Unknown Module Board

Can you help me identify this module? The board has name LE180D1S, but Google's can't help.

I'm inclined to believe that this is a ClassD amp. 😕

Looks more like the switching board for a small UPS than an amp.

I agree, look, you have a SG3524 PWM modulator around, maybe some crappy switching amplifier can be done with that, but not for full-range audio.
I also think it is from a switching PSU.

indeed, no output coils, it is from a switching PSU. i agree, a class D amp can be made out of it. it has two IRFZ44 trannies which can be used for this purpose with heatsink, two omron relays, 5 trimpots, voltage regulators, a bunch of smd resistors, beads, smd transistors, connectors, etc.

thanks.
