Detail GEFRAN - AC/ DC Power Supplies - SM32
Power supplies – System Lines Power supply DC SM32 DC power supply, DC link current from 185 A up to 2000 A * Power supply from a three-phase mains 400V AC + 10% -15% or 480 V + 10% -15% * DC link current from 185 A up to 2000 A * Protection degree: IP20 ( IP00 for 2000A) * The SM32 converter is suitable to supply power to both single and multiple inverter systems connected to a common DC link. * Marks: CE Features: - Selection of the delay time for the thyristor switching off during a power dip ( 7 times, from 1.1 to 7.7 ms ± 10% ) which can be selected via the dip-switches. - Selection of the undervoltage threshold according to the power supply voltage ( 3 voltages: < _ 370 VDC, < _ 300 VDC and < _ 80 VDC) which can be selected via the dip-switches - Selection of the precharge time for the leveling capacitors ( 5 times, from 2 to 18 seconds ± 15% ) , which can be selected via the dip-switches - Selection of the power supply mains frequency: 50 or 60 Hz - Enabling, via the terminal strip, of the precharge delay.
