The unit includes an isolated enable allowing reference to either the input, output or external source. 

RO-MIL-2211 is a 50W DC-DC converter that operates over a defence temperature range without derating and an efficiency of up to 86%. It has a wide operating input voltage range of 18 to 40V with a 50V surge (80V option available) and the output is isolated from the input. Its compact size is achieved by applying innovative packaging techniques proven in our many avionic programmes.

 

Energy for the output is provided from a high frequency PWM half bridge converter. Overload and overvoltage protection is included. The unit has a remote enable facility.

For more power in the same size package, please see the RO-MIL-2212.

Compact size and high efficiency are achieved by applying innovative techniques proved in our many avionic programmes. Efficiency is optimised across the full range of loads.
