NOTE| 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Voltage adjustment can only be operated within the input range of 100~120VAC or 200-240VAC. If the voltage adjustment is performed outside this range, it may cause abnormal output.
4. Tolerance: includes set up tolerance, line regulation and load regulation.
5. Line regulation is measured from low line to high line at rated load.
6. Load regulation is measured from 0% to 100% rated load.
7. Length of set up time is measured at cold start. Turning the power supply on/off frequently may lead to an increase of the set up time.
8. Derating may be needed under low input voltages. Please refer to”Static Characteristics” sections for details.
9. Once protections are triggered, 3min(Typ.) of cold down time is required before restart.
10. The ambient temperature derating of 5°C/1000m is needed for operating altitude greater than 2000m(6500ft).
11. This power supply does not meet the harmonic current requirements outlined by EN61000-3-2. Please do not use this power supply under the following conditions:
a) the end devices is used within the European Union, and
b) the end-devices is connected to public mains supply with 220Vac or greater rated nominal voltage, and
c) the power supply is:
– installed in end-devices with average or continuous input power greater than 75W, or
– belong to part of a lighting system
Exception:
Power supplies used within the following end-devices do not need to fulfill EN61000-3-2
a) professional equipment with a total rated input power greater than 1000W;
b) symmetrically controlled heating elements with a rated power less than or equal to 200W
12.RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1. * Product Liability Disclaimer : For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx
