I have a bunch of NewPoint surge protectors that I bought on
closeout at MicroCenter for $3-7. These originally sold for $40-70.
Anyway, they have 40V let-through protection, 100->1 EMI/RFI noise
reduction, 1800J and higher maximum energy dissipation (depending
on the model), clamping response time of <1ns, etc. Basically,
the same let-through spec as the APC and BETTER maximum energy
dissipation by a large margin...
These were on the MicroCenter shelf and not marked down, but rang
up at the closeout price. If you have a MicroCenter near you
(forget the Cambridge, MA store...that's the one I cleaned out),
check the shelves for NewPoint protectors. These are the older
models with two outlets on top and six outlets under a flap.
Models AxxxT. The one sitting in front of me (although there
were several) has MicroCenter SKU 128751.
