70170AC 1. (115Vac, Hz Input) 170W, 28V Single Output, Airborne PFC Power Supply

Transcription

1 7070AC (5Vac, Hz Input) 70W, 8V Single Output, Targe ng Point of Load (POL) applica ons, the 7070AC provides a single 8Vdc output at up to 6A con nuous output current. It meets the most stringent airborne requirements including those for variable frequency 5Vac generator systems over the wide frequency range of Hz and RTCA/DO 60D category M emissions. Efficiency exceeds 80% at ½ to full output load helping to keep internal heat dissipa on to a minimum. The 7070AC is capable of providing uninterrupted ridethrough at full output load during momentary input AC brown out condi ons for up to 00mSec. Standard protec on features are built in in to assure years of fault tolerant and reliable opera on in the harshest environments. Weighing less than 36 ounces, the 7070AC is housed in an aluminum enclosure with outer dimensions of 8.0 x 4.75 x.4. The top cover is perforated; the lower U Chassis accepts five #4 screws to facilitate system moun ng. Interconnec on is accomplished using a single Samtec right angle connector. A second supply configura on is available, the 7070AC, that meets all of these same requirements except the output is scaled down to provide a maximum output current of 3.6A (00W output power). This configura on provides greater than 330mSec uninterrupted ride through and complies with all of the same standards, including the wide frequency distor on requirements, over the output power range of 50W to 00W. Please contact PPI s sales department for further informa on on this supply configura on.
