| Efficiency, typical |
87% at the stated test conditions |
230 VAC input, rated load, 25°C ambient unless otherwise stated. Ripple/noise test: 20 MHz bandwidth; 12-inch twisted-pair wire terminated with 0.1 µF and 47 µF parallel capacitors.
Voltage tolerance includes setup tolerance, line regulation and load regulation. Line regulation is measured from low to high input at rated load; load regulation is measured from 0% to 100% rated load.
Input and Timing

90 to 132 VAC / 180 to 264 VAC |
| Input range selection |
115/230 VAC selector switch |
| DC input range |
240 to 370 VDC. Set switch to 230 VAC for DC input. |
| Input frequency |
47 to 63 Hz |
| AC input current, typical |
4A/115VAC 2.2A/230VAC |
| Inrush current, typical |
Cold start 60A/115VAC 60A/230VAC |
| Leakage current |
<2mA / 240VAC |
| Setup / rise time |
1500 / 50 ms at 230 VAC; 1500 / 50 ms at 115 VAC, full load |
| Hold-up time, typical |
16 ms at 230 VAC; 12 ms at 115 VAC, full load |
| Transient input withstand |
300 VAC for 5 seconds; this is a surge condition, not the continuous input rating |
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 |
| Overload |
110 to 140% of rated output power. Hiccup; automatically recovers after fault condition is removed. |
| Overvoltage protection |
5.75 to 6.75 V. Hiccup; automatically recovers after fault condition is removed. |
| Thermal protection |
Hiccup; automatically recovers after fault condition is removed. |
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 |
20 ~ 90% RH non-condensing |
| Storage temperature / humidity |
-40 ~ +85°C, 10 ~ 95% RH |
| Temperature coefficient |
±0.03%/°C (0 ~ 50°C) |
| Operating altitude |
Up to 5,000 m as stated for this series; the applicable overvoltage category and temperature derating impose additional limits. |
| Overvoltage category |
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. |
| Higher-altitude temperature derating |
For operation above 2,000 m, reduce the permitted ambient temperature by 5 °C per additional 1,000 m. Verify the applicable insulation/approval limits for the installation. |
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 32 for this model and installation orientation.

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.
