SMHF 100 krad(Si) Converter

The SMHF Series DC-DC converters now operate up to 45V input and offer up to 15 watts of output power with single outputs of 2.5, 3.3 and single or dual outputs of 5, 12 or 15 VDC. The SMHF converters now offer reduced output ripple noise, improved start-up response and recovery and improved step load response and recovery. They operate over the full military temperature range of -55 to +125 °C, the small footprint of 1.48 x 1.13 x 0.33 inches saves board space for critical missions. The SMHF converters offer screening options to Space Prototype (O), Class H or Class K and Radiation Hardness Assurance (RHA) levels of “-” (O, no rating), “P” 50 krad(Si) or “R”, 100 krad(Si) per MIL-PRF-38534.

81-084 Transformer Rectifier Unit

300 Amp TRU

The model 81-084 Transformer Rectifier Unit provides the ultimate in reliability for aircraft dc bus power. Rated at 300 amps with 28 V dc output, this unit is designed for commercial aircraft applications and operates from 115 V ac, 3-phase, 400 Hz input power. This model is a passively regulated unit that offers very low current THD (<12%) and has standard features that include fan cooling, over-temperature sensing and fan underspeed detection.
