产品特点 FEATURES

High reliability: No built-in aluminum or tantalum electrolytic capacitors, reducing failure risks.

High efficiency: Up to 93.5% typical efficiency (for CHS3002415 model), minimizing power loss and heat generation.

Compact design: Standard brick size (suitable for telecom market requirements), low profile, high power density.

Wide input voltage range: DC18-36V (for CHS30024 series), adapting to various power supply environments.

Stable output performance: Precise line regulation (≤30mV max) and load regulation (≤30mV max), low ripple (≤180mVp-p) and noise (≤210mVp-p).

Built-in protection circuits: Overcurrent (auto restart when exceeding 105% rated load), overvoltage (110%-130% auto restart), and thermal protection.

Flexible functional design: Built-in remote ON/OFF (negative logic: L=ON, H=OFF), remote sensing (compensates for voltage drop), output voltage adjustable via external resistor (range: -20%/+5% for CHS3002415).

Compliance and safety: CE, UKCA, RoHS directive compliant; safety approvals including UL60950-1, C-UL, EN62368-1; 5-year warranty.

Industrial automation: PLCs (Programmable Logic Controllers), DCS (Distributed Control Systems), servo drives, industrial sensors.

Test and measurement devices: Signal generators, oscilloscopes, power analyzers needing stable DC power supply.

Medical devices: Diagnostic equipment, monitoring systems (complying with safety standards).

Embedded systems: Industrial PCs, single-board computers, embedded controllers.

Transportation electronics: Railway signaling systems, in-vehicle devices (adapts to voltage fluctuations).

Renewable energy systems: Solar panel charge controllers, small wind turbine power converters (efficient energy conversion).

注意事项 PRECAUTIONS

1 Mounting: Can be installed in any direction; leave sufficient ventilation space when using multiple units to prevent overheating.

2 Wiring: Avoid placing DC input/output lines or signal lines under the unit to reduce conducted noise and ensure system stability.

3 Soldering: Follow specified parameters: Flow soldering (260°C, ≤15 seconds); Soldering iron (max 450°C, ≤5 seconds); Reflow soldering (for S option: adhere to temperature profiles and do not exceed pin terminal temperature limits).

4 Pin stress: Do not apply more than 19.6N horizontal force or 39.2N vertical force to pins; fix the unit to PCB with silicone rubber or fittings to reduce stress.

5 SMD option (S): Reflow soldering is recommended; the unit is not reusable after soldering to PCB.

6 Derating: Follow ambient temperature derating curves—reduce load current at higher temperatures (adjust based on cooling method: convection, 1m/s or 2m/s forced air).

7 Usage: Do not operate beyond rated input/output specifications; refer to the official instruction manual for detailed derating guidelines and application notes.
