Vasile, We design & manufacture Telecom supplies (48V up to ~3kW per unit, with parallel operation possible well over the kA range. Noise requirements are <100mV wideband, <2mV pshophometric. (sp?)) But I'm not specifically involved in that area. If you have a specific question I could probably get an opinion however.
