Cost-effective DC/DC converters have wide input ranges
30 November 2022 
The REC300H-W is rated at 300W output and has a wide 9.0 to 36V DC input. Output options are 12, 15, 24 and 48V DC isolated to 3kV DC/minute.
The second model is the REC150H-UW with 150W output and a wide input range of 9.0 to 75V DC. It has the same output voltage options and additionally 28 and 54V DC, to suit avionic systems and PoE applications, isolated at 2.5kV DC/minute.
Both DC/DC converters are tightly regulated and protected against input under-voltage, short circuits, and output overload and over-voltage. Outputs are all adjustable by +/-10%, with remote sensing. An enable input is also provided.
The parts are fully sealed and operate across the load range up to a maximum baseplate temperature of 105°C, making them suitable for demanding environments. Class A and B EMC specifications can be met with external filtering.
The half brick has a footprint of 57.9 x 61mm and a height of 12.7mm with baseplate cooling. Through-hole pin connections for both DC/DC converters are in a standard
