V110A24C400BG Übersicht
An isolated module DC-DC converter is a fully self-contained power conversion block that combines a switching regulator, isolation barrier, transformer, output filter, and control loop into a single encapsulated brick. Designers use brick converters to step a high-voltage DC bus down to a low-voltage rail while maintaining galvanic isolation between source and load. This category sits within the broader hierarchy of switch-mode power supplies (SMPS) -> DC-DC converters -> isolated modules -> board-mount power modules, and is preferred over discrete switching designs when PCB area is at a premium and a UL/IEC safety isolation rating is required.
Key features of the V110A24C400BG include a continuous input voltage range of 66 V to 154 V (with 250 V surge withstand capability), programmable output voltage from 2.4 V to 26.4 V, output power of 400 W, typical efficiency in the high-80% to low-90% range, and operation across -20°C to +100°C baseplate temperature. The encapsulated Full Brick package provides mechanical robustness against shock and vibration, and the ZCS/ZVS switching architecture delivers high power density with low EMI signature.
Architecturally, the V110A24C400BG uses Vicor's sine-amplitude converter topology (a soft-switching resonant topology) where the primary side MOSFETs switch at zero voltage and the secondary-side MOSFETs switch at zero current. This eliminates the major switching-loss mechanisms of hard-switched PWM converters, enabling high switching frequencies (typically ~1 MHz) without the usual efficiency penalty, which in turn shrinks the magnetics and output filter.
Typical applications for this part include industrial 110 V/220 V rectified-bus distributed systems, railroad and transit auxiliary power, telecom 48 V/130 V backplane converters, high-end test and measurement equipment, and any embedded board requiring an isolated 24 V rail from a high-voltage front-end supply. The wide input range also makes it well suited to 110 V nominal rectified industrial three-phase systems.
When designing with this part, pay close attention to the input bus capacitance requirement and the recommended input fuse rating; Vicor's datasheet specifies minimum hold-up capacitance for ride-through of input dropouts. The baseplate must be properly heatsinked - the Full Brick dissipates substantial power at full load, and insufficient cooling will trigger the internal thermal shutdown.

Typische Anwendungen
V110A24C400BG ist geeignet für 6 Anwendungs: Industrial 110V/220V Rectified Bus Power, Railroad and Transit Auxiliary Power, Telecom 48V/130V Backplane Conversion, Test and Measurement Equipment, High-End Industrial PCs and Embedded Servers, Renewable Energy and Battery Storage Systems.
Industrial 110V/220V Rectified Bus Power
The V110A24C400BG is purpose-built for industrial systems that rectify 110 VAC or 220 VAC single-phase mains to a ~155 V DC bus and need an isolated 24 V/16.67 A rail. Its 66 V to 154 V continuous input range tolerates wide bus swings under varying line and load conditions, while the 250 V surge withstand rating absorbs the inrush spikes common to rectified industrial supplies. Placed between the front-end rectifier and downstream 24 V loads such as PLCs, motor drives, and industrial PCs, it delivers 400 W at 24 V with full galvanic isolation, eliminating the need for a custom isolated DC-DC design. The Full Brick baseplate mounts directly to a chassis wall or heatsink, simplifying mechanical integration in control cabinets.

Railroad and Transit Auxiliary Power
The 66-154 V input range of the V110A24C400BG matches the nominal 110 V DC bus used in many railroad and transit auxiliary power systems, where 24 V rails power lighting, communications, door controls, and passenger-information displays. The encapsulated Full Brick package resists shock and vibration per the Vicor datasheet, which is critical for rolling-stock qualification. With 400 W available, one brick can supply a full auxiliary-power sub-rack without paralleling. The ZCS/ZVS switching topology keeps EMI low, easing compliance with railway EMC directives like EN 50121.
Empfohlen
Telecom 48V/130V Backplane Conversion
Central-office telecom systems often distribute a -48 V or +130 V battery-backed bus and need isolated 24 V intermediate rails for line cards, baseband processing, and fan trays. The V110A24C400BG accepts the 130 V telecom bus directly and converts it to an isolated 24 V/16.67 A rail with 400 W capacity, replacing bulky discrete forward or flyback designs. Its high efficiency at partial load suits the variable-fan-power profile of telecom shelves, and the Vicor Maxi baseplate simplifies heatsink attachment in the dense backplane environment. Designers commonly place two bricks in parallel with Vicor's ORing diodes for N+1 redundancy.
Empfohlen
Test and Measurement Equipment
High-end bench and ATE power supplies, oscilloscopes, and signal analyzers need clean isolated 24 V rails to power analog front-ends, ADC/DAC boards, and display subsystems. The V110A24C400BG delivers 400 W at 24 V from the instrument's universal-input front end with full galvanic isolation, protecting sensitive measurement circuits from ground loops. The ZCS/ZVS topology produces low EMI, which is critical when the instrument must meet CE/FCC radiated-emission limits while measuring microvolt-level signals. The programmable output (2.4 V to 26.4 V via the trim pin) lets the same brick serve multiple internal rails across product variants.

High-End Industrial PCs and Embedded Servers
Industrial PCs, edge servers, and machine-vision controllers often accept 24 V from a chassis backplane and need isolated intermediate rails for PCIe cards, NVMe storage, and PoE subsystems. The V110A24C400BG accepts the wide 66-154 V factory bus directly, providing an isolated 24 V/16.67 A rail that downstream point-of-load converters further step down to 12 V, 5 V, and 3.3 V. The Full Brick form factor fits comfortably in the chassis alongside the motherboard, and the metal baseplate conducts heat directly to the chassis wall for fanless cooling in sealed enclosures.
Empfohlen
Renewable Energy and Battery Storage Systems
Solar inverters, wind-turbine converters, and battery-energy-storage cabinets operate from high-voltage DC buses (typically 100 V to 150 V stack voltages) and need isolated auxiliary rails to power gate drivers, fans, and control boards. The V110A24C400BG interfaces directly to the high-voltage stack and provides an isolated 24 V/16.67 A rail that survives the bus-voltage swings of lead-acid or lithium battery banks. Its 250 V transient withstand rating handles the inductive kickbacks common in solar and motor-control environments, and the Full Brick's encapsulated construction tolerates the humidity and temperature cycling typical of outdoor renewable installations.

Wichtigste Unterscheidungsmerkmale
- Vicor Maxi family drop-in compatibility (vs. V110A24C400BL)
- Higher power density vs cross-voltage siblings (vs. V72A5C300BS3)
- Wide 66-154V input for direct rectified-bus operation (vs. V24A5C400BL)
Designhinweise
Estimated: at full 400 W load with 88% typical efficiency the V110A24C400BG dissipates roughly 54 W into the Full Brick baseplate. With a typical theta_JB of ~0.4 °C/W for the Full Brick package, the junction-to-baseplate rise is approximately 22°C. Mount the baseplate to a chassis wall or external heatsink with thermal compound; for continuous full-load operation at 100°C baseplate a forced-air flow of ~200 LFM is recommended per the Vicor Maxi datasheet. Insufficient cooling will trigger the internal thermal shutdown and reduce field reliability.
Route input and output return paths directly to the module -IN and -OUT pins to avoid high-frequency switching currents flowing through shared ground planes, which can inject noise into sensitive analog circuits. Place input bulk capacitance per the manufacturer datasheet, plus a low-ESR ceramic close to the +IN/-IN pins to clean up the high-frequency ripple. Keep the TRIM and SC pins away from switching nodes and shield them with ground traces to avoid injection of switching noise into the control loop.
Common pitfalls with the V110A24C400BG include: (1) omitting the manufacturer-recommended input fuse, which is required because the module's low-impedance input can draw massive inrush current when the bulk capacitor charges; (2) connecting the output return and input return together externally, which defeats the galvanic isolation rating; (3) using the trim pin to set the output below 2.4 V or above 26.4 V, which is outside the supported range and can damage the internal PWM controller; (4) neglecting to provide a heatsink or assuming natural convection is sufficient - at 400 W the Full Brick baseplate requires deliberate cooling.
