6 Comprehensive protection functions: Overvoltage (latch mode), Overload/Overcurrent (hiccup mode auto-recovery), Over Temperature (latch mode), Short Circuit (hiccup mode auto-recovery)

7 Compliance with international safety standards: UL/cUL recognized, CB scheme, EN 62368-1, EN 60950-1; EMC compliance with EN55032 Class B, EN55024

8 Low inrush current and leakage current for safe operation

9 Adjustable output voltage (10.8-13.2 Vdc) to meet diverse device requirements

使用场景 APPLICATIONS

1 Embedded systems and IoT gateways requiring stable 12V DC power

2 Industrial automation equipment (sensors, control panels) benefiting from conformal coating and wide temperature range

3 Test and measurement instruments needing low ripple noise (<150mVpp at 0-50°C) and precise voltage output

4 Consumer electronics (routers, smart home devices, set-top boxes) with universal power input compatibility

5 Commercial devices (POS terminals, display screens) due to high efficiency and long lifespan

注意事项 PRECAUTIONS

1 Installation Safety: Mount on grounded metal surface; maintain safety distance (Open Frame: ≥8mm from primary side/≥4mm from secondary side; Enclosed/L Frame: ≥4mm all sides) or use insulation sheet if distance is insufficient.

2 Operating Conditions: De-rate power output as per temperature (e.g., Open Frame:2.5%/°C above50°C; Enclosed:2.5%/°C above40°C); avoid operating beyond -10°C~70°C (operating) or -25°C~75°C (storage).

3 Handling: Do not twist/bend PCB; keep foreign objects (metal, dust, liquid) away to prevent short circuits.

4 Protection Triggers: For latch-mode protections (OTP/OVP), disconnect AC input, resolve fault (reduce load/temp), then reapply power; auto-recovery protections (overload/short circuit) resume after fault removal.

5 Maintenance: Do not disassemble the power supply to preserve safety certifications.
