New Siglent SPD4000X series power supply

[tautech]

Prices are up on the NA site although this page doesn't seem to show up from their front page yet.    https://siglentna.com/products/dc-power-supply/spd4000x-series/

SPD4323x is $680, SPD4121 is $780 and SPD4306X is $950.

Welcome to the forum.

Pricing is correct and official release is just a few days away.

SPD4121X would have been great but not sure I understand the choice of a 12V maximum output (12V 10A x2, 15V 1.5A x2).
Usually for automotive/battery simulation you'd want around 13 or 14V.
Even for testing a 12V product, you'd sometimes want to try +/-10%.

This is why ~6.3V is somewhat standard (for use with 5V designs).

Ha-ha, I thought it's for vacuum tubes.

I don't know why they chose those specific specs, but each of the 3 models appears to be geared towards different V/A requirements. The SPD4323X would be the only version I would consider, and that has nothing to do with it being the cheapest...which doesn't hurt either.

ETA: Okay, price did matter. I just looked again at the SPD4306X, and those specs would work too, but not for the price.

Hmmm, this is interesting...

SPD4306X:
Weight   26.46 lbs
Dimensions   8.7 × 14.17 × 5.24 in

SPD4121X:
Weight   26.46 lbs
Dimensions   8.7 × 14.17 × 5.24 in

SPD4323X:
Weight   17.64 lbs
Dimensions   8.7 × 11.8 × 5.24 in

Seems like 2 of those might be the same hardware. I wonder what that might inspire. 🥸

For me if designing a lab PSU for use with valves (or 6V batteries) you'd probably choose ~8V.
You can look around at whats commonly available for lab PSUs: 60V, 50V, 30V, 27V, 15V, 6V, etc. Which makes sense for use on 48V, 24V, 12V, and 5V systems. 10-20% headroom.

12V - 10% gives you 10-11V, which no one uses as a standard voltage.

Hmmm, this is interesting...

SPD4306X: Weight   26.46 lbs - 15V 1.5A, 1A, 30V 6A x2
SPD4121X: Weight   26.46 lbs - 15V 1.5A x2, 12V 10A x2
SPD4323X: Weight   17.64 lbs - 6V 3.2A x2, 32V 3.2A x2

I added the voltage specs above. Its a completely different transformer winding I would think.

That's certainly one possibility, but it's not the only possibility. Let's speculate! 😉
