V375A36T400BL - 400W 36V Isolated DC-DC Converter | Vicor
MPN: V375A36T400BL ✓ Hoạt độngV375A36T400BL Tóm tắt
An isolated DC-DC converter is a switched-mode power module that uses a high-frequency transformer to provide galvanic isolation between input and output while stepping a high-voltage DC bus down to a lower voltage rail. Within the power-conversion hierarchy, isolated converters sit alongside non-isolated POL regulators and AC-DC front ends, and they are typically deployed after PFC and bulk-capacitor stages in distributed-power architectures. The V375A36T400BL belongs to Vicor's Maxi family, which is known for high efficiency, low noise, and rugged operation in industrial, military, and aerospace power systems.
Key specifications include an output current of 11.1A (400W total), an input range of 250V to 425V DC (375V nominal), an input-surge withstand of 500V for 100ms, output regulation of ±0.35% no-load to full-load, and high-speed MOSFET switching topology. The module also features an isolated output, programmable output trim, and a typical conversion efficiency in the mid-80% to low-90% range depending on operating point. The through-hole package provides robust mechanical mounting for chassis and PCB backplane designs in harsh environments.
The V375A36T400BL uses Vicor's proprietary Sine Amplitude Converter (SAC) topology or a similar high-frequency resonant topology to achieve soft switching and high power density. This topology minimizes switching losses and reduces EMI relative to hard-switched PWM converters, making the module suitable for noise-sensitive analog and RF subsystems sharing the same chassis.
Typical applications include industrial 380V rectified-bus distribution, railway rolling-stock auxiliary power, high-voltage battery energy storage, military C4ISR platforms, and telecom -48V/-60V central-office equipment. The wide 250-425V input range makes the module well suited to nominal 300V, 330V, or 400V intermediate bus voltages generated from three-phase PFC front ends.
When integrating this module, ensure the upstream bulk capacitance meets the input-ripple and inrush requirements specified in the datasheet, and verify that the host PCB thermal design keeps the module baseplate below its maximum operating temperature.

Ứng dụng tiêu biểu
V375A36T400BL phù hợp cho 7 Áp dụngs: Industrial 380V Rectified-Bus Distribution, Railway Rolling-Stock Auxiliary Power, High-Voltage Battery Energy Storage Systems, Military / Aerospace C4ISR Platforms, Telecom Central-Office Power, Industrial Laser and Plasma Power, Test and Measurement Instrumentation.
Industrial 380V Rectified-Bus Distribution
The V375A36T400BL's 250-425V input range is purpose-built for rectified 3-phase industrial buses after PFC, making it ideal for factory-automation cabinets, drives, and process-control PLCs. With 36V at 11.1A, it powers 36V industrial stepper/servo motor drivers, valve actuators, and 24V-class industrial sensors through a downstream buck converter. The 500V/100ms surge withstand protects against load-dump and switching transients common in industrial substations. Its isolated output allows the 36V rail to be tied to chassis ground or floated, simplifying EMI and safety design inside large factory power cabinets.

Railway Rolling-Stock Auxiliary Power
The V375A36T400BL is widely deployed on railway rolling stock and trackside cabinets that operate from 600V/750V rectified bus voltages after the PFC and DC-link stage. The 36V output drives relay coils, lighting inverters, door-control electronics, and onboard diagnostics, while the 500V surge withstand meets EN 50155 transient requirements. Galvanic isolation lets the 36V rail be referenced to chassis, critical for traction systems where grounding topology is tightly controlled. A typical installation places this module behind a Vicor or third-party input EMI filter and a pre-charge / inrush-limiting circuit.

High-Voltage Battery Energy Storage Systems
In 400V-class battery energy storage systems (BESS) and solar inverters, the V375A36T400BL steps the high-voltage DC bus down to a 36V intermediate rail for downstream conversion to battery-cell voltages, monitoring electronics, and cooling fans. The 250-425V input tracks the typical BESS DC-link voltage during charge, discharge, and idle, while the 11.1A output delivers 400W of headroom for auxiliary loads. Isolation between the battery stack and the 36V rail is essential for service technician safety during field maintenance.

Military / Aerospace C4ISR Platforms
The V375A36T400BL's rugged through-hole Maxi brick package, high efficiency, and surge-withstand rating make it a strong fit for military and aerospace C4ISR, EW, and radar subsystems operating from 270V DC nominal or 400Hz rectified AC buses. The 36V output feeds RF power-amplifier rails, ruggedized displays, and signal-processing cards. Its isolated output simplifies EMI zoning in tightly packed, multi-domain enclosures. For flight-critical programs, screen the module against MIL-STD-704 and MIL-STD-810 before deployment.

Telecom Central-Office Power
In -48V/-60V telecom central offices, a 380V DC intermediate bus is increasingly used to feed isolated brick converters like the V375A36T400BL that produce 36V sub-rails for PoE midspans, RF power amplifiers, and base-station radio cards. The 36V rail can feed downstream POL converters or directly drive 36V-tolerant telecom ASICs. Isolation from the 380V bus is mandatory for safety and for separating noisy digital returns from clean RF grounds inside the same shelf.
Được đề xuất
Industrial Laser and Plasma Power
The V375A36T400BL's 400W output and 36V rail are well matched to diode-laser stacks, plasma generators, and induction-heating front ends used in industrial cutting, welding, and additive-manufacturing equipment. The 36V bus feeds laser-diode driver boards that regulate current through each emitter, while the isolated topology protects low-voltage control electronics from high-voltage noise generated by the laser driver. Surge withstand protects the module from the violent load transients characteristic of plasma-arc systems.
Được đề xuất
Test and Measurement Instrumentation
High-end benchtop and ATE test-and-measurement instruments (spectrum analyzers, signal generators, modular chassis like PXI/LXI) use 400W-class brick converters such as the V375A36T400BL to derive clean, isolated 36V rails from a universal 110-380V DC internal bus. The 36V rail feeds high-resolution ADC/DAC boards, FPGA DSP cards, and display subsystems that demand low-noise power. Isolation keeps noisy digital grounds separate from clean analog grounds, critical for measurement integrity at microvolt-level signal paths.

Bảo phân biệt quan trọng
- True 400W output in the Vicor Maxi brick form factor (vsLower-power Vicor Mini (200W) or Micro (100W) bricks)
- Wide 250-425V input designed for 380V rectified industrial bus (vs48V-input converters (e.g. POL modules))
- 500V/100ms input surge withstand (vsLower-rated industrial converters (typically 400V/100ms))
Ghi chú thiết kế
Estimated: at 400W output with ~88% efficiency, internal dissipation is roughly 55W. With a Vicor Maxi brick baseplate thermal resistance of approximately 1 C/W to a properly heatsunk chassis, the baseplate-to-ambient rise is ~55C, so the chassis must be sized to keep the baseplate below the datasheet maximum (typically 100C). Always mount the brick to an aluminum or copper heatsink with thermal compound and verify with a thermocouple in production.
Use a 4-layer PCB with at least 2oz copper on input and output power layers. Place input bulk capacitors (typically 1-2 x 2.2uF X7R ceramics + 33-100uF electrolytic) within 0.5 inch of the Vin+ and Vin- pins. The +Sense and -Sense traces must be routed as a Kelvin pair to the output capacitors, not shared with power-return traces, or load regulation will degrade below the ±0.25% datasheet figure.
Do not exceed 425V continuous or 500V transient on the input - the input capacitors and MOSFETs have no further margin. Always populate the recommended inrush-limiting NTC or active circuit at turn-on, otherwise the bulk-cap charging current can trip upstream protection. Leave the Gate-In and Gate-Out pins open unless you are synchronizing multiple bricks for parallel operation; accidental termination can cause instability.
