Datasheets (PDF)
Datasheet - MDP520

The series is currently available in 24, 36, 48 and 56 VDC output variants. It has a +5V 1A stand-by output, and Power Good, Remote On/Off and Sense Terminal controls. The series can operate over the full -40 to 80ºC ambient temperature range with de-rating applied above 50ºC and below -20ºC start up.

The series complies with the 3rd edition of the IEC60601-1 safety standard for medical equipment, offers 2xMoPP means of patient protection, and is suitable for BF rated applied parts under certain conditions, UL8750 for LED lighting, and its design and construction make it compatible with IEC60335-1 / 61558-1 standards for household appliances. The series meets the EN55032-1/15 EMC limits of Class B for conducted and Class A for radiated emissions, and the IEC/EN61000-3, IEC/EN61000-4 for harmonic content and EN55024, EN61000-6-2, IEC/EN60601-1-2-4 for immunity.
