The MDP1200-FF front-fan version of Medical Grade power supplies delivers a steady 1000 W over the full input voltage range of 85 – 264 VAC, or a steady 1200 W from 180 VAC and above input line voltage. This dual front-mounted fan version provides the full output rated load up to 60°C regardless of its orientation, which eases integration into power demanding systems. The dual fan rotation speed is digitally controlled to guarantee the minimum required airflow, minimizing audible noise, an unwanted factor in most medical environments. It is available in 24 and 48 VDC output variants.
The MDP1200 series are parallelable for redundant and/or higher power applications, facilitated by the internal OR-ing and current sharing functions. The series offers both analog and digital controls. Analog signals include DC Power-OK, PS-Inhibit, voltage adjustment, remote sense and current share controls. The digital control uses the standard PMBus™ protocol which allows communications and data logging between the power supply and system, and includes monitoring of input voltage, output voltages (+V1), output current (on +V1), current sharing, thermal health, fan health, life hours, power supply and status information. Additional alarm signals include fan fault, protections failure (OV, OC, OT) and voltages out of specifications. An LED provides visual indication of power supply status.
The MDP1200 series is approved to the 3rd edition of the ANSI/AAMI ES60601-1, IEC/EN 60601-1 standards for medical grade power supplies, including 2x MoPP means of patient protection and BF appliances compatibility, and complies with the EN 55011, EN 60601-1-2 Class B limits for conducted and radiated emissions, IEC/EN 61000-3 for harmonic and flicker, and IEC/EN 60601-1-2 4th edition for EMC immunity standards.
