Solid State 12-Pulse 400 HZ Regulated-Transformer-Rectifier-Unit for Pure DC Ground Power
ICS Designed and Built for use on AC ground power units as a source of MIL-STD-704 28 VDC power for DC powered aircraft. 13.5VDC to 29.5 VDC Heavy Duty Regulated Power Supply with 400HZ (50/60Hz based units also available) 3-PH 200V PH-PH input. This is one tough power supply with 800 AMPS continuous output and 2000 AMP Soft-Start Engine Start. Shown on the right is both an exterior view and interior view. In the interior view, the massive 34KVA custom designed transformer can be seen. This is a 200V PH-PH 400HZ three phase input transformer with voltage matched three phase delta and three phase wye outputs. This arrangement allows for a 400 HZ 6 Phase input to the 12-pulse rectifier banks. The resulting 4800 HZ ripple frequency becomes much easier to filter at this frequency and the result is a super low ripple very clean DC output.
