EN61000-3-2 harmonic current
EN61000-3-2 describes the permissible harmonic current emissi
ons for devices with an input current of up to 16 A per phase.
LED driver with less than 25Watt has no limit values for harmoni
c.
In case the Driver has an effective input power larger than 25 W,
the limit shown in the Table 2 has to be achieved.

24V/150W, enclosed type or open frame
No load power consumption

PSU meet 60335-1


MW proposal:
RSP-150-24 standard unit
61558 (PD3) with design refer to 60335-1

Result:
Customer prefer RS-150 for cost concern.
They get confirmation from certify body that RS-150 with 2 cross
capacitors is sufficient for their approval.
MW modify according to customer requirement but do not
guarantee 60335.
60335 FAQ
60335 Q&A


Questions:
Can I apply 60335 on RSP-150 series?
Answer:
Yes RSP-150 can apply for 60335-1 CB report and
certificate. But without -2, it is not a complete LVD
safety, so the CE will still base on 60950/61558
60335 Q&A


Questions:
Why does Mean Well apply 61558 for RSP-150
Answer:
In the safety standard development, 61558 is more close to
60335. for example, 60335 refer to 61558 for the transformer,
further, 61558 also has a more strict safety distance rules.
A power supply with 61558 can easily meet 60335-1
requirements if the special terms on 60335 are being concerned.
Which means when customer taking a 61558 PSU to the certified
body, they can skip a lot of test and only focus on the difference.
Save time and money.
60335 Q&A


Questions:
What is Mean Well plan for 60335 power supply
Answer:
Refer to Wen/Ted. We will create a series of non-PFC enclosed
type <150W for 60335-1. LRS-150/100/…
New medical open frame type will also take 60335-1 into
concern.
60335 Q&A


Questions:
Can RS-50 (60950) apply for 60335
Answer:
No it is not possible without major redesign of transformer and
PCB. At least it is how Mean Well understood it. However, it is
always suggested to check with customer and their testing
house what is their opinion about meeting 60335-1; sometimes
there is a surprise.
60335 Q&A


Questions:
How about the EMC for Household Electronics ?
Answer:
The corresponding EMC regulation is EN 55014.
It is more or less similar to 55011/55022, but again with
additional tests. PSU that can pass 55011/55022 has very
high chance to pass 55014 also.
60335 Q&A


Questions:
EN 62233 what is that ?
Answer:
Basically, it tells you whether the EM wave of the
product at your hand is harmful to you…
EN 62233 : Measurement methods for
electromagnetic field of household appliances and
similar apparatus with regard to human exposure.
Previously defined in 50366, is a standard to evaluate the
influence of EM field to human. It is a must for GS mark product.
The requirements are different for various applications.
Final evaluation should be done at system level.
60335 Q&A


Questions:
Does USA also apply 60335?
Answer:
There is UL 60335 available but it is not popular.
In general, for US market, the power supply can always apply
UL1012 or UL1310. For the final application, there might be
other specific UL standards for that.
