产品特点 FEATURES

1 High efficiency up to 95% (CHS3804812H variant), minimizing power dissipation and operational heat.

2 Compact brick-type form factor, conforming to telecom industry standard dimensions for seamless integration into existing systems.

3 Enhanced reliability: No internal aluminum or tantalum electrolytic capacitors, reducing failure risks and extending service life.

4 Comprehensive built-in protections: Overcurrent (activates above 105% of rated current), overvoltage (115%-135% of rated output voltage), and thermal protection.

5 Remote ON/OFF functionality (negative logic: L=ON, H=OFF) and remote sensing capability to maintain precise output voltage under varying load conditions.

6 Output voltage adjustability: Can be modified via external resistor within a -10% to +10% range (when utilizing the TRM pin).

7 Global safety certifications: UL60950-1, C-UL (CSA60950-1), EN62368-1, ensuring compliance with international electrical safety norms.

8 Regulatory compliance: CE marking, UKCA marking, RoHS Directive, and Low Voltage Directive adherence.

9 Long-term warranty: 5-year coverage for quality assurance and peace of mind.

10 Isolated design: Input-output isolation of DC2250V or AC1000V (1 minute duration), enhancing system safety.

11 Option U characteristic: Triggers a shutdown (not auto-restart) when protection circuits are activated, requiring fault resolution before reoperation.

使用场景 APPLICATIONS

1 Telecom infrastructure: Power supply for base stations, optical communication equipment, and network routers, leveraging its standard form factor and efficiency.

2 Industrial automation: Suitable for PLCs, motor control systems, and sensor networks needing stable 12V DC from a 36-76V DC input.

3 Data centers: Used in server racks and storage units to convert high-voltage DC to low-voltage for internal components.

4 Embedded systems: Compact size ideal for medical devices, test and measurement instruments, and portable electronic equipment.

5 Outdoor applications: Wide operating temperature range (-40°C to +85°C) enables use in harsh environments like outdoor monitoring systems and weather stations.

6 Renewable energy systems: Can be integrated into solar or wind power systems to convert battery voltages (36-76V) to 12V for auxiliary devices.

注意事项 PRECAUTIONS

1 Mounting guidelines: Avoid excessive stress on pins (horizontal ≤19.6N, vertical ≤39.2N for non-SMD variants); ensure adequate spacing between units for ventilation.

2 Soldering precautions: Flow soldering should not exceed 260°C for more than 15 seconds; soldering iron use limited to 450°C for ≤5 seconds. For SMD options, follow recommended reflow profiles.

3 Derating compliance: Adhere to ambient temperature and input voltage derating curves—reduce load current at high temperatures or low airflow to prevent overheating.

4 Circuit layout: Do not place input/output/signal lines directly beneath the unit to minimize electromagnetic interference and noise.

5 Protection handling: Due to option U, the device shuts down upon protection trigger (overcurrent, overvoltage, thermal). Resolve the root cause (e.g., overload, voltage spike) before restarting.

6 Environmental limits: Operate within -40°C to +85°C (non-condensing) and store between -40°C to +100°C. Avoid exposure to condensation or mechanical shock exceeding 20G.

7 Component care: Transformer cores, choke coils, and base plates (if option B is included) are glue-attached—avoid dropping or applying strong impacts to prevent damage.
