Durst cls 301 head

**cdavis324** · 6-Jan-2024, 09:27

Does anyone know the wattage that travels through the timer? I like using a gralab, but don’t want to blow it!

Also, if anyone has a manual, I’d appreciate it.

Are you asking about the timer socket (#36) on the back of the TRA-301?

In that case, I believe the current draw is very little. Probably only what is needed for a relay.

PM you email if you would like the PDF of the manual.

I use the pushbutton Gralab 505. If you're talking about the old Gralab with the luminous Mickey Mouse watch hands, it's underrated for that wattage. I don't know if there's a contactor in the power supply or not, allowing a lower wattage timer. I haven't dissected one of those power supplies in a long time, and rewired my own 301 head for direct 115 voltage anyway.
