Dear Home Sketch Pad Experts,

I recently moved into a new house and I've noticed that my lights tend to dim quite a bit. I asked a friend about this and he said that the area I live in probably suffers from voltage irregularities. He also expressed some concern for the well being of the very expensive 50" plasma HDTV I just bought, and said I needed to protect it. I bought a power strip at Hank's Hardware. Will this do the trick, or do I need something more? Please help.

Sincerely,
Going Mad in Missouri


Dear Going Mad,

Your concerns for your plasma HDTV are well founded. Voltage irregularities can cause sensitive electronic equipment to malfunction and can even lead to severe damage. However, it's going to take a little more than a cheap power strip to keep it safe.

For your situation, I would highly recommend a voltage regulator. As shown on the sketch pad by Super Voltage Regulator Man, a voltage regulator accepts a wide range of voltage inputs from your power supply, and then transforms them to a safe, steady voltage rate that is sent on to connected equipment, keeping it performing correctly and preventing damages from surges. A cheap power strip simply can't provide this level of protection.

As with most power-management products, some technologies are more effective than others. Many voltage regulators use noise-inducing, motorized transformer-based technology. Not only are these products large and expensive, but they are also unreliable and actually add noise to your AC line. This noise ends up masking much of the detail needed for the best-possible resolution on HDTVs. To avoid this, it's best to find a regulator that utilizes electronic circuitry.

I would recommend Furman Sound's 20-amp SPR-20i, which accepts any input voltage from 113 V to 137 V and transforms it to a constant 120 V for connected equipment. The voltage regulator features Series Multi-Stage Protection (SMP), which clamps and dissipates damaging transient voltages without sacrificing itself, and Extreme Voltage Shutdown (EVS) to protect against accidental connections to 208 or 240 VAC, keeping both your HDTV and your regulator alive and well.

It is also the only regulator that filters and purifies AC power with advanced Linear Filtering Technology™ (LiFT), reducing line noise and ensuring optimum performance from connected equipment.

With the SPR-20i, you can plug in your HDTV without fear and reduce line noise for crisper, more detailed images.

Sincerely,
Dexter, Home Sketch Pad Expert
