Slightly off topic;

I am looking for a supplier of good transient suppression equipment and a
overvoltage protection unit. My parents are living out in a rural part of
spain and are having problems with the mains killing electronic equipment.
Yes I do know of Farnell, but I was wondering if there was anywhere
cheaper?


Thanks

Ebuyer.co.uk - there are a number of vendors that do 'connected
equipment warranties' - if the equipment on it dies due to a spike, they
replace it the damaged equipment.

I can think of two technologies that actually work. One is a UPS with
batteries where the mains charges the batteries and the batteries power
an invertor.

The other is a CVT - constant voltage transformer.

surge arrestors can only cope with short duration spikes - and most
electronic equipment with SMPS can cope with those anyway.

Example of protectors for short duration transients:

In each case, a short and dedicated earthing connection is essential
for proper operation. A dedicated earthing wire that must be even
separated from other wires so as to not induce transients onto those
other wires.

Overvoltage protectors, such as a UPS, only provide that function if
specifically stated. Most plug-in UPSes do not. Numerical
specifications must state, specifically, an operational voltage well
above 265 VAC. Most UPSes simply connect AC mains directly to the
computer; for example, would not protect from 280 volts. Any 230 volt
appliance will work just fine if voltage rises as high as 265.
Overvoltage protector state, with numbers, operation at even much
higher voltages. Else it does not provide overvoltage protection.

What about a UPS which treats an overvoltage the same as an undervoltage
(i.e. switches to batteries on overvoltage)?

How do you know the problem is 'surges'? I ask because most times I
hear that, it actually isn't. Are you getting failures at lightning
strikes?

See what Watford Control Instruments, have to suggest,
http://www.watfordcontrol.co.uk afair.

Not cheap, but your problem isn't cheap anyway.
