Belkin PureAV PF31D

I just bought a 50” Plasma HDTV and I wanted something to protect it from power surges. A forty dollar surge suppressor would not suffice.  I wanted something more appropriate for my investment but not too extravagant.  I had two options: an MOV-based power protection or a Series Mode power protection.  The latter being a bit more pricier.   With a budget of roughly a hundred dollars in mind an MOV-based surge suppressor was the only thing that fit the bill.  After numerous research I decided to go with a Belkin PureAV PF31D.  It’s the little sister of Belkin’s flagship PF60.  Here are the main specs:

 

 

 

The PF31D is certainly the beast I was looking for.  When you see images of it on the internet you don’t get the sense of how large this thing really is.  It’s bigger than a VCR and heavy due to its steel shell construction. It can even be rack-mounted with the included brackets.

It’s a great looking unit.  The body is painted gray with a brushed aluminum faceplate.  It stands on four rounded, silver legs which is quite nice. The design is simplistic.  There is a power button at the front that controls the analog and high-current outlets.   An illuminated LCD shows input voltage and output current among other things.  Below that are two buttons for dimming the LCD light and to toggle the Remote function.  The Remote function allows connected devices that support the feature to control the outlets that would otherwise be controlled by the Power button.  An auxiliary outlet at the front provides convenient access if you need to temporarily connect something.

 

 

The outlets on the PF31D are grouped into three isolated filter banks: digital, analog, and high-current filters. On the next page you can see the individual circuitry that make up the filter banks. I suspect you can connect anything to any outlet despite the labels printed on the back.  It’s just that each outlet is optimized for a specific application.  Although, if you have a high-powered amplifier it might be best to connect that to the high-current outlets for best performance.  The other outlets probably limit the output currents if a high-powered amp is connected to them. You'll notice the high-current outlets also have an eight second delay. This is to prevent all your connected devices from drawing current all at once. If you have an amp connected you woudn't want your other devices competing for power when first powered up.
