The QM7 power supply has both medical and ITE safety certifications and offers low acoustical noise. Accepting 90- to 264-Vac, 47- to 440-Hz input, the power supply delivers 1,200 W at low line and 1,500 W with a 150- to 264-Vac input.  With its modular construction, the series can be configured using an online configurator to provide one to 16 independently regulated outputs and includes dc good and remote on/off capabilities. Module output voltages range from 2.8 to 52.8 V and output powers from 300 to 1,200 W. A further subset of option modules provides an ac fail signal, standby voltages (up to 12 V, 2 A) and global remote on/off.
