Heating elements - voltage control

[barls]

how well does it work on the pump

I use one of these for voltage control: http://www.ebay.com.au/itm/VolTage-Resistance-Regulator-Solid-State-Relay-SSR-40A-24-380V-AC-w-Heat-SInk-SY-/252308117274?hash=item3abebc571a:g:sn8AAOSwZQxW2K6u

The increased headroom with 40A helps.

I've got the 10000w model on my 15amp element wired into the 15amp circuit in the spark-o-matic 3000 along with a 15amp ammeter

Seems to work well

Edit: The heat sink is for a SSR on the HERMS circuit

Would be worried if you were kissing that.

I am about to put together a Temp controller because i am lucky enough to acquire a PID controller from work

with a Pt-100 RTD input (temp probe) and a 4-20ma output.I purchased a SSR off ebay-rated at 40amp output a bit of

overkill i know but it will run cooler and handle load easy,Input is 4-20ma, comes from China in a month.This gives me the opportunity

to reduce any offset around set point.SSR was $20.

Danger! Danger! High Voltage...

The solid state voltage regulators shown have 240V on the potentiometer - so make absolutely sure this is grounded correctly. And don't connect one of these to your PID.

SSRs with digital or proportional voltage control have the 240V isolated from the control side, while resistance control has 240V on both sides.
