Technical content

The MBS400 Series of AC-DC power supplies provides up to 400 W of regulated output power through wide input voltage range 90 – 264 VAC in single outputs of 12, 24, 36 or 48 VDC. The MBS400 Series comes in a 83.0 x 212.0 x 42.0 mm form factor, offering 12 and 5 VSB standby outputs and a full set of protection features. Available control signals include Power Good (Power_OK), remote On/off (PS_ON) and remote sense (+RS). The sealed and full potted package allows an IP67 ingress protection index and can be installed in contact with thermo - conductive part of the system to transfer heat by conduction. The MBS400 Series complies with the latest international safety standards for medical equipment, offering 2x MoPP protection grade and di splays the CE -Mark for the European Low Voltage Directive (LVD).
