A 3000va Unit that outputs 3600watts

A customer today reminded me of a great spec on the Tripplite 3000 CRM UPS unit (tl314)

As I have mentioned before, usually a 3000va unit can only provide 2800watts, if its very efficient.  But since this Tripplite unit can be hardwired, the unit can actually output a full 3600watts.   How does that happen?

Well probably because the Tripplite engineers upped the specs on the components, so they can handle 4kva or 40amps of power.  While it is good practice to overspec in manufacturing, very few companies still do it.

Tripplite's commitment to better quality UPSes show on this unit...  And their effort means they have the largest 120volt UPS unit available.

U. P. Asked (You people asked)

You asked:
[Bob] once told me that the one I had [3rd Gen Smart UPS 315 ] was better than the newer ones [4th Gen SUA 3000 - 310b]. Is that still the case?

I responded
The 3rd generation units like yours were built in the US.  APC was small and performance driven product.  Costs of UPSes were minor in the IT world and they could afford to use the best labor and components.  Around the time the 4th generation units were released in 2004, cost consciousness in IT had arrived.  Outsourcing to the 3rd world, pricing pressures and many up starts forced APC to make cost concessions.  Therefore these units were lower quality.  Most people think after Schneider bought them in 07, did they go back to making better equipment.
Bottomline an unused 2003 SmartUPS like the one you have is a better product than today's 2011 SmartUPS.   But, after 10 or so years of use that older 3rd gen unit cant be as good as even a poor quality newer one.

New Racks in Stock

We are updating our Rack section of our website to reflex some new inventory.

We have some nice mid size telco racks and several 42U/48U Dell and APC racks.

Still no 25U units, though.. we are backordered 2 of those... :-(

New Hire...we grow to serve you

Good news... GreenlightUPS is growing enough to bring an additional tech on board.

The Reduced Runtime Model Series...

Normally, Reduced Runtime, would be something that would be undesirable in battery backups systems.  The whole point is to have runtime, so reducing it seems dumb.... but not in some cases...

Our Reduced Runtime series (designated xxR) is when we take the normal battery and replace it with a smaller one.  This smaller battery costs less and the overall unit is less expensive.

Our first product in the Reduced Runtime series is the APC SmartUPS 3000 Tower (310R).  In this case the four 12v 18ah batteries are replaced with four 12v 7ah batteries.   Why?

Many people with copiers need the 3000va capacity of the unit, but dont need the 30mins of runtime.  So the 310R can protect these items for $100 less.

Look for future Reduced Runtime models including

• Tripplite SmartOnline 10kva ... to1096R
• APC SmartUPS 1500va Desktop... 402bR

Random Part of the Month X - AP8641

I just recently started selling PDUs, and it has always amazed me how they can be so expensive.

Case in point, the APC Switched Rack 2G 0U 30amp PDU.

This glorified surge strip sells for $1450.00 from APC.

Sure, its has some neat user controls and a few too many ports... but why do blue LCD screens cost so much?  This unit's earlier version AP7941 can be found at our website for $259.

KnowUPS - Power Conditioning

Frequently, I get requests for the best UPS for power quality and conditioning.

To answer that, I can offer 2 different approaches.

TOPOLOGY
Topology is, loosely, the type of UPS mechanism.  I have written in depth about this.  Online and Line Interactive are the common ones.  Simply, Online type is where output power is always being made by the UPS and Line Interactive type online "makes" the power if something goes wrong.  So, if you want UPS to manufacturer the power output all the time,  Online is the best topology.  But that doesn't necessarily mean its the "best power."


OFFICIAL POWER QUALITY
Technically, power quality is the quality of the voltage; specifically, transient content and voltage magnitudes.   UPSes address both problems and offer redress.  No matter whether its an Online or Line Interactive type UPS,  they output a voltage plus or minus their operational tolerance.
A quick check of some common units, shows some differences in Output Voltage

• APC Line Interactive 5kva (585AB) = +/- 5%
• APC Online 5kva (593g4) = +/- 3%
• Tripplite Online 5kva (to595) = +/- 2%
• Eaton Line Interactive (p5593) = +/- 8%
• Eaton Online 5kva (p9593v) = +/- 2%

So if the goal is 208volt (or other selected voltage output), the best power quality unit is a Online UPS, but with low ranges such as the Eaton or Tripplite.

But, as I have said many times, most IT equipment runs off its own power supply, and the small differences of power quality in the specs isnt worth worry about.

Worry about the quality (or absence) of your Transient Voltage Surge Suppressor....  thats where real power quality should be addressed

My Inner UPS Child... recalls the SmartUPS 2200 208v XL 5U

This unit is famous for being one of the units that I would bring to a deserted island, first hurt my back on, and drove 150 miles out of the way on a vacation to pickup.

The reason is that its a great unit.  It take four large batteries for serious runtime, it has a XL port that can connect to the Super BigMomma battery pack, and has a couple 120volt outputs for non high voltage loads.

While we havent sold that many recently, its still a very good unit and $429 its a best buy

So buy one today, and relive 2003 with a SARS mask, your first Itunes purchase and with no fear of another East coast blackout

Most requested unit we dont have

I would love to be able fulfill every request that we get, but the nature of the refurbished marketplace means I dont have control of availability.  All it takes is for a major University, national chain or large IT reseller to put a bounty on certain items and the prices and availability get skewed.

This month's challenges...

• The Dell Branded SmartUPS 3U - DL3000RM3U (303b)   We have a standing purchase order for 40 that we cant fulfill.  The caused the price to jumped from $419 to $479 to adjust to the demand
• The 120v Online 3U APC - SURTA3000RMXL3U (313g4) is on permanent backorder.  As soon as I get one in it gets snapped up.  I sold the last one for $909, which is $200 more than the price earlier this year. 

RBCs and Battery Page Updated

After several requests, we have re-worked our Replacement Battery store page.  The new pages will help you replace batteries on many server grade units.

We offer the Complete Replacement Battery packs (RBC) and  Replacement Batteries Only (RBO) which require you to re-use the existing trays and leads.

If you need help finding your RB#, contact us or visit this page
