Compact 120W MIL-spec DC-DC converter in 12V and 15V output versions

The new RO-MIL-2212 is a high-efficiency, high power density single-rail unit comprising an isolated, high-frequency, pulse width modulated push-pull converter. While it is specified to operate from a nominal 28V supply, this versatile power supply will accept a wide input voltage range - from 16-40V (12V output version) and 14.5-40V (15Voutput version). Options include an 80V input surge capability and a variant that will operate from an input as low as 9V. External synchronisation is also available as an option.

The RO-MIL-2212 operates over the military temperature range without de-rating. It is unconditionally stable and does not require additional external components for correct operation. A remote sense facility is provided to compensate for any voltage drop at the load due to the length of the power supply leads. The converter is also equipped with a remote disable function. Both short-circuit and over-voltage protection is provided as standard.

The unit is housed in a machined aluminium enclosure, with a mounting flange configuration that has been designed to optimise thermal impedance and provide adequate vibration support. A PCB-mounting version is also available.

All Roband Electronics DC-DC converters are manufactured at its Charlwood, Horley site in accordance with the company’s approved Quality Management System: BS EN ISO 9001:2000, BS EN 9100 and BS EN 9110.

The RO-MIL-2212’s wide input voltage range and surge capability ensure its suitability for MIL-STD-704 applications.
