Can multiple electric heaters be powered through a single SCR Controller. I have an application where ideally 3 to 6 heaters would be controlled by a single SCR controller. Each heater is 750 watts and voltage is 208/1/60V ?
Hi Maxwell,
You can connect multiple heaters to a single SCR controller. The heaters are wired in parallel then wired in a series circuit with the SCR and your power source. The maximum number of heaters would depend on the maximum current rating of the SCR.
In your example (6) heaters x 750 watts each = 4500 total watts
Current = 4500 / 208 = 21.63 amps The SCR needed would have a max current rating of 22 amps or greater for this application
Best regards,

Looking for a power source to connect to the coils of a 3-phase motor. I do not want to run the motor, rather, to run current through the windings and heat them up, drying out wet windings. Coils are inductive loads; will it work to heat them up?
