180–264 VAC or 255–373 VDC. Use the correct input connection and the applicable installation instructions.
Input frequency
47–63 Hz
Power factor
>0.92 at 230 VAC and full load (typical specification).
Total harmonic distortion
<20% at 230 VAC and full load; lower-load performance depends on the load curve.
Efficiency
89% minimum at 230 VAC, as printed in the model column of the catalog efficiency row.
Typical AC input current
0.5 A at 230 VAC
Setup time
500 ms at 230 VAC and full load.

<0.25 mA maximum at 230 VAC
Measurement conditions
Unless otherwise stated: 230 VAC input, rated load, and 25°C ambient. Ripple and noise use 20 MHz bandwidth and a 12-inch twisted pair, with the catalog-specified 104PF/50V ceramic and 47 μF/50V capacitor termination.
Protection functions
Parameter
Specification
Overload protection
105–200% of rated output power; hiccup mode, with automatic recovery after the fault condition is removed.
Overvoltage protection
57.6–72 V; zener-diode clamping with output shorting, as described in the catalog.

Environment and derating
Parameter
Specification
Working ambient temperature
−20 to +50°C, subject to derating.
Ambient derating curve
Horizontal mounting: 100% load from −20 to +40°C, reducing to 70% at +50°C. Apply ambient, input and case-temperature limits together.
Case-temperature curve
The catalog output-load curve ends at Tcase 75°C. Check the actual product label for its maximum Tc and keep the marked case measurement point within that limit.
Cooling and mounting
Free-air convection. Nonstandard orientation or high ambient temperature can raise internal temperature and require output-current derating.
Input-voltage/load curve
100% load across 180–264 VAC at 50/60 Hz, within the applicable thermal limits.
Humidity and storage
Working: 20–95% RH, non-condensing. Storage: −30 to +80°C, 10–95% RH.
Temperature coefficient
±0.03%/°C over −20 to +50°C.
Altitude derating
For this fanless design, reduce the allowed ambient temperature by 3.5°C per 1000 m above 2000 m.
Vibration
10–500 Hz, 2G, 12 minutes per cycle; 72 minutes along each of the X, Y and Z axes.
Performance-curve scope
The PF, THD and efficiency plots are 24 V model examples at 230 VAC. The THD/efficiency plots use Tcase 75°C. Use the model-specific efficiency and full-load specifications above for this SKU.

Selection and installation
Parameter
Specification
Load selection
Use an LED load designed for 48 V constant-voltage operation and stay within 0.625 A / 30 W after all required derating. Confirm connector dimensions and center-positive polarity before connection.
External dimming connection
The catalog illustrates a constant-voltage adapter feeding an external DC 12–24 V PWM dimmer and LED strip. This is an output-side controller example, not a built-in AC phase-cut dimming function. Verify the controller’s input voltage, load current and output polarity. The illustrated 12–24 V controller is not suitable evidence for this 48 V output; select a controller explicitly rated for 48 V.
Installation and maintenance
Disconnect the adapter from mains before installation or maintenance, and prevent unintended reconnection. Use approved primary and secondary cables with current ratings at least equal to the unit rating. Do not immerse the unit in water or open its enclosure; faults must be examined by a qualified technician. A damaged external cable must be replaced by the manufacturer, its service agent or a similarly qualified person.
Thermal check
Keep ventilation clear, apply orientation/ambient derating, and check the marked Tc point against the maximum temperature on the product label. Do not stack objects on the unit; leave 10–15 cm clearance when an adjacent device is a heat source.
System integration
EMC depends on the complete installation. The final-equipment manufacturer must re-qualify the complete system and confirm the LED load and any controller are compatible.
