The UD80 can be powered from 10V to 35V and the power supply requirements and the output power will vary depending on the speaker impedance. The absolute max is 36V, however a 36V might output slightly above 36V which can damage the UD80.
Power supply options
We have several options for power supplies for the UD80. As a general option we recommend the 35V 6A supply (soon available). If you know you’ll use only 4 ohm speakers, then you can chose the 24V 8A supply instead (soon available). We have also used the 32V adjustable power supply with good result. This 32V5A supply has very low ripple, and will be able to make the amp output 2 x 50W at 8 ohm and 2 x 25W @ 4ohm.
The Connexelectronic SMPS300R can be used if you don’t mind a little bit of DIY. Use 38V turned down to 35 for 8 ohm speakers, and 28V power supply can be adjusted down to minimum for 4ohm speakers. The 200W SMPS power supply we’re selling will also work good and requries only minimal tweaking.

Questions: (moved from reviews)
Hi, the power is DPS based and resolution is 8 bit. We will add a inside photo soon.
