electronics, motor contactors, and HMI displays. The V375A36C400BF2 converts the rectified 3-phase bus directly to an isolated 36 V intermediate rail (per Vicor datasheet) that can be further regulated to 24 V with high-efficiency downstream converters. The brick's conductive baseplate cooling, full regulatory isolation, and ±0.25% regulation contribute to the long-term reliability expected in unattended industrial process installations such as chemical plants and refineries.

设计说明
Estimated: at 36V full load (~11.1A) the module dissipates on the order of 60-70W, meaning the baseplate must be coupled to a heatsink capable of holding baseplate temperature below 100 °C. For still-air desktop systems with a 4-6 in² finned heatsink, derate output to ~250 W; for full 400 W output the manufacturer datasheet recommends a baseplate temperature held to ≤100 °C, typically achieved with ≥50 CFM forced airflow or a liquid-cooled cold plate. Always measure the hottest spot on the baseplate, not the centre, because thermal gradients can shift under load.
Per the Vicor Full Brick pinout (the package has no PCB-level signals; all connections are made through the integrated pins/posts), observe at least 8 mm of clearance between input-side and output-side traces, and at least 4 mm of creepage on the PCB between high-voltage input pins and low-voltage output pins per IEC 62368-1. Avoid routing any signal trace within 6 mm of the mounting hardware, since the screws serve as the safety-ground bond for the chassis connection.
A common design pitfall is omitting the input fuse and reverse-polarity protection, even though the brick itself has internal input overcurrent limiting. The brick does not block DC reverse polarity on its input, so always place an external input fuse and reverse-blocking diode or active OR-ing MOSFET in series with the input. Also avoid operating the brick below the 50% Vout trim point for extended periods - the output ripple and regulation accuracy degrade below this trim level per the manufacturer datasheet.
Use twisted-pair or closely-coupled wiring for input and output leads to minimize radiated EMI from the high-di/dt switching current paths. According to the Vicor Maxi/Mini datasheet, the brick has internal input/output Y-capacitors that significantly reduce the line-frequency common-mode current, but the chassis still benefits from a safety-ground bond at the input connector shell. Keep the +OUT and -OUT twisted pairs inside the chassis and route them away from any sensitive analog signal paths.
