Tripp-Lite SMART1000LCD Tear-Down

Today's Victim: Tripp-Lite SMART1000LCD

When the Canadian price for Tripp-Lite's SMART1000LCD dropped from $200 to $160 CAN ($120 US), I decided to see what corners, if any, the company cut in its consumer-grade units.

As usual for power protection products, the main marketing claims get repeated on every printable surface. In this case, the front and back have English marketing, the two sides have French and Spanish, while the two ends summarize specifications in all three languages.

Even before opening the package, I can already tell I won't like how little Tripp-Lite UPS I got for my money. The SMART1000's cardboard box is about the same size as the unpacked CyberPower LX1500 from last time. The other hint is weight: 7kg for the Tripp-Lite versus 12kg for the CyberPower. Take five seconds to guess what component got sacrificed to save most of that 5kg.

First Impression

Taking the unit out of its packaging confirms what was already obvious: it's tiny. The SMART1000LCD survived shipping through Canada Post without any visible cosmetic damage, although a large piece of packing foam did break off. The enclosure feels quite sturdy overall, which is an easy feat on such a small unit. After all, smaller dimensions leave that much less leverage for flex.

Aside from a Tripp-Lite badge glued near the bottom, the LCD is the only other item up front. The rest of the enclosure is common fare.

How Small Is Small?

For reference’s sake, I decided to stuff the SMART1000 under my desk where the LX1500 resides, and then squeeze in my old BX1000. With all three units aligned at the rear, the SMART1000 is slightly taller than the LX1500, a little narrower and a whopping half as deep. The BX1000 looks like a giant next to both of them.

Second Hint Of Disappointment

I left the SMART plugged in under my desk overnight with nothing connected to it, and when I picked it up to do some measurements later during the day, I noticed that it got quite warm and emitted a distinct 120Hz buzz. I set the UPS up on my bench with a thermometer taped to the side and a layer of foam clamped over the top to see how warm the enclosure got. Since the UPS is supposed to be designed for both horizontal and vertical orientation, it should be perfectly fine with one side covered. I found that its temperature reached 45 °C at 22 °C room temperature, which was much warmer than the LX and my ancient BX.

Can you guess where all of this disappointing heat is coming from?

Green Creds

As I inspected the packaging for an explanation, I noticed this little piece of information intended for the Mexican market. I may not know Spanish, but the black square to the right looks like it says the UPS uses 18W once its battery is fully charged. That’s nearly as much power as leaving a 100W-equivalent fluorescent or LED bulb turned on 24/7. I’ll make sure to measure that after the tear-down.

Upon re-examining the packaging, I realized that the only green certifications on there were RoHS and Green Solutions (recycling), nothing efficiency-related.

Papers, Please!

Tossed haphazardly into the box are:

  • a crumpled registration card
  • a crumpled manual
  • a crumpled promotion leaflet for Tripp-Lite’s keyboard-video-mouse (KVM) switches
  • a crumpled warranty information card for Mexico

It looks like the papers may have been dumped inside the box before the unit.

Accessories

What other goodies do you get with your expensive and hot-running little UPS?

  • an oddly twisted USB cable
  • a two-conductor phone cord

I was half expecting a coax cable too.

An Old Acquaintance

Here is one piece of UPS and surge protection documentation I had not seen in a while: an automated test equipment report. The last time I got one of those was with my SurgeArrest Performance from about 10 years ago.

The ATE checks for wiring errors, battery voltage, the ability to power up from DC power, the output waveform, the alarm squealer, the battery charging function, the status display and the successful completion of a self-test cycle.

That's My Plug

This is an interestingly-shaped plug. Its stepped rectangular design may look a little odd, but it does provide a good grip while keeping fingers as far away from the live pin in the middle as possible. Although it may look like an eyesore on an open wall, I’d say this is functionally one of the better plug designs as far as flat-to-the-wall plugs are concerned. The visual aspect could be improved a little by making it more cylindrical.

Thin Gauge

Just like CyberPower's LX1500, the SMART1000 also uses 3x#16 (1.31mm) conductors in its cord. For a unit rated at only 1000VA and 1440W including surge-only outlets, which should be under 12ARMS under normal operating conditions, this should be perfectly fine… except for one little detail I will cover later.

LCD And Control Module

The display provides basic information in a static configuration: current line voltage, battery charge level as a five-segment bar graph and indicators for voltage regulation buck/boost, battery failure and wiring fault.
