The MHP650 AC-DC power supply provides upto 650W of output power in three mechanical packages to provide installation flexibility in a range of medical applications. The unit comprises of a main output with voltages from 12V to 48VDC and two peripheral outputs providing a 12VDC fan supply and a 5VDC standby supply which can be utilitsed with the signals and control features of the unit to provide detection of loss of AC input and remote on/off control. Multiple units can used in parallel via the current share facility, providing higher power solutions. Inherently low earth leakage current, and conducted EMC compliance to Class B also simplify higher power system design. Packaged in a compact 8" (203mm) x 4" (102mm) x 2.6" (65mm) and carrying IEC60601 family safety approvals, the MHP650 has a load dependant variable speed fan, is fully protected with overtemperature shutdown and provides full power from -20°C to 50°C and 50% power at 70°C.
