50W PFC MEDICAL ATX POWER SUPPLY FEATURES +5V Stand-by and Remote ON/OFF U, 50W convection cooled with ATX Input Active PFC for medical purpose Power good / Power fail signal Thermal protection EN 6060-, 3rd edition RoHS compliant DESCRIPTION The ATX power supply MPM-85H is a 50W medical device Short Circuit Protection: The PSU will go into hiccup mode against with active PFC for computerised medical applications. This short circuit or over load conditions and will auto-recovery while faulty power supply is EN 6060-, 3rd edition approved and has a conditions are removed very high quality standard and thermal protection. The device Power ON/OFF: The PSU will be turned on when the power ON/OFF utilizes a thermally efficient U channel chassis design and pin is connected to secondary GND convection cooling. Over Voltage Protection: If for some reason the PSU fails to control itself, the build-in over voltage protection circuit will shut down the SPECIFICATION Input Voltage: 90 ~ 264VAC, Continuous input range Input Frequency: AC Input 47-63Hz Hold-up Time: 6ms, Nominal AC input voltage (5VAC, rated load) Inrush Current: Max. 30/60A; Nominal AC input voltage (5VAC/230VAC) one cycle at 25 C Input Current: Max. 4/2A; Nominal AC input voltage (5VAC/230VAC), rated load Efficiency: Nom. 75%, rated load, 5VAC Varies with distribution of loads among output Input Protect: Non-user serviceable internally located AC input line fuse Total Regulation: On condition of a setting output voltage, input voltage from 90-264VAC and output from 0W to 400W Remote Voltage Sense: Compensates for wire drop Warranty: 24 months Storage Temperature: Min. -20 C / Max. +70 C outputs to prevent damaging external circuits. The trigger point is about 5.8-6.4V at +5V. If the OVP occur, PSU cannot be recovered. Over Temperature Protection: When the PSU is operating over the temperature or over load limit, the device will be shut down automatically to protect itself. The protection point is at the temperature of the HS over 0 C. After temperature of HS going down, the power supply will restart automatically. Relative Humidity: Min. 5% / Max. 95% RH, non-condensing Altitude: Operating: Max. 0K Feet, non-operating: Max. 40K Operating Temperature (without the optional top cover ie open frame): Derate linearly above 50 C by 2.5% per deg C to a max. temperature of 70 C. At 00% Load: Max. +50 C - At 50% Load: Max. +70 C Operating Temperature (with the top cover): 30 C at 00% rated load, 40 C at 90% rated load and 50 C at 70% rated load as derating curve. (Please see Note 5 below.) Turn-on Delay: Min. 0.3 sec. / Max. 6 sec.; Time required for initial output voltage stabilization
