Dear Support Team ,
I am looking for STACO Variac Variable Transformer With complete accessories and manuals.
Our requirements are
Input: 1phase, 240V, 60Hz
Output: 0-560V, 60Hz, 9.5A @ 300V, 4.1A @ 560V.
Please advise the correct part number in the STACO Variable transformer range.
Regards
Hello @mohammed.afzalkhan,
The core STACO part number is 1520.
DigiKey offers a two-ganged unit STACO 1520-2.
Unfortunately, I was not able to locate a single unit. Ref: VARIAC 240VAC Input, 0-560VAC Output.
Perhaps you could contact ISE directly for a single unit.
Sincerely,
Aaron

Hi @APDahlen ,
Thank you for the response.
Appreciate your suggestion of a two-ganged unit STACO 1520-2 offered by DigiKey.
After referring to the product catalogue, I have understood that the 2-ganged unit STACO 1520-2 has an Input voltage 240VAC and output 0-560VAC, which looks suitable for our application.

However, I am not sure about the difference between a 2-ganged unit and a single unit..…does that impact the performance of the VARIAC?
Also, the picture shown in your message is uncased and open. Does DigiKey offer a cased/covered version?
Regards
Hi @mohammed.afzalkhan,
The term “gang” identifies the number of units bolted together. This page presents a few options:
With regards to your application, please consider this document to explore the connections between variable transformers. My understanding is that you are looking for connection 3.
Recommend you contact ISE directly to explore a custom configuration as I do not see a solution in DigiKey’s offerings. They can be reached as sales@iseinc.com
Best wishes,
