UL Standards Update: UL1950 vs. UL60950
You may start seeing a new UL standard on ITE type power supply
labels. UL's new standard for ITE power supplies, UL60950-1 became
effective in April, 2003. It replaced the older UL60950, which was
published back in December 2000. The UL60950 and the new UL60950-1
where developed for the purpose of more closely meeting the requirements
to IEC60950, which is a global standard used by many countries.
The old UL1950 was replaced by the first UL60950 standard for all
newly developed products, but due to numerous changes to UL60950
(third edition), it has been upgraded to UL60950-1. This new UL60950-1
(First Edition) is based on the global IEC 60950-1 (First Edition).
If you are selling your products abroad, these new changes will
allow your products be more easily certified/recognized by European
safety agencies, and reducing the time to sell your products into
the international markets.
RSI Power Restructures Internal Operations
to Better Serve Its Customers
After a brief period that saw RSI Power's sales and distribution
operations physically separate from one another, they are once again
under a single roof. The decision to separate the two was made in
an effort to improve the efficiency of warehousing and distribution
processes. While efficiencies in these areas did increase, the impact
it had on customer service was not as positive. The decision to
create a new, centralized location was made shortly thereafter,
and by the end of May (and after a good deal of remodeling and rebuilding),
a new command central for RSI Power was put into service.
New square footage was absorbed from neighboring businesses to make
room for increased warehousing capabilities, new offices, a shipping
and receiving department and a brand new laboratory for RSI's lead
engineer, Rick Araujo. The additional space was procured in the
anticipation of steady growth for RSI Power, Inc, NuPower, the industry,
and the economy. There has been much speculation that breakthroughs
in LED technology will fuel enormous growth for companies like RSI
in the next few years -- as products improve and prices steadily
drop -- and RSI has prepared itself to keep pace with this growth
while retaining unparalleled levels of customer satisfaction.
We invite all of our customers to come and tour our new facilities
when in the Las Vegas area. We're looking forward to growing together
with our customers, today and in the future, and are happy to demonstrate
our continued commitment to their success.
Power FAQs
Every month in this section we will address a question we are often
asked by our customers. If you have one you’d like answered, please
email your question to jim@rsipower.com.
Q: "My system uses six power supplies,
each rated 20A inrush current. Do I really need 120 amps of circuit
breaker protection?"
A: No, you don't. Multiple power supplies
are common in many installations. While inrush current (when the
power supply is first energized) can indeed be 20 amps, actual operating
current draw at full load is usually 2-3 amps. So, either manually,
or with a simple delay circuit, apply the AC to one power supply
at a time. Since we're talking milliseconds, the delay needn't be
much. Now you're back to a single 20 amp breaker.
Q: "I need both plus and minus voltage
in my system. I see my power supply has both plus and minus taps.
Can I use both?"
A: No, you can't. On a single output
power supply, the terminals are plus OR minus, not both. That's
why it's called a single output. If you need both plus AND minus,
you must use a dual output power supply. The dual will contain the
proper components and circuitry to deliver both plus and minus voltages.
