| Input frequency |
47 to 63 Hz |
| AC input current, typical |
4.1A/115VAC 2.4A/230VAC |

Full load; setup at cold first start. Rapid on/off cycling can increase setup time.
Select the correct 115/230 VAC input range before energizing the supply. For DC input, the selector must be set to 230 VAC.
Protection and Recovery
| Short-circuit protection |
Included |
| Sustained overload |
Output power >105% rated for more than 5 seconds: shut down output; re-power on to recover. |
| Above 200% rated output power |
Hiccup mode; automatically recovers after fault condition is removed. |
| Overvoltage protection |
13.8 to 16.2 V. Shut down and latch off output; re-power on to recover. |
| Thermal protection |
Shut down and latch off output; re-power on to recover. |
Short-Duration Peak Loads
| Maximum peak capability |
Up to 200% of rated output power, limited by the input-voltage/peak-power curve |
| Peak duration |
5 seconds maximum per pulse |
| Duty at the 200% operating point |
20% maximum according to the family duty curve; the input-voltage curve must also allow this peak |
| Other peak operating points |
Apply the corresponding duty curve; the overall duty ceiling is 35% |
| Cycle-average power |
Must not exceed 204 W rated output power |
| Duty and average-power calculation |
Duty = t/T × 100%. Average power = [Ppeak × t + Pnon-peak × (T − t)] / T. Here t is peak duration and T is the full cycle period. |
All limits apply together. Input voltage, operating temperature, non-peak load and cycle time determine the usable peak. Check the graphs and function manual on PDF page 37; a 200% capability does not permit continuous operation at twice rated power.
Environment and Cooling
| Ambient operating temperature |
-25 to 70 °C; apply the temperature and input-voltage derating curves |
| Cooling |
Free-air convection; no fan |
| Working humidity |

| Temperature coefficient |
±0.03%/°C (0 ~ 50°C) |
| Operating altitude |
Up to 2,000 m as stated for this series; the applicable overvoltage category and temperature derating impose additional limits. |

Category III up to 2,000 m under the standards specified in this series datasheet. This is an insulation category, separate from the output-overvoltage protection threshold. |
Full rated output is not available at every point within the temperature and input ranges. Use the ambient-temperature and static input-voltage curves on PDF page 36 for this model and installation orientation.

Use the mechanical drawing on PDF page 38 to locate the holes and confirm the permitted screw penetration for the selected mounting face. The M3/M4 callouts are mounting dimensions, not accessory ordering codes. Match wiring, protective-earth connection and output polarity to the terminal markings. Keep ventilation openings clear for convection cooling.

Application and Datasheet Notes
The manufacturer states that this supply does not meet EN61000-3-2 harmonic-current requirements. Do not use it in end equipment within the European Union that is connected to public mains rated at 220 VAC or above when the end equipment has average or continuous input power greater than 75 W, or when it forms part of a lighting system. The datasheet lists exceptions for professional equipment with total rated input power greater than 1,000 W and for symmetrically controlled heating elements rated at 200 W or less. Confirm the applicability to the complete end equipment.
EMC results are for a component installed on the manufacturer’s specified test plate. The finished equipment must be checked again for EMC compliance. Safety approvals and regional exceptions depend on the exact model and datasheet revision; refer to the linked specification and applicable certificates when selecting the unit.
