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

Roband Electronics has launched a compact military specification DC-DC converter in 12 and 15V output versions providing a power output of 120W from a package measuring 76.3 x 38.2 x 10.2mm.

The RO-MIL-2212 is a 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, the power supply will accept an input voltage range from 16 to 40V (12V output version) and 14.5 to 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. According to Roband, the RO-MIL-2212 operates over the military temperature range of without de-rating. It does not require additional external components for correct operation and 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.
