Advantages
As a low output voltage, highly efficient solution, the GH Series addresses the ongoing need to reduce the overall size and weight of the system together with the increasing requirements of FPGA and other digital circuitries for increased bandwidth and data processing speed of spacecraft electronics
The GH Series was developed using a proven space-level design methodology that includes selection of established reliable components and fully de-rated to the requirements of MIL-STD The devices feature magnetically coupled feedback to insure robust operation under the intended radiation environments.
The output models range from 1.0V to 5.0V with current rating of up to 20A and high efficiency up to 87%. Output is adjustable with an external resistor for a precise output voltage setting with the adjustment range of ±10% of the rated output voltage.
