XP Power Extends Family of COTS DC-DC Converters for Military Vehicle and Avionic Applications
XP Power introduced the MTC35 and MTC50 series of commercial off the shelf (COTS) 35 and 50W dc-dc converters aimed at a broad range of military vehicle and avionics applications. These extremely robust and encapsulated board mounted modules accommodate a wide input range from 10 to 40Vdc, and can handle transients up to 50Vdc for up to 100ms. Single output modules are available with + 3.3, + 5, + 12, + 15 or + 28Vdc outputs and can be adjusted between -20% and +10% via an external trim pin.
When used in conjunction with XP Power’s DSF, FSO or MTF series of standard EMI filter modules, the MTC series comply with MIL-STD 1275A/B/C/D and MIL-STD 704A standards for surges and transients, and MIL-STD 461E/F for conducted emissions and susceptibility. The units meet the environmental MIL-STD 810F specification that covers shock, vibration, humidity, temperature, salt spray and altitude.
With its baseplate cooling, the converters are suitable for use across a wide range of operating temperature from - 40 to the maximum case temperature of + 100°C. Unit startup is possible from as low as – 55°C.
Control and signal pins provide the ability to inhibit output, provide thermal warning and converter shutdown, and synchronise converter frequency to an external source in the 400 - 500 KHz range. Remote sense compensates for up to a 0.5Vdc drop on the output.
Prices range from $125.00 for the MTC35 to $139.00 for the MTC50 in 500 unit quantities.
