产品特点 FEATURES

Vicor V375B8H200BG DC-DC converter module belongs to the 375V Mini Family, with the following key features:

1 Wide DC input range: 250-425V DC, supporting input surge withstand of up to 500V DC for less than 100ms.

2 Isolated output design: Provides 3000VRMS isolation between input and output, 1500VRMS between input and baseplate, and 500VRMS between output and baseplate, ensuring safe operation.

3 Stable output performance: Nominal output voltage 8V DC, rated power 200W (max load current 25A); output regulation is ±0.3% from no load to full load, ensuring consistent power supply.

4 Programmable output: Supports output voltage adjustment in the range of 10-110% of nominal value, flexible for different application needs.

5 High efficiency and power density: Adopts low-noise ZCS/ZVS architecture, standard efficiency up to 84.2% (at nominal input, 75% load, 25°C); power density reaches up to 120W per cubic inch, saving installation space.

6 Robust temperature tolerance: H-grade module with operating temperature range of -40 to +100°C (full load at 100°C) and storage temperature range of -55 to +125°C, suitable for harsh environments.

7 Parallelable capability: Supports N+M fault tolerance when paralleled, enabling scalable power solutions (follow design guide for correct interface methods).

8 RoHS compliant: Equipped with G pin option (long RoHS gold-plated pins), meeting environmental requirements.

9 Agency approvals: Compliant with cURus, cTÜVus, CE, UKCA standards (UL60950-1, EN60950-1 etc.), ensuring product safety and reliability.

10 Low noise: Ripple and noise up to 400mV P-P (at nominal input, full load, 20MHz bandwidth), reducing interference to connected devices.

使用场景 APPLICATIONS

This converter module is suitable for various industrial and commercial applications, including:

1 Off-line systems with auto-ranging or PFC front ends: Can be used as a core power component in systems requiring stable DC power conversion from high-voltage inputs.

2 Industrial and process control: Ideal for powering control circuits, sensors, actuators in factory automation lines, manufacturing equipment, and process control systems.

3 Distributed power systems: Used in distributed power architectures to provide localized, stable power to different subsystems.

4 Medical equipment: Suitable for powering non-life-support medical devices (after confirming compliance with relevant standards) such as diagnostic tools, laboratory equipment.

5 ATE (Automatic Test Equipment): Provides reliable power for test instruments, ensuring accurate and consistent test results.

6 Communications infrastructure: Used in telecom equipment power systems to convert high-voltage DC to the required low-voltage power for communication modules.

7 Laboratory setups: Suitable for R&D labs needing adjustable, stable DC power supplies for prototype testing and circuit validation.

注意事项 PRECAUTIONS

When using this converter module, please note the following:

1 Temperature limits: Do not operate the module above the maximum operating temperature of 100°C (full load); the module will shut down if overheated, and periodic checks are recommended to ensure proper heat dissipation.

2 Input voltage: Do not exceed the input voltage range of 250-425V DC; input surge should not exceed 500V DC for more than 100ms to avoid damage.

3 Output limits: Do not exceed the rated output power (200W) or maximum load current (25A); dynamic loading exceeding 25% of rated current requires consultation with Vicor applications engineering.

4 Remote sense connection: Ensure sense leads are connected to respective output terminals; total voltage drop should not exceed 0.5V (0.25V per leg) to maintain regulation accuracy.

5 Output trimming: When trimming output voltage, trim down reduces available power (constant current limit), and trim up should not exceed +10% of nominal voltage to prevent overvoltage protection activation.

6 Parallel operation: Follow the design guide for correct parallel interface methods (AC-coupled for up to 3 modules, transformer-coupled for more) to ensure proper current sharing.

7 Soldering and mounting: Adhere to soldering specs (wave solder <5sec at 260°C, hand solder <7sec at 390°C); use correct mounting torque (5in.lbs/0.57N.m) for secure installation.

8 Storage: Store the module in ESD-safe packaging in an environment with temperature 15-38°C and non-condensing humidity; avoid exposure to extreme temperatures or moisture.

9 Safety approvals: Ensure the module is used with appropriate fuses in series with the +Input terminal to comply with agency standards.
