Relec Electronics adds versatile DC/DC converters from Cincon

DC/DC converters, the CQB75W8 and CHB150W8 series from Cincon, have an 8:1 input range and are suitable for a variety of demanding applications in industrial and military environments.

The CQB75W8 75W quarter-brick and CHB150W8 150W half-brick DC-DC converters both have an input range 9V to 75V DC, making them suitable for all common battery and bus voltages and 12V, 24V, 36V and 48V systems.

Both series are suited for distributed power architectures, telecommunications, battery operated equipment and industrial applications, as well as demanding railway environments applications operating from 24V, 36V, 48V supply voltages.

The CQB75W8 75W DC/DC converter is designed for use in energy critical systems. It has very low no load power consumption (10mA) and an input range of 9V to 75V DC and outputs of 12V to 48V DC and 3,000V AC input to output isolation.

The second series is the CHB150W8 150W DC/DC converter. It is a half brick format with an input range of 9V to 75V DC and  outputs available of 12V to 48V DC and 1,500V DC input to output isolation.

Both the CQB75W8 and CHB150W8 series can withstand an input surge of 100V for 100mS. The addition of EMC filter components, enables the DC/DC converters to be used in military systems which are required to meet RTCA DO-160E, DEF STAN 6-15 part 6, Mil-STD-1275D and Mil-STD-704A.

Both series of DC/DC converters are qualified to a stringent regulations, including EN45545-2 fire and smoke, EN 50155 (EN 61373) shock and vibration for railway use, UL62368-1 2nd edition reinforced insulation, CB test certificate IEC62368-1 and EN50155/EN50121-3-2 with external circuits. They are also qualified for operation up to a height of 5,000m.

Other features are efficiency up to 90 per cent, allowing for a wide case operating temperature range of -40 to +105 degrees C. Standard control functions include remote on/off (positive or negative) and +15, -20 per cent adjustable output voltage (single output only).

All units are fully protected against input under voltage lock-out, output over-current, output over-voltage and over-temperature and continuous short circuit conditions.

Optional heat-sinks are available to extend the operating temperature range of the modules.

Both the CQB75W8 and CHB150W8 are available to sample now from Relec Electronics, with production lead times of six to eight weeks.

The technical team at Relec is available now to guide customers through the design in process, provide samples and commercial support throughout the design process and into production.
