What output current do you need ? Does it need aux. voltage as well ?

Cristi, which SMPS do you recommend for your TA2022 board?
Thanks

SMPS250 should be big enough – it’s for 2 TC2000/STA508 modules into 8 ohm drivers. I don’t need another AUX voltage, as I can get one off the SMPS500R for my BIPS modules.

Also, is the SMPS500R ok for a TA3020v3b with IRFP4228: +-60V into stereo 8ohm? I’m a bit concerned about the voltage drop you mentioned in another thread: “the A500SMPS use half-bridge resonant topology, the output voltage is not regulated and drop about 10% at maximum power. this is the classic topology used in >80% of the PA amplifiers.” It won’t be run with sine waves or anything, just music.

Thanks

As fb pointed put, the SMPS250 works fine for TA2022 amplfier. in fact, the amplifier has connections for +V and -V, so the smps can be connected directly there, skipping the rectifier bridge.
the A500SMPS has no-regulated outputs, but the SMPS500R, has regulated output voltage, which does not drop when the current draw increase. it uses LLC resonant topology, with efficiency over 90%.

Just to make sure I got it: the rectifier bridge has to be removed and in its place the SMPS is connected, right?

On the actual version and previous one, since about one year ago, there are connections on the pcb in front of the rectifier bridge for +V and -V. the smps output should be connected to this pins directly and the gnd can be connected to the terminal block, and the bridge no need to be removed.

Mhhh....a pic says more than a thousand words..... I don't know how to insert it here, but perhaps you can provide me with an email address off the forum - thx.

visually : look at page 4 of the TA2022 webpage pdf manual.
Top right of the pcb you see -Vcc and +Vcc holes.

You can also look at post #11 of this thread. It has a schematic on how to plug smps with TA2022.

Okay.....I think I found them......I was only confused as there seem to be some smt parts below the board as well and the holes are soldered and not open....but the smt parts are probably just next to the holes.
