Hello,
I just bought a AT8612 programmable load from AliExpress. The guy messaged me saying that it has the wrong input voltage. But I have also noticed the listing has been updated with about a $70 within about a day of purchase.
The manual I found for the unit stated 110v-220v 42hz-62hz.
His listing is for 220v 50hz
Does anyone know if these units support multiple input voltages?

Please read this thread:

There are several posts talking about input voltage and conversion.
To summarize, it seems that they have a (recent) 110V and a (more common) 220V model and they do _not_ have a multi-voltage model (despite the switch in the back).
Given the right wiring in the transformer it is likely possible to rewire it a 220V unit to 110V. Read the thread carefully, starting with Reply #32

At least one user reported receiving a 220V-only transformer that cannot be converted to 110V, with Applent offering to sell the 110V-capable transformer.
I was lucky to receive a 110V unit, so I didn't have to do the conversion (but was prepared to do so).
