Class-D modules no-signal power
Just for my reference and curiosity. What is the idle power consumption of several Class-D modules? I mean during power-on with no signal (not in shutdown mode)
Hypex UCD400 says around 8W at +/-65V, for UCD700 that's around 15W with +/-90V rails, but have no data about ZAPPulse, etc. Anyone can help?
Our coldamp BP4078 modules, when connected with the main supply only (no external gate or modulator voltage), lose around 10W at +/-60V rails, less with lower voltage, obviously. At that voltage they can output around 700W at 2 ohm.
You can reduce around 3W with external +/-12V for the modulator, and another 3W if you feed the gate driver externally too.
Shutdown power consumption is around 5W.
Hope this helps.
