产品特点 FEATURES

1 Compact half-brick form factor, compliant with telecom market standard size, ensuring high density for space-constrained applications.

2 High efficiency: 80% typical at rated DC48V input and full load, reducing energy loss.

3 High reliability: No built-in aluminum or tantalum electrolytic capacitors, minimizing long-term failure risks.

4 Adjustable output voltage: Supports 1.98-3.63V range via external resistor (fixed output when TRM pin is open).

5 Comprehensive protection: Integrated overcurrent (auto-recovers above105% rated load), overvoltage (4.00-5.50V range for3.3V output), and thermal protection circuits to safeguard the module and connected devices.

6 Convenient control functions: Built-in remote ON/OFF (negative logic: L=ON, H=OFF) and remote sensing capabilities for flexible system integration.

7 Easy installation: Equipped with M3 tapped mounting holes; compact dimensions (57.9x12.7x61.0mm) and max weight of83g facilitate integration into various systems.

8 Compliance & certifications: CE, UKCA marked; adheres to Low Voltage Directive, RoHS Directive, Electrical Equipment Safety Regulations, and RoHS Regulations; certified by UL60950-1, C-UL, and TuV; backed by a5-year warranty for long-term reliability.

9 Efficient cooling: Designed for conduction cooling via the aluminum base plate to attached heat sinks, ensuring optimal thermal performance.

使用场景 APPLICATIONS

1 Telecom infrastructure: Power supply for components in communication base stations, routers, switches, and network access devices.

2 Industrial automation: Provides stable3.3V power to PLCs, sensors, control modules, and embedded systems in industrial control environments.

3 Test & measurement equipment: Integrated into test instruments to deliver consistent power for accurate and reliable measurements.

4 Data center devices: Supports power needs of server components, storage systems, and network hardware in data centers.

5 Embedded computing: Used in single-board computers, IoT devices, and other embedded systems requiring efficient DC-DC conversion from36-76V to3.3V.

注意事项 PRECAUTIONS

1 Installation guidelines:

2 Use conduction cooling (e.g., attach a heat sink to the aluminum base plate) to maintain optimal operating temperature; refer to derating curves based on base plate temperature to avoid performance degradation.

3 Do not apply excessive stress to input/output pins (follow specified limits) to prevent internal connection damage; avoid bending or pulling pins with force.

4 Soldering requirements: Flow soldering at260°C for up to15 seconds; soldering iron (26W) at450°C for up to5 seconds; fix the module with mounting screws before soldering pins to protect PCB patterns.

5 Use M3 screws for mounting with a maximum torque of0.49N·m (5.0kgf·cm) to ensure secure installation without damage.

6 Operation precautions:

7 Avoid passing DC input/output patterns underneath the module to reduce noise; keep patterns away from the module.

8 Use a copper shield pattern on the PCB connected to the CASE pin or mounting hole to minimize radiated high-frequency noise.

9 Reduce temperature fluctuations to extend thermal fatigue life, especially in power cycle applications.

10 Do not operate the module in hatched areas of derating curves as this increases ripple and noise levels.

11 Safety & maintenance:

12 Read the official instruction manual (https://www.cosel.co.jp/redirect/catalog/en/CBS/) and safety guidelines before use.

13 Ensure operating conditions are within specified ranges: -40 to+100°C (aluminum base plate temperature),20-95% RH (non-condensing), and up to3000m altitude.

14 Do not exceed rated input/output parameters (36-76V input,3.3V/11.7A output) to prevent module damage or safety hazards.
