2 Technical ratings: Warning! Hazardous voltages are accessible on the printed circuit boards. In case of damages or technical operations, please disconnect the DC- DC and call MES-DEA. Only authorized personnel can operate on the converter. Parts 1000W converter Working input voltage range From 100VDC to 400 VDC *1 Min. input voltage @ full power 190V *1 Output voltage (with 50 charge) 14.5VDC Output voltage (full power)@ U in >190VDC ~13.3VDC Max. rms input current 6A Max. continuous output current 75A *2 Inrush current 100Â @ U in =400V ; 40Â @ U in =200V U OUT ripple rms @ 75A Output current 650mV rms Internal input fuses 1x16A F / 600V External output fuses 100A FF for semiconductor protection *3 Output impedance (off-mode) >500k Control interface IP degree Enable control, Fault control IP54, except the fan Reverse polarity protection No Over-temperature protection Yes *4 Cooling system By FAN model Papst Multifan 4314 12V or equivalent mounted on the heat sink, automatically controlled Efficiency @ full power >90% Max. encumbrance (l x w x h) [mm] 294x155x130 Notes: *1: the converter can supply full-power with an input voltage above 190VDC; if the input voltage goes under 190VDC, the converter can supply a limited power and the output voltage decreases (due to internal input impedance). If the input voltage goes above 400VDC or under 100Vdc the converter turns itself off, when the input voltage will return in the right window it tries to restart after few seconds. With an external 50Ω output load, the output voltage is fixed to 14.5V; when the input voltage at full power is above 190V, the output voltage decrease at ~13.3V. Doc.
