Roband Electronics has added the RO-MIL-2213 power supply to its compact military-specification DC-DC converter range.

The RO-MIL-2213, which is supplied in 3.3V and 5V output versions, is capable of delivering a 20A output current from a 76.3 x 38.2 x 10.2mm package.

The high-efficiency, high-power-density single-rail unit comprises 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 an input-voltage range from 12-40V (5V output version) and 14.5-40V (3.3V output 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-2213 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.

Roband’s converters are manufactured 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-2213’s wide input voltage range and surge capability ensure its suitability for MIL-STD-704 applications.
