The CHB150W12 series of DC-DC converters offers 150 watts of output power in single output voltages of 5,12, 15, 24, 48VDC. The CHB150W12 series come in industry standard Half-brick format with a wide (12:1) input voltage range of 14 to 160VDC (72VDC nominal) and 3000VAC reinforced isolation.
The CHB150W12 series is compliant with EN50155, EN45545, EN50121-3-2. It has high efficiency up to 91%, allowing case operating temperature range of –40°C to 100°C. An optional heat sink is available to extend the full power range of the unit.
Standard control functions include remote on/off (positive or negative) and +15%, -20% adjustable output voltage. They are fully protected against input UVLO (under voltage lock out), output over-current, output over-voltage and overtemperature as well as continuous short circuit conditions.
The CHB150W12 series is designed primarily for common railway applications with battery voltages of 24V, 36V, 48V, 72V, 96V, 110V
and is also suitable for distributed power architectures, telecommunications, battery operated equipment and industrial applications.
