Re:90 gallon plant tank, suggestions?
David Cooke enquired about a source of transformers for the Dupla heating
cables. For my Dupla cable I used an industrial control transformer that I
purchased from Allied, 1-800-433-5700. The part numbers etc. are as follows:
Stock no. VA rating Price
917-1030 180 38.57
917-1040 225 49.00
917-1050 275 63.21
917-1060 320 66.79
These transfomers are 120/240 volt primary and 24 volt secondary. The VA
rating is roughly the same as watts for this application. These transformers
come with screw type terminals which makes them a little easier to use. Note
that there are two links which need to be changed for 120 vs. 240 volt
operation. I used the 320VA unit and it has been running for roughly one week
with no problems with a 250 watt cable. These transformers are heavy duty and
use alot of steel to improve efficiency.
Allied will ship UPS and they take credit cards.
