DVGF+2800T Series
Product Description
The DVGF series of high-reliability DC-DC converters provide decades of successful critical mission support. Operable over the full military (-55 °C to +125 °C) temperature range with no power derating, the DVGF series unique input, and output filters dramatically reduce input and output noise performance. While operating at a nominal fixed frequency of 450 kHz, these regulated, isolated units
utilize a high-speed magnetic feedback design and well-controlled under-voltage lockout circuitry to
eliminate slow start-up problems.
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MIL-PRF-38534 and MIL-STD-883.
