TDK Lambda GQA120 Series of Industrial grade 120W DC-DC converters have 4:1 input range

TDK Lambda GQA120TDK Corporation announces the introduction of the GQA120 series ofindustrial grade DC-DC converters. Rated at 120W output power, the unitsare available in four robustquarter-brick package styles designed foruse in a wide variety ofapplications and environments.  These includeautomated guided vehicles,portable electronics, ruggedised communicationequipment, track-siderail and marine navigation systems.
 
The GQA120 is available in six standard output voltages, 5, 12, 15, 24, 28 and 48V,adjustableup to ±10% via the trim function to accommodate non-standardvoltages. The units can operate over a wide 9V to 36Vdc input voltage(18-36Vdc forthe 48V model), withstanding a 50Vdc surge for up to onesecond.  Theconverters have efficiencies of up to 91.5% and can operatewithbaseplate temperatures between -40°C and 105°C.
 
All models havethe industry standard quarter-brick pin-out, with achoice of fourpackage types.  A flanged baseplate allows for cold platecooling, or anon-flanged baseplate can be selected for use withstandard quarter-brickheat sinks.  A cost optimised open frameconstruction is available forapplications with airflow.  Alternatively,for harsh environments, anencapsulated plastic case style can bechosen that performs well withminimal airflow in high temperatures.
 
The input to outputisolation is 1,500Vdc for the open frame models,2,250Vdc for thenon-flanged encapsulated construction or 3,000Vdc forthe flangedencapsulated converters.  All models are fully protected,withauto-recovery, against input under voltage, output over voltage,overtemperature and over current. The series is safety certified toIEC/EN/UL60950-1 with CE marking for the Low Voltage and RoHS2Directives.
